UNITED CONTINENTAL HOLDINGS, INC. AND UNITED AIRLINES, INC.

COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

United Continental Holdings, Inc. (together with its consolidated subsidiaries, “UAL” or the “Company”) is a holding company and its principal, wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, “United”). This Quarterly Report on Form 10-Q is a combined report of UAL and United including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United’s operating revenues and operating expenses comprise nearly 100% of UAL’s revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL’s assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words “we,” “our,” “us,” and the “Company” in this report for disclosures that relate to all of UAL and United.

The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the “SEC”). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company’s financial position and results of operations. The UAL and United financial statements should be read together with the information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Annual Report”) and Current Report on Form 8-K filed on April 25, 2013. The Company’s quarterly financial data is subject to seasonal fluctuations and historically its second and third quarter financial results, which reflect higher travel demand, are better than its first and fourth quarter financial results.

NOTE 1—FREQUENT FLYER ACCOUNTING

Frequent Flyer Awards. The Company revised the estimated selling price of miles as a prospective change in estimate, effective January 1, 2012, based on the price at which the Company sells miles to Star Alliance partners in its reciprocal frequent flyer agreements as the best estimate of the selling price for these miles. Any changes to the composition of Star Alliance airline partners could result in a change to the amount and method we use to determine the estimated selling price. On February 14, 2013, US Airways Group, Inc. announced an agreement to merge with AMR Corporation and its intent to exit Star Alliance as a result of such merger. We are currently evaluating the potential impact of any changes to the estimated selling price of miles as a result of this merger.

NOTE 2—NEW ACCOUNTING PRONOUNCEMENTS

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02 (“ASU 2013-02”), Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Some of the key amendments require the Company to present, either on the face of the statement of operations or in the notes, the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, the Company is required to cross-reference to other disclosures that provide additional detail about those amounts. ASU 2013-02 became effective for the Company’s annual and interim periods beginning January 1, 2013, and the required disclosures are included in Note 11 of this report.

NOTE 3—EARNINGS (LOSS) PER SHARE

The table below represents the computation of UAL’s basic and diluted earnings (loss) per share amounts and the number of securities that have been excluded from the computation of diluted earnings (loss) per share amounts because they were antidilutive (in millions, except per share amounts):

During the second quarter of 2013, UAL issued approximately 22 million shares of UAL common stock pursuant to agreements that UAL entered into with certain of its securityholders in exchange for approximately $189 million in aggregate principal amount of UAL’s outstanding 6% convertible senior notes due 2029 held by such securityholders. The newly issued shares of UAL common stock are included in the determination of basic weighted average shares outstanding for the three and six months ended June 30, 2013. The Company retired the 6% convertible senior notes acquired in the exchange.

NOTE 4—INCOME TAXES

Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because we have concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

United files a consolidated federal income tax return with UAL. Under an intercompany tax allocation policy, United computes, records and pays UAL for its own tax liability as if United were a separate company filing a separate return. In determining its own tax liabilities, United takes into account all tax credits or benefits generated and utilized as a separate company and it is compensated for the aforementioned tax benefits only if it would be able to use those benefits on a separate company basis.

NOTE 5—EMPLOYEE BENEFIT PLANS

Defined Benefit Pension and Other Postretirement Benefit Plans. The Company’s net periodic benefit cost includes the following components (in millions):

Total	$	113		$	83		$	88		$	85

During the three and six months ended June 30, 2013, the Company contributed $38 million and $79 million, respectively, to its tax-qualified defined benefit pension plans.

Curtailments, Settlements and Plan Remeasurements. During June 2013, the Company announced it would freeze benefits for management and administrative employees under one of its defined benefit pension plans, effective December 31, 2013. As a result, the Company recognized a $2 million curtailment loss in earnings in the second quarter. The Company also recognized a settlement gain of $1 million in earnings resulting from certain lump-sum payments under a separate defined benefit pension plan. Application of curtailment and settlement accounting required the Company to remeasure the assets and liabilities of the two plans in the second quarter. The Company remeasured the pension plans’ liabilities using an average weighted discount rate of 4.74% compared to the year-end 2012 discount rate of 4.24%. As a result of the remeasurements, curtailment and settlement, the projected benefit obligation of the plans decreased by $434 million and Other comprehensive loss decreased by an actuarial gain of $442 million, of which approximately $84 million resulted from the curtailment. These items will also result in a decrease of approximately $30 million in the expected net periodic benefit cost for the remainder of 2013. The Company recognizes the earnings impacts of its pension plans in Salaries and related costs in the statements of consolidated operations.

Share-Based Compensation. In February 2013, UAL granted share-based compensation awards pursuant to the United Continental Holdings, Inc. 2008 Incentive Compensation Plan. These share-based compensation awards include approximately 0.5 million shares of restricted stock and 0.5 million restricted stock units (“RSUs”) that vest pro-rata over three years on the anniversary of the grant date. The time-vested RSUs are cash-settled based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. In addition, the Company granted 1.3 million performance-based RSUs that will vest based on the Company’s return on invested capital for the three years ending December 31, 2015. If this performance condition is achieved, cash payments will be made after the end of the performance period based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. The Company accounts for the RSUs as liability awards. The table below presents information related to share-based compensation (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012

	June 30, 2013	December 31, 2012
Unrecognized share-based compensation	$45	$33

(a) Includes $3 million and $11 million of expense recognized in merger integration-related costs for the three and six months ended June 30, 2013, respectively. Includes $3 million and $7 million of expense recognized in merger integration-related costs for the three and six months ended June 30, 2012, respectively.

Profit Sharing Plans. In 2013 and 2012, a majority of all employees participate in profit sharing plans, which pay 15% of total pre-tax earnings, excluding special items and share-based compensation expense, to eligible employees when pre-tax profit, excluding special items, profit sharing expense and share-based compensation program expense, exceeds $10 million. Eligible U.S. co-workers in each participating work group receive a profit sharing payout using a formula based on the ratio of each qualified co-worker’s annual eligible earnings to the eligible earnings of all qualified co-workers in all domestic workgroups. The international profit sharing plan pays eligible non-U.S. co-workers the same percentage of eligible pay that is calculated under the U.S. profit sharing plan. Profit sharing expense is recorded as a component of salaries and related costs in the consolidated statements of operations. Our profit sharing plan will change in 2014. Beginning with 2014, pilots’ share of profit sharing payments will be limited to an amount that is their pro-rata share of 10% of the Company’s profit up to a pre-tax margin of 6.9% and 20% of the Company’s profit in excess of a pre-tax margin of 6.9%. The profit sharing plan for the other workgroups is unchanged.

As of June 30, 2013, the Company’s auction rate securities, which had a par value of $125 million, were variable-rate debt instruments with interest rates that reset every 7, 28 or 35 days, depending on the terms of the particular instrument. These securities are backed by pools of student loans guaranteed by state-designated guaranty agencies and reinsured by the U.S. government. All of the auction rate securities that the Company holds are senior obligations under the applicable indentures authorizing the issuance of the securities.

As of June 30, 2013, United’s EETC securities, which were repurchased in open market transactions in 2007, have unrealized gains of $3 million. All changes in the fair value of these investments have been classified within accumulated other comprehensive income.

United’s debt-related derivatives presented in the tables above relate to (a) supplemental indenture agreements that provide that United’s convertible debt is convertible into shares of UAL common stock upon the terms and conditions specified in the indentures, and (b) the embedded conversion options in United’s convertible debt that are required to be separated and accounted for as though they are free-standing derivatives as a result of the United debt becoming convertible into the common stock of a different reporting entity. The derivatives described above relate to the 6% convertible junior subordinated debentures due 2030 and the 4.5% convertible notes due 2015. These derivatives are reported in United’s separate financial statements and eliminated in consolidation for UAL.

(a) Broker quotes obtained by a third-party valuation service.

(b) Represents the credit risk premium of the EETC structure above the risk-free rate that the Company has determined market participants would use in pricing the instruments.

(c) Represents the range in volatility estimates that the Company has determined market participants would use when pricing the instruments.

(d) Represents the range of Company-specific risk adjustments that the Company has determined market participants would use as a model input.

Valuation Processes—Level 3 Measurements—Depending on the instrument, the Company utilizes broker quotes obtained from third-party valuation services, discounted cash flow methods, or option pricing methods, as indicated above. Valuations using discounted cash flow methods are generally conducted by the Company. Valuations using option pricing models are generally provided to the Company by third-party valuation experts. Each reporting period, the Company reviews the unobservable inputs used by third-party valuation experts for reasonableness utilizing relevant information available to the Company from other sources.

As of June 30, 2013, the Company began using broker quotes obtained from a valuation service (in replacement of a discounted cash flows method) for valuing auction rate securities. This approach provides the best available information.

Sensitivity Analysis—Level 3 Measurements—Changes in the structure credit risk would be unlikely to cause material changes in the fair value of the EETCs.

The significant unobservable inputs used in the fair value measurement of the United convertible debt derivative assets and liabilities are the expected volatility in UAL common stock and the Company’s own credit risk. Significant increases (decreases) in expected stock volatility would result in a higher (lower) fair value measurement. Significant increases (decreases) in the Company’s own credit risk would result in a lower (higher) fair value measurement. A change in one of the inputs would not necessarily result in a directionally similar change in the other.

Fair value of the financial instruments included in the tables above was determined as follows:

20

Description	Fair Value Methodology
Cash and cash equivalents	The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term investments and Restricted cash	Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, (c) internally-developed models of the expected future cash flows related to the securities, or (d) broker quotes obtained by third-party valuation services.
Fuel derivatives	Derivative contracts are privately negotiated contracts and are not exchange traded. Fair value measurements are estimated with option pricing models that employ observable inputs. Inputs to the valuation models include contractual terms, market prices, yield curves, fuel price curves and measures of volatility, among others.
Foreign currency derivatives	Fair value is determined with a formula utilizing observable inputs. Significant inputs to the valuation models include contractual terms, risk-free interest rates and forward exchange rates.
Debt	Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities.
Convertible debt derivative asset and option liability	United used a binomial lattice model to value the conversion options and the supplemental derivative assets. Significant binomial model inputs that are not objectively determinable include volatility and discount rate.

NOTE 7—HEDGING ACTIVITIES

Aircraft Fuel Hedges. To protect against increases in the prices of aircraft fuel, the Company routinely hedges a portion of its future fuel requirements. As of June 30, 2013, the Company had hedged approximately 47% and 18% of its projected fuel requirements (942 million and 706 million gallons, respectively) for the remainder of 2013 and 2014, respectively, with commonly used financial hedge instruments based on aircraft fuel or closely related commodities, such as heating oil, diesel fuel and crude oil. As of June 30, 2013, the Company had fuel hedges expiring through December 2014. The Company does not enter into derivative instruments for non-risk management purposes.

Upon proper qualification, the Company accounts for certain fuel derivative instruments as cash flow hedges. All derivatives designated as hedges that meet certain requirements are granted hedge accounting treatment. The types of instruments the Company utilizes that qualify for special hedge accounting treatment typically include swaps, call options, collars (which consist of a purchased call option and a sold put option) and four-way collars (a collar with a higher strike sold call option and a lower strike purchased put option). Generally, utilizing hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the underlying fuel is consumed and recorded in fuel expense. The Company is exposed to the risk that its hedges may not be effective in offsetting changes in the cost of fuel and that its hedges may not continue to qualify for hedge accounting. Hedge ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume fuel. To the extent that the periodic changes in the fair value of the derivatives are not effective, that ineffectiveness is classified as Nonoperating income (expense): Miscellaneous, net in the statements of consolidated operations.

The Company also utilizes certain derivative instruments that are economic hedges but do not qualify for hedge accounting under U.S. GAAP. As with derivatives that qualify for hedge accounting, the purpose of these economic hedges is to mitigate the adverse financial impact of potential increases in the price of fuel. Currently, the only such economic hedges in the Company’s hedging portfolio are three-way collars (which consist of a collar with a cap on maximum price protection available). The Company records changes in the fair value of three-way collars to Nonoperating income (expense): Miscellaneous, net in the statements of consolidated operations.

If the Company terminates a derivative prior to its contractual settlement date, then the cumulative gain or loss recognized in AOCI at the termination date remains in AOCI until the forecasted transaction occurs. In a situation where it becomes probable that a hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. All cash flows associated with purchasing and settling derivatives are classified as operating cash flows in the condensed statements of consolidated cash flows.

21

The Company records each derivative instrument as a derivative asset or liability (on a gross basis) in its consolidated balance sheets, and, accordingly, records any related collateral on a gross basis.

The following tables present information about the financial statement classification of the Company’s derivatives (in millions):

Derivative Credit Risk and Fair Value

The Company is exposed to credit losses in the event of nonperformance by counterparties to its derivative instruments. While the Company records derivative instruments on a gross basis, the Company monitors its net derivative position with each counterparty to monitor credit risk. Based on the fair value of our fuel derivative instruments, our counterparties may require us to post collateral when the price of the underlying commodity decreases, and we may require our counterparties to provide us with collateral when the price of the underlying commodity increases. The following table presents information related to the Company’s derivative credit risk as of June 30, 2013 (in millions):

Commitments. On April 29, 2013, United entered into an agreement to purchase 30 Embraer EMB175 regional jets, scheduled for delivery in 2014 and 2015.

On June 17, 2013, United entered into supplemental agreements to United’s 787 aircraft purchase agreements with The Boeing Company (“Boeing”) to add to its existing firm order of Boeing 787 widebody aircraft ten Boeing 787-10 aircraft, convert an existing firm order for ten Boeing 787 aircraft into Boeing 787-10 aircraft and make certain other changes to those agreements. On June 19, 2013, United entered into amendments to its A350 purchase agreement with Airbus S.A.S. (“Airbus”) to add to its existing firm order of Airbus A350 widebody aircraft ten Airbus A350-1000 aircraft, convert its existing firm order for 25 Airbus A350-900 aircraft into Airbus A350-1000 aircraft and make certain other changes to the agreement. The Company expects to take delivery of the Boeing 787-10 aircraft and Airbus A350-1000 aircraft between 2018 and 2024.

23

As of June 30, 2013, UAL and United had the following commitments to purchase aircraft:

UAL Aircraft Commitments. UAL had firm commitments to purchase 100 new Boeing 737 MAX 9 aircraft scheduled for delivery from 2018 through 2025. UAL also had options to purchase additional Boeing 737 MAX 9 aircraft. UAL intends in the future to assign its interest under the purchase agreement for the 737 MAX 9 aircraft to United.

United Aircraft Commitments. United had firm commitments to purchase 199 new aircraft (59 Boeing 787 aircraft, 75 Boeing 737 aircraft, 35 Airbus A350-1000 aircraft, and 30 Embraer EMB175 aircraft) scheduled for delivery from July 1, 2013 through 2025. United also had options and purchase rights for additional aircraft. In the second quarter of 2013, United took delivery of six Boeing 737-900ER. In the remainder of 2013, United expects to take delivery of twelve Boeing 737-900ER aircraft and two Boeing 787-8 aircraft.

United had arranged for EETC financing of 14 Boeing 737-900ER aircraft, six of which were delivered during the second quarter of 2013 and two of which are scheduled to be delivered during the remainder of 2013. United also has arranged for EETC financing of one Boeing 787-8 aircraft and a bank debt financing commitment for one Boeing 737-900ER aircraft scheduled for delivery in the second half of 2013. In addition, United had secured backstop financing commitments from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. However, the Company does not have backstop financing or any financing currently in place for its other firm aircraft orders. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all. See Note 9 of this report for additional information on aircraft financing.

The Company has concluded its discussions with Boeing regarding certain contractual matters, including expected fuel burn, for current and future deliveries of certain Boeing 787 aircraft, and has reached a resolution with Boeing regarding compensation to be received in connection with those matters.

The table below summarizes the capital commitments of UAL and United (including those intended to be assigned from UAL) as of June 30, 2013, which primarily relate to the acquisition of aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets:

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company.

Aircraft Operating Leases and Capacity Purchase Agreements

In May 2013, United entered into a capacity purchase agreement with SkyWest Airlines, Inc. (“SkyWest”), a wholly-owned subsidiary of SkyWest, Inc., to operate 40 Embraer EMB175 aircraft under the United Express brand. SkyWest will purchase these 76-seat aircraft with deliveries in 2014 and 2015. These 40 aircraft are in addition to United’s April 2013 agreement to purchase 30 Embraer EMB175 aircraft, which will be operated by a different United Express carrier.

The table below summarizes the Company’s future payments through the end of the terms of our capacity purchase commitments, excluding variable pass-through costs such as fuel and landing fees, among others. In addition, the table below summarizes the Company’s scheduled future minimum lease payments under aircraft operating leases having initial or remaining noncancelable lease terms of more than one year and includes aircraft rent under capacity purchase agreements, including estimated commitments from the Embraer EMB175 aircraft which will be delivered starting in 2014.

Guarantees and Off-Balance Sheet Financing

Guarantees. United is the guarantor of approximately $1.9 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with $1.7 billion of these obligations are accounted for as operating leases with the associated expense recorded on a straight-line basis resulting in ratable accrual of the lease obligation over the expected lease term. The leasing arrangements associated with $180 million of these obligations are accounted for as capital leases. All these bonds are due between 2015 and 2038.

In the Company’s financing transactions that include loans, the Company typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans in which the interest rate is based on the London Interbank Offered Rate (“LIBOR”), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject in most cases to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2013, the Company had $2.0 billion of floating rate debt and $317 million of fixed rate debt, with remaining terms of up to nine years, that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to eight years and an aggregate balance of $2.2 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.

Credit Facilities. On March 27, 2013, United and UAL entered into a new Credit and Guaranty Agreement (the “Credit Agreement”) as the borrower and guarantor, respectively, that provides United with a $1.0 billion revolving credit facility. As of June 30, 2013, United had its entire capacity of $1.0 billion available under the revolving credit facility. See Note 9 of this report for more information.

25

Labor Negotiations. As of June 30, 2013, United had approximately 88,000 active employees, of whom approximately 80% were represented by various labor organizations. Having reached a ratified joint collective bargaining agreement with our pilots represented by the Air Line Pilots Association, International, we are currently in the process of negotiating joint collective bargaining agreements with our other major work groups, including our public contact co-workers, technicians, flight attendants and dispatchers.

NOTE 9—DEBT

As of June 30, 2013, a substantial portion of our assets are pledged as collateral for our debt. These assets principally consist of aircraft, route authorities and loyalty program intangible assets. As of June 30, 2013, the Company was in compliance with its debt covenants.

Unsecured 6.375% Senior Notes. In May 2013, UAL issued $300 million aggregate principal amount of 6.375% Senior Notes due June 1, 2018. The notes are fully and unconditionally guaranteed and recorded by United on its balance sheet as debt.

6% Convertible Senior Notes. During the second quarter of 2013, UAL issued approximately 22 million shares of UAL common stock pursuant to agreements that UAL entered into with certain of its securityholders in exchange for approximately $189 million in aggregate principal amount of UAL’s outstanding 6% convertible senior notes due 2029 held by such securityholders. See Note 3 of this report for more information.

2013 Credit and Guaranty Agreement. On March 27, 2013, United and UAL entered into the Credit Agreement as the borrower and guarantor, respectively. The Credit Agreement consists of a $900 million term loan due April 1, 2019 and a $1.0 billion revolving credit facility available for drawing until April 1, 2018. As of June 30, 2013, United had its entire capacity of $1.0 billion available under the revolving credit facility. The obligations of United under the Credit Agreement are secured by liens on certain international route authorities between certain specified cities, certain take-off and landing rights and related assets of United.

Borrowings under the Credit Agreement bear interest at a variable rate equal to LIBOR, subject to a 1% floor, plus a margin of 3.0% per annum, or another rate based on certain market interest rates, plus a margin of 2.0% per annum. The principal amount of the term loan must be repaid in consecutive quarterly installments of 0.25% of the original principal amount thereof, commencing on June 30, 2013, with any unpaid balance due on April 1, 2019. United may prepay all or a portion of the loan from time to time, at par plus accrued and unpaid interest. United pays a commitment fee equal to 0.75% per annum on the undrawn amount available under the revolving credit facility.

The Credit Agreement includes covenants that, among other things, require the Company to maintain at least $3.0 billion of unrestricted liquidity and a minimum ratio of appraised value of collateral to the outstanding obligations under the Credit Agreement of 1.67 to 1.0, and restrict the Company’s ability to incur additional indebtedness, issue preferred stock, make investments or pay dividends. The Credit Agreement contains events of default customary for this type of financing, including a cross default and cross acceleration provision to certain other material indebtedness of the Company. Under the provisions of the Credit Agreement, UAL’s ability to pay dividends on or repurchase UAL’s common stock is restricted.

United Amended Credit Facility. On March 27, 2013, the Company used $900 million from the Credit Agreement, together with approximately $300 million of cash to retire the entire principal balance of a $1.2 billion term loan due 2014 that was outstanding under United’s Amended and Restated Revolving Credit, Term Loan and Guaranty Agreement, dated as of February 2, 2007 (the “Amended Credit Facility”). The Amended Credit Facility was terminated concurrently with the repayment of the term loan.

$500 Million Revolving Credit Facility. On March 27, 2013, the Company terminated the $500 million revolving credit facility that it had previously entered into in December 2011. There were no outstanding borrowings under the revolving credit facility.

Debt Redemptions. On February 1, 2013, United redeemed all of the $400 million aggregate principal amount of its 9.875% Senior Secured Notes due 2013 and $200 million aggregate principal amount of 12.0% Senior Second Lien Notes due 2013. On February 8, 2013, United redeemed all $123 million aggregate principal amount of the B tranche of the 2006-1 EETC equipment notes due 2013. On April 1, 2013, United redeemed all of the $180 million aggregate principal amount of the senior tranche of the 2006-1 EETC equipment notes due 2013.

EETCs. In October 2012, United created two pass-through trusts, one of which issued $712 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4% and the second of which issued $132 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 5.5%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $844 million, are used to purchase equipment notes issued by United. Of the $844 million in proceeds raised by the pass-through trusts, United received $696 million as of June 30, 2013,

26

of which $202 million and $403 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trusts. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The proceeds have been and are expected to fund the acquisition of new aircraft.

In December 2012, United created one pass-through trust which issued $425 million aggregate principal amount of Class C pass-through certificates with a stated interest rate of 6.125%. The proceeds of the issuance of the Class C pass-through certificates are used to purchase equipment notes issued by United related to the aircraft financed in both the March and October 2012 EETC financings. Of the $425 million in proceeds raised by the pass-through trust, United received $385 million as of June 30, 2013, of which $53 million and $107 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trust. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates.

NOTE 10—SPECIAL ITEMS

Special Charges. For the three and six months ended June 30, special charges consisted of the following (in millions):

	Three Months Ended June 30,					Six Months Ended June 30,

Income tax benefit		—		—			—			(2	)
Total special charges, net of income taxes	$	52	$	206		$	144		$	368

Merger integration-related costs include compensation costs related to systems integration and training, costs to repaint aircraft and other branding activities, new uniforms, costs to write-off or accelerate depreciation on systems and facilities that are no longer used or planned to be used for significantly shorter periods, relocation costs for employees and severance primarily associated with administrative headcount reductions.

During the six months ended June 30, 2013, the Company recorded $14 million associated with a voluntary program offered by United in which flight attendants took an unpaid 13-month leave of absence. The flight attendants continue to receive medical benefits and other company benefits while on leave under this program. Approximately 1,300 flight attendants opted to participate in the program. In addition, the Company recorded $18 million associated with the temporary grounding of its Boeing 787 aircraft, $7 million of which was recorded during the second quarter of 2013. The charges are comprised of aircraft depreciation expense and dedicated personnel costs that the Company incurred while the aircraft were grounded. The aircraft returned to service in May 2013. Also, the Company recorded a $5 million gain related to a contract termination and $2 million in losses on the sale of assets.

27

During the three and six months ended June 30, 2012, the Company recorded $76 million and $125 million of severance and benefits associated with three voluntary employee programs, respectively. During the first quarter of 2012, approximately 400 mechanics offered to retire early in exchange for a cash severance payment that was based on the number of years of service each employee had accumulated. The Company also offered a voluntary leave of absence program that approximately 1,800 flight attendants accepted, which allows for continued medical coverage during the leave of absence period. During the second quarter of 2012, as part of the recently amended collective bargaining agreement with the Association of Flight Attendants, the Company offered a voluntary program for flight attendants at United to retire early in exchange for a cash severance payment. The payments are dependent on the number of years of service each employee has accumulated. Approximately 1,300 flight attendants accepted this program and the Company estimates the amount for this voluntary program to be approximately $76 million.

In March 2013, the Company agreed to sell up to 30 Boeing 757-200 aircraft to FedEx Corporation beginning in April 2013. As of December 31, 2012, the Company operated 133 such aircraft. Given the planned sale of up to 30 of these aircraft, the Company evaluated the entire fleet and determined that no impairment existed. However, the Company adjusted the salvage value of the aircraft designated for sale to its sales price and will record additional depreciation from the agreement date to the date of sale. This additional depreciation is not classified as special. The additional depreciation in the first six months of 2013 totaled $40 million and is estimated to be approximately $80 million for the full year 2013.

Accruals

The accrual for severance and medical costs was $38 million as of June 30, 2013, compared to $153 million as of June 30, 2012. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $3 million as of June 30, 2013, compared to $8 million as of June 30, 2012.

The severance-related accrual as of June 30, 2013 is expected to be paid through 2015. Lease payments for grounded aircraft are expected to continue through 2013.

Second Quarter Operational Highlights

• For the quarter ended June 30, 2013, United recorded a U.S. Department of Transportation on-time arrival rate of 75.6% and a system completion factor of 99.1%.

• Consolidated traffic and capacity decreased 1.7% and 2.1%, respectively, during the second quarter of 2013 as compared to the second quarter of 2012. The Company’s load factor for the second quarter of 2013 was 84.7%.

• The Company took delivery of six new Boeing 737-900ER aircraft during the second quarter of 2013.

Outlook

In order to generate sustained profitability over the business cycle, the Company manages its capacity to balance with expected demand for travel. For the first six months of 2013, consolidated capacity decreased 3.5% compared to the first six months of 2012. The Company expects full-year 2013 consolidated capacity to decrease 0.75% to 1.75% year-over-year, with full-year 2013 domestic capacity to decrease 0.8% to 1.8% and full-year 2013 international capacity to decrease 0.7% to 1.7%. The Company expects full year 2013 cost per available seat mile (“CASM”) excluding profit sharing, third-party business expense, fuel and special charges to increase 5.5% to 6.5% year-over-year.

RESULTS OF OPERATIONS

The following discussion provides an analysis of results of operations and reasons for material changes therein for the three and six months ended June 30, 2013 as compared to the corresponding periods in 2012.

Second Quarter 2013 Compared to Second Quarter 2012

The Company recorded net income of $469 million in the second quarter of 2013 as compared to net income of $339 million in the second quarter of 2012. Excluding special items, the Company had net income of $521 million in the second quarter of 2013 as compared to net income of $545 million in the second quarter of 2012. See “Reconciliation of GAAP to non-GAAP Financial Measures” at the end of this item for additional information related to accounting principles generally accepted in the United States (“GAAP”) to non-GAAP financial measures. We consider a key measure of our performance to be operating income, which was $770 million for the second quarter of 2013, as compared to $575 million for the second quarter of 2012. Significant components of our operating results for the three months ended June 30 are as follows (in millions, except percentage changes):

(a) See Item 6 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for the definition of these statistics.

Consolidated passenger revenue in the second quarter of 2013 decreased 1.1% as compared to the year-ago period due to a decline of 3.0% in the number of passengers flown year-over-year as a result of a reduction in capacity of 2.1%, offset in part by an increase in the consolidated average fare per passenger of 1.9%.

Cargo revenue decreased $29 million, or 10.9%, in the second quarter of 2013 as compared to the year-ago period due to lower volumes on freight and mail across all regions.

Other operating revenue in the second quarter of 2013 increased $191 million, or 21.1%, as compared to the year-ago period due primarily to the sale of aircraft fuel to a third party as well as other MileagePlus and marketing-related revenue.

Operating Expenses

The table below includes data related to the Company’s operating expenses for the three months ended June 30 (in millions, except for percentage changes):

	2013		2012		Increase (Decrease)			% Change

Other operating expenses		1,314		1,174		140			11.9
	$	9,231	$	9,364	$	(133	)		(1.4	)

Aircraft fuel expense decreased $340 million, or 10.0%, year-over-year due primarily to an 8.2% decrease in the average price per gallon of fuel and a 1.8% decrease in fuel consumption in the second quarter of 2013 as a result of reduced capacity. The table below presents the significant changes in aircraft fuel cost per gallon in the three month period ended June 30, 2013 as compared to the year-ago period:

33

	(In millions)									Average price per gallon
	2013			2012			% Change			2013			2012			% Change
Total aircraft fuel purchase cost excluding fuel hedge impacts	$	3,059		$	3,370			(9.2	)	$	3.01		$	3.26			(7.7	)

Fuel expense including all gains (losses) from settled hedges (b)	$	3,069		$	3,407			(9.9	)	$	3.02		$	3.29			(8.2	)
Total fuel consumption (gallons)		1,016			1,035			(1.8	)

(a) Includes ineffectiveness gains (losses) on settled hedges and gains (losses) on settled hedges that were not designated for hedge accounting. These amounts are recorded in Nonoperating income (expense): Miscellaneous, net.

(b) This figure does not include mark-to-market (“MTM”) gains or losses, which the Company records in Nonoperating income (expense): Miscellaneous, net. MTM losses were $81 million and $30 million for the three months ended June 30, 2013 and 2012, respectively.

Salaries and related costs increased $151 million, or 7.5%, in the second quarter of 2013 as compared to the year-ago period primarily due to a 0.7% increase in the number of employees, higher pay rates driven by new collective bargaining agreements as well as increased pension plan costs.

Aircraft maintenance materials and outside repairs increased $48 million, or 11.1%, in the second quarter of 2013 as compared to the year-ago period primarily due to United’s reliability improvement initiatives which increased volumes of airframe checks, engine overhauls, and aircraft modification projects.

Depreciation and amortization increased $47 million, or 12.4%, in the second quarter of 2013 as compared to the year-ago period due to additions in owned property and equipment in the current year, specifically related to aircraft and improvements at airport facilities, as well as accelerated depreciation on Boeing 757-200 aircraft in process of being sold to a third party.

Other operating expenses increased $140 million, or 11.9%, in the second quarter of 2013 as compared to the year-ago period primarily due to the cost of aircraft fuel sold to a third party and an increase in other personnel-related expenses.

Details of the Company’s special charges include the following for the three months ended June 30 (in millions):

	2013		2012
Merger integration-related costs	$	45	$	137
Additional costs associated with the temporarily grounded Boeing 787 aircraft		7		—
Voluntary severance and benefits		—		76
Gains on sale of assets and other special items, net		—		(7	)
Special charges	$	52	$	206

See Note 10 to the financial statements included in Part I, Item 1 of this report.

Nonoperating Income (Expense). The following table illustrates the year-over-year dollar and percentage changes in the Company’s nonoperating income (expense) for the three months ended June 30 (in millions, except for percentage changes):

34

	2013			2012			Increase (Decrease)			% Change
Interest expense	$	(194	)	$	(213	)	$	(19	)		(8.9	)
Interest capitalized		12			9			3			33.3
Interest income		6			7			(1	)		(14.3	)
Miscellaneous, net		(123	)		(38	)		85			NM
Total	$	(299	)	$	(235	)	$	64			27.2

Interest expense decreased $19 million, or 8.9%, in the second quarter of 2013, compared to the year-ago period primarily due to a decrease in debt outstanding during the second quarter of 2013 as compared to debt outstanding during the year-ago period.

During the second quarter of 2013, the fuel hedge ineffectiveness loss in miscellaneous, net was $1 million as compared to fuel hedge ineffectiveness loss of $29 million in the year-ago period. Second quarter 2013 miscellaneous, net also included loss of $81 million from derivatives not qualifying for hedge accounting.

United’s nonoperating expense also includes net loss of $8 million and net gain of $30 million for the three months ended June 30, 2013 and 2012, respectively, associated with marking to market the fair value of derivative assets and liabilities related to agreements that provide for United’s convertible debt to be settled with UAL common stock. This net gain/loss and related derivatives are reflected only in the United stand-alone financial statements as they are eliminated at the consolidated level. See Note 6 to the financial statements included in Part I, Item 1 of this report for additional information.

Income Taxes. Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because management has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. See Note 4 to the financial statements included in Part I, Item 1 of this report for information related to this matter.

First Six Months 2013 Compared to First Six Months 2012

UAL recorded net income of $52 million in the first six months of 2013 as compared to net loss of $109 million in the first six months of 2012. Excluding special items, UAL had net income of $196 million in the first six months of 2013 as compared to net income of $259 million in the first six months of 2012. See “Reconciliation of GAAP to non-GAAP Financial Measures” at the end of this item for additional information related to GAAP to non-GAAP financial measures. We consider a key measure of our performance to be operating income, which was $506 million for the first six months of 2013, as compared to $304 million for the first six months of 2012. Significant components of our operating results for the first six months of 2013 are as follows (in millions, except percentage changes):

Interest expense decreased $34 million, or 7.9%, in the first six months of 2013, compared to the year-ago period primarily due to a decrease in debt outstanding during the first six months of 2013 as compared to debt outstanding during the year-ago period.

During the first six months of 2013, miscellaneous, net included a fuel hedge ineffectiveness loss of $1 million as compared to loss of $4 million in the year-ago period. The first six months of 2013 miscellaneous, net also included loss of $31 million from derivatives not qualifying for hedge accounting as compared to zero in the year ago period.

United’s nonoperating expense also includes net gains of $56 million and $44 million for the six months ended June 30, 2013 and 2012, respectively, associated with marking to market the fair value of derivative assets and liabilities related to agreements that provide for United’s convertible debt to be settled with UAL common stock. This net gain and related derivatives are reflected only in the United stand-alone financial statements as they are eliminated at the consolidated level. See Note 6 to the financial statements included in Part I, Item 1 of this report for additional information.

Income Taxes. Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because management has concluded that it is more likely than not that such deferred tax assets will ultimately not be realized. See Note 4 to the financial statements contained in Part I, Item 1 of this report for information related to this matter.

LIQUIDITY AND CAPITAL RESOURCES

Current Liquidity

As of June 30, 2013, the Company had $6.0 billion in unrestricted cash, cash equivalents and short-term investments, as compared to $6.5 billion at December 31, 2012. At June 30, 2013, the Company also had $435 million of restricted cash and cash equivalents, which is primarily collateral for performance bonds, letters of credit, estimated future workers’ compensation claims and credit card processing agreements. As of June 30, 2013, the Company had its entire commitment capacity of $1.0 billion under the Credit Agreement available for letters of credit or borrowings.

38

As is the case with many of our principal competitors, we have a high proportion of debt compared to capital. We have a significant amount of fixed obligations, including debt, aircraft leases and financings, leases of airport property and other facilities, and pension funding obligations. At June 30, 2013, the Company had approximately $12.0 billion of debt and capital lease obligations, including $1.0 billion that will become due in the next 12 months. In addition, we have substantial non-cancelable commitments for capital expenditures, including the acquisition of new aircraft and related spare engines.

The Company will continue to evaluate opportunities to repurchase its debt in open market transactions to reduce its indebtedness and the amount of interest paid on its indebtedness.

On April 29, 2013, United entered into an agreement to purchase 30 Embraer EMB175 regional jets, scheduled for delivery in 2014 and 2015.

On June 17, 2013, United entered into supplemental agreements to United’s 787 aircraft purchase agreements with The Boeing Company (“Boeing”) to add to its existing firm order of Boeing 787 widebody aircraft ten Boeing 787-10 aircraft, convert an existing firm order for ten Boeing 787 aircraft into Boeing 787-10 aircraft and make certain other changes to those agreements. On June 19, 2013, United entered into amendments to its A350 purchase agreement with Airbus S.A.S. (“Airbus”) to add to its existing firm order of Airbus A350 widebody aircraft ten Airbus A350-1000 aircraft, convert its existing firm order for 25 Airbus A350-900 aircraft into Airbus A350-1000 aircraft and make certain other changes to the agreement. The Company expects to take delivery of the Boeing 787-10 aircraft and Airbus A350-1000 aircraft between 2018 and 2024.

As of June 30, 2013, UAL had firm commitments to purchase 100 new Boeing 737 MAX 9 aircraft scheduled for delivery from 2018 through 2025. UAL also had options to purchase additional Boeing 737 MAX 9 aircraft. UAL intends in the future to assign its interest under the purchase agreement for the 737 MAX 9 aircraft to United.

As of June 30, 2013, United had firm commitments to purchase 199 new aircraft (59 Boeing 787 aircraft, 75 Boeing 737 aircraft, 35 Airbus A350-1000 aircraft, and 30 Embraer EMB175 aircraft) scheduled for delivery from July 1, 2013 through 2025. United also had options and purchase rights for additional aircraft. In the second quarter of 2013, United took delivery of six Boeing 737-900ER. In the remainder of 2013, United expects to take delivery of twelve Boeing 737-900ER aircraft and two Boeing 787-8 aircraft.

United had arranged for EETC financing of 14 Boeing 737-900ER aircraft, six of which were delivered during the second quarter of 2013 and two of which are scheduled to be delivered during the remainder of 2013. United also has arranged for EETC financing of one Boeing 787-8 aircraft and a bank debt financing commitment for one Boeing 737-900ER aircraft scheduled for delivery in the second half of 2013. In addition, United had secured backstop financing commitments from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. However, the Company does not have backstop financing or any financing currently in place for its other firm aircraft orders. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all. See Note 9 to the financial statements included in Part I, Item 1 of this report for additional information on aircraft financing.

As of June 30, 2013, UAL and United (including those intended to be assigned from UAL) have total capital commitments primarily related to the acquisition of aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets of approximately $23.5 billion, of which approximately $1.2 billion, $2.5 billion, $2.0 billion, $2.4 billion, $1.4 billion and $14.0 billion are due in the last six months of 2013 and for the full year for 2014, 2015, 2016, 2017 and thereafter, respectively.

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company.

The Company has concluded its discussions with Boeing regarding certain contractual matters, including expected fuel burn, for current and future deliveries of certain Boeing 787 aircraft, and has reached a resolution with Boeing regarding compensation to be received in connection with those matters.

As of June 30, 2013, a substantial portion of the Company’s assets, principally aircraft, route authorities and certain other intangible assets, were pledged under various loan and other agreements. We must sustain our profitability and/or access the capital markets to meet our significant long-term debt and capital lease obligations and future commitments for capital expenditures, including the acquisition of aircraft and related spare engines.

In May 2013, United entered into a capacity purchase agreement with SkyWest Airlines, Inc. (“SkyWest”), a wholly-owned subsidiary of SkyWest, Inc., to operate 40 Embraer EMB175 aircraft under the United Express brand. SkyWest will purchase these 76-seat aircraft with deliveries in 2014 and 2015. These 40 aircraft are in addition to United’s April 2013 agreement to purchase 30 Embraer EMB175 aircraft, which will be operated by a different United Express carrier. See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information.

39

In April 2013, United signed a 20-year lease extension with the Port Authority of New York and New Jersey to continue its use of Terminal C1 and C2 at Newark Liberty International Airport (“Newark”). United also committed to invest an additional $150 million in facility upgrades at Newark to enhance the customer experience and efficiency of the operation. See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information.

Credit Ratings. As of the filing date of this report, UAL and United had the following corporate credit ratings:

	S&P	Moody’s	Fitch
UAL	B	B2	B
United	B	*	B

* The credit agency does not issue corporate credit ratings for subsidiary entities.

These credit ratings are below investment grade levels. Downgrades from these rating levels, among other things, could restrict the availability, or increase the cost of future financing for the Company.

Sources and Uses of Cash

Operating Activities. Cash flow provided by operations for the six months ended June 30, 2013 was $1.5 billion compared to $1.1 billion in the same period in 2012. The increase is attributable to an increase in operating income and a change in certain other working capital items, including a decrease in receivables.

Investing Activities. Capital expenditures, including aircraft purchase deposits, were $821 million and $619 million in the six months ended June 30, 2013 and 2012, respectively. Capital expenditures for the six months ended June 30, 2013 were primarily attributable to the purchase of aircraft, facility and fleet-related costs and certain other information technology projects.

In addition to capital expenditures during the six months ended June 30, 2013, we acquired six aircraft through the issuance of debt. See “Financing Activities” below for additional information.

The purchase of short-term investments decreased to $41 million in the six months ended June 30, 2013 from $96 million in the six months ended June 30, 2012.

Financing Activities. During the six months ended June 30, 2013, the Company made debt and capital lease payments of $1.8 billion.

During the second quarter of 2013, UAL issued approximately 22 million shares of UAL common stock pursuant to agreements that UAL entered into with certain of its securityholders in exchange for approximately $189 million in aggregate principal amount of UAL’s outstanding 6% convertible senior notes due 2029 held by such securityholders. The newly issued shares of UAL common stock are included in the determination of basic weighted average shares outstanding for the three and six months ended June 30, 2013. The Company retired the 6% convertible senior notes acquired in the exchange.

In May 2013, UAL issued $300 million aggregate principal amount of 6.375% Senior Notes due June 1, 2018. The notes are fully and unconditionally guaranteed and recorded by United on its balance sheet as debt.

On March 27, 2013, United and UAL entered into a new Credit and Guaranty Agreement (the “Credit Agreement”) as the borrower and guarantor, respectively. The Credit Agreement consists of a $900 million term loan due April 1, 2019 and a $1.0 billion revolving credit facility available for drawing until April 1, 2018. As of June 30, 2013, United had its entire capacity of $1.0 billion available under the revolving credit facility. The obligations of United under the Credit Agreement are secured by liens on certain international route authorities between certain specified cities, certain take-off and landing rights and related assets of United.

Borrowings under the Credit Agreement bear interest at a variable rate equal to LIBOR, subject to a 1% floor, plus a margin of 3.0% per annum, or another rate based on certain market interest rates, plus a margin of 2.0% per annum. The principal amount of the term loan must be repaid in consecutive quarterly installments of 0.25% of the original principal amount thereof, commencing on June 30, 2013, with any unpaid balance due on April 1, 2019. United may prepay all or a portion of the loan from time to time, at par plus accrued and unpaid interest. United pays a commitment fee equal to 0.75% per annum on the undrawn amount available under the revolving credit facility. Certain covenants in the Credit Agreement are summarized in Note 9 to the financial statements included in Part I, Item 1 of this report. Under the provisions of the Credit Agreement, UAL’s ability to pay dividends on or repurchase UAL’s common stock is restricted.

40

On March 27, 2013, the Company used $900 million from the Credit Agreement, together with approximately $300 million of cash to retire the entire principal balance of a $1.2 billion term loan due 2014 that was outstanding under United’s Amended and Restated Revolving Credit, Term Loan and Guaranty Agreement, dated as of February 2, 2007 (the “Amended Credit Facility”). The Amended Credit Facility was terminated concurrently with the repayment of the term loan. The Company also terminated the $500 million revolving credit facility that it had previously entered into in December 2011. There were no outstanding borrowings under the revolving credit facility.

On February 1, 2013, United redeemed all of the $400 million aggregate principal amount of its 9.875% Senior Secured Notes due 2013 and $200 million aggregate principal amount of 12.0% Senior Second Lien Notes due 2013. On February 8, 2013, United redeemed all $123 million aggregate principal amount of the B tranche of the 2006-1 EETC equipment notes due 2013. On April 1, 2013, United redeemed all of the $180 million aggregate principal amount of the senior tranche of the 2006-1 EETC equipment notes due 2013.

In October 2012, United created two pass-through trusts, one of which issued $712 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4% and the second of which issued $132 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 5.5%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $844 million, are used to purchase equipment notes issued by United. Of the $844 million in proceeds raised by the pass-through trusts, United received $696 million as of June 30, 2013, of which $202 million and $403 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trusts. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The proceeds have been and are expected to fund the acquisition of new aircraft.

In December 2012, United created one pass-through trust which issued $425 million aggregate principal amount of Class C pass-through certificates with a stated interest rate of 6.125%. The proceeds of the issuance of the Class C pass-through certificates are used to purchase equipment notes issued by United related to the aircraft financed in both the March and October 2012 EETC financings. Of the $425 million in proceeds raised by the pass-through trust, United received $385 million as of June 30, 2013, of which $53 million and $107 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trust. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates.

Commitments, Contingencies and Liquidity Matters

As described in the 2012 Annual Report, the Company’s liquidity may be adversely impacted by a variety of factors, including, but not limited to, obligations associated with fuel hedge settlements and related collateral requirements, pension funding obligations, reserve requirements associated with credit card processing agreements, guarantees, commitments and contingencies. See the 2012 Annual Report and Notes 5, 7, 8 and 9 to the financial statements contained in Part I, Item 1 of this report for information related to these matters.

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

The Company evaluates its financial performance utilizing various GAAP and non-GAAP financial measures, including net income/loss and net earnings/loss per share. The non-GAAP financial measures in this report are presented because they provide management and investors the ability to measure and monitor the Company’s performance on a consistent basis. The Company believes that adjusting for special charges is useful to investors because they are non-recurring items not indicative of the Company’s on-going performance. A reconciliation of net income (loss) and diluted earnings (loss) per share to the non-GAAP financial measure of net income and diluted earnings per share, excluding special charges, for the three and six months ended June 30 is as follows (in millions, except per share amounts):

41

	Three Months Ended June 30,								Six Months Ended June 30,
	Net Income		Diluted Earnings per Share		Net Income		Diluted Earnings per Share		Net Income		Diluted Earnings per Share		Net Income (Loss)			Diluted Earnings (Loss) per Share
	2013		2013		2012		2012		2013		2013		2012			2012
Net income (loss) — GAAP	$	469	$	1.21	$	339	$	0.89	$	52	$	0.15	$	(109	)	$	(0.33	)

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

There have been no material changes in market risk from the information provided in Item 7A. “Quantitative and Qualitative Disclosures About Market Risk” in our 2012 Annual Report except as follows:

Aircraft Fuel. As of June 30, 2013, the Company had hedged approximately 47% and 18% of its projected fuel requirements (942 million and 706 million gallons, respectively) for 2013 and 2014, respectively, with commonly used financial hedge instruments based on aircraft fuel or closely related commodities, such as heating oil, diesel fuel and crude oil. As of June 30, 2013, the Company had fuel hedges expiring through December 2014.

At June 30, 2013, fuel derivatives were in a net liability position of $23 million. See Note 7 to the financial statements included in Part I, Item 1 of this report for additional information related to fuel hedges.

ITEM 4. CONTROLS AND PROCEDURES.

The Company maintains controls and procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted to the SEC is recorded, processed, summarized and reported, within the time periods specified by the SEC’s rules and forms, and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. The Company’s management, including the Chief Executive Officer and Chief Financial Officer, performed an evaluation to conclude with reasonable assurance that UAL’s and United’s disclosure controls and procedures were designed and operating effectively to report the information each company is required to disclose in the reports they file with the SEC on a timely basis. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer of UAL and United have concluded that as of June 30, 2013, disclosure controls and procedures of each of UAL and United were effective.

Changes in Internal Control over Financial Reporting during the Quarter Ended June 30, 2013

During the three months ended June 30, 2013, there were no changes in UAL’s or United’s internal controls over financial reporting that materially affected, or are reasonably likely to materially affect, their internal controls over financial reporting (as defined in rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

43

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

See Part I, Item 3., “Legal Proceedings” of the 2012 Annual Report for a description of legal proceedings. The disclosure below includes updates to the legal proceedings disclosures included in the 2012 Annual Report, which are in addition to, and not in lieu of, those disclosures contained in the 2012 Annual Report.

Litigation Associated with September 11, 2001 Terrorism

Families of 94 victims of the September 11, 2001, terrorist attacks filed lawsuits asserting a variety of claims against the airline industry. United and American Airlines (the “aviation defendants”), as the two carriers whose flights were hijacked on September 11, 2001, are the central focus of the litigation, but a variety of additional parties, including Continental Airlines, Inc. (“Continental”), have been sued on a number of legal theories ranging from collective responsibility for airport screening and security systems that allegedly failed to prevent the attacks to faulty design and construction of the World Trade Center towers. World Trade Center Properties, Inc., as lessee, also filed claims against the aviation defendants and The Port Authority of New York and New Jersey (the “Port Authority”), the owner of the World Trade Center, for property and business interruption damages. The Port Authority has also filed cross-claims against the aviation defendants in both the wrongful death litigation and for property damage sustained in the attacks. The insurers of various tenants at the World Trade Center filed subrogation claims for damages as well. By statute, these matters were consolidated in the U.S. District Court for the Southern District of New York and the aviation defendants’ exposure was capped at the limit of the liability coverage maintained by each carrier at the time of the attacks. In September 2011, United settled the last remaining wrongful death claim in connection with this matter. In 2010, insurers for the aviation defendants reached a settlement with all of the subrogated insurers and most of the uninsured plaintiffs with property and business interruption claims, which was approved by the court and has been affirmed by the U.S. Court of Appeals for the Second Circuit. The U.S. District Court for the Southern District of New York dismissed a claim for environmental cleanup damages filed by a neighboring property owner, Cedar & Washington Associates, LLC. This dismissal order has been appealed to the U.S. Court of Appeals for the Second Circuit. In January 2013, Continental was dismissed from the litigation in its entirety. On July 18, 2013, after a four day hearing, the U.S. District Court for the Southern District of New York ruled that World Trade Center Properties, Inc.’s claims against the aviation defendants would be dismissed, holding that previous insurance recoveries by World Trade Center Properties, Inc. precluded it from seeking damages in tort against the aviation defendants. World Trade Center Properties, Inc. stated it will appeal the ruling to the U.S. Court of Appeals for the Second Circuit. In the aggregate, claims related to the events of September 11, 2001 are estimated to be well in excess of $10 billion. The Company believes that it will have no financial exposure for claims arising out of the events of September 11, 2001 in light of the provisions of the Air Transportation Safety and System Stabilization Act of 2001 limiting claimants’ recoveries to insurance proceeds, the resolution of the wrongful death and personal injury cases by settlement, the resolution of the majority of the property damage claims and the withdrawal of all related proofs of claim from UAL Corporation’s Chapter 11 bankruptcy proceeding.

EEOC Claim Under the Americans with Disabilities Act

On June 5, 2009, the U.S. Equal Employment Opportunity Commission (“EEOC”) filed a lawsuit on behalf of five named individuals and other similarly situated employees alleging that United’s reasonable accommodation policy for employees with medical restrictions does not comply with the requirements of the Americans with Disabilities Act. The EEOC maintains that qualified disabled employees should be placed into available open positions for which they are minimally qualified, even if there are better qualified candidates for these positions. Under United’s accommodation policy, employees who are medically restricted and who cannot be accommodated in their current position are given the opportunity to apply and compete for available positions. If the medically restricted employee is similarly qualified to others who are competing for an open position, under United’s policy, the medically restricted employee will be given a preference for the position. If, however, there are candidates that have superior qualifications competing for an open position, then no preference will be given. United successfully transferred the venue of the case to the United States Federal Court for the Northern District of Illinois. Following the district court’s dismissal of the matter and the EEOC’s subsequent appeal to the Seventh Circuit Court of Appeals, on September 7, 2012, the Seventh Circuit overruled previous precedent and held that there may be an obligation to place a minimally qualified disabled worker in a position over a more qualified non-disabled worker. After the case was remanded to district court and the district court’s grant of United’s motion to stay this mandate during appeal, United filed a Petition for Certiorari with the Supreme Court of the United States (the “Supreme Court”) on December 5, 2012. On May 28, 2013, the Supreme Court rejected United’s Petition for Certiorari and remanded the case back to the district court for further litigation.

ITEM 1A. RISK FACTORS.

See Part I, Item 1A., “Risk Factors,” of the 2012 Annual Report and Part II, Item 1A., “Risk Factors” of the Company’s Form 10-Q for the quarter ended March 31, 2013 (the “First Quarter 2013 Form 10-Q”) for a detailed discussion of the risk factors affecting UAL and United. The disclosure below includes updates to certain risk factor disclosures included in the 2012 Annual Report, which are in addition to, and not in lieu of, those disclosures contained in the 2012 Annual Report and the First Quarter 2013 Form 10-Q.

Extensive government regulation could increase the Company’s operating costs and restrict its ability to conduct its business.

Airlines are subject to extensive regulatory and legal oversight. Compliance with U.S. and international regulations imposes significant costs and may have adverse effects on the Company. Laws, regulations, taxes and airport rates and charges, both domestically and internationally, have been proposed from time to time that could significantly increase the cost of airline operations or reduce airline revenue. The Company cannot provide any assurance that current laws and regulations, or laws or regulations enacted in the future, will not adversely affect its financial condition or results of operations.

United provides air transportation under certificates of public convenience and necessity issued by the U.S. Department of Transportation (the “DOT”). If the DOT altered, amended, modified, suspended or revoked these certificates, it could have a material adverse effect on the Company’s business. The DOT is also responsible for promulgating consumer protection and other regulations that may impose significant compliance costs on the Company. The Federal Aviation Administration (“FAA”) regulates the safety of United’s operations. United operates pursuant to an air carrier operating certificate issued by the FAA. From time to time, the FAA also issues orders, airworthiness directives and other regulations relating to the maintenance and operation of aircraft that require material expenditures or operational restrictions by the Company. These FAA orders and directives could include the temporary grounding of an entire aircraft type if the FAA identifies design, manufacturing, maintenance or other issues requiring immediate corrective action. For example, in January 2013, the FAA announced a review of the Boeing 787 aircraft’s critical systems and in-service issues and issued an emergency airworthiness directive that required U.S. Boeing 787 operators, including the Company, to temporarily cease operations of such aircraft. In April 2013, the FAA approved Boeing’s design modifications to the Boeing 787 battery system and provided clearance to U.S. Boeing 787 operators to resume operations of the aircraft, subject to operators retrofitting the aircraft with modified battery systems. The Company resumed commercial flights of its Boeing 787 aircraft on May 20, 2013. FAA requirements cover, among other things, retirement of older aircraft, security measures, collision avoidance systems, airborne windshear avoidance systems, noise abatement and other environmental concerns, aircraft operation and safety and increased inspections and maintenance procedures to be conducted on older aircraft. These FAA directives or requirements could have a material adverse effect on the Company.

In addition, the Company’s operations may be adversely impacted due to the existing antiquated air traffic control (“ATC”) system utilized by the U.S. government. During peak travel periods in certain markets, the current ATC system’s inability to handle existing travel demand has led to short-term capacity constraints imposed by government agencies and resulted in delays and disruptions of air traffic. In addition, the current system will not be able to effectively handle projected future air traffic growth. Imposition of these ATC constraints on a long-term basis may have a material adverse effect on our results of operations. Failure to update the ATC system in a timely manner, and the substantial funding requirements of a modernized ATC system that may be imposed on air carriers may have an adverse impact on the Company’s financial condition or results of operations.

The airline industry is subject to extensive federal, state and local taxes and fees that increase the cost of the Company’s operations. In addition to taxes and fees that the Company is currently subject to, proposed taxes and fees are currently pending and if imposed, would increase the Company’s operating expenses.

Access to landing and take-off rights, or “slots,” at several major U.S. airports and many foreign airports served by the Company are, or recently have been, subject to government regulation. Certain of the Company’s major hubs are among increasingly congested airports in the United States and have been or could be the subject of regulatory action that might limit the number of flights and/or increase costs of operations at certain times or throughout the day. The FAA may limit the Company’s airport access by limiting the number of departure and arrival slots at high density traffic airports, which could affect the Company’s ownership and transfer rights, and local airport authorities may have the ability to control access to certain facilities or the cost of access to its facilities, which could have an adverse effect on the Company’s business. The FAA historically has taken actions with respect to airlines’ slot holdings that airlines have challenged; if the FAA were to take actions that adversely affect the Company’s slot holdings, the Company could incur substantial costs to preserve its slots. Further, the Company’s operating costs at airports at which it operates, including the Company’s major hubs, may increase significantly because of capital improvements at such airports that the Company may be required to fund, directly or indirectly. In some circumstances, such costs could be imposed by the relevant airport authority without the Company’s approval and may have a material adverse effect on the Company’s financial condition.

The ability of carriers to operate flights on international routes between airports in the U.S. and other countries may be subject to change. Applicable arrangements between the United States and foreign governments may be amended from time to time, government policies with respect to airport operations may be revised, and the availability of appropriate slots or facilities may change. The Company currently operates a number of flights on international routes under government arrangements,

45

regulations or policies that designate the number of carriers permitted to operate on such routes, the capacity of the carriers providing services on such routes, the airports at which carriers may operate international flights, or the number of carriers allowed access to particular airports. Any further limitations, additions or modifications to such arrangements, regulations or policies could have a material adverse effect on the Company’s financial position and results of operations. Additionally, a change in law, regulation or policy for any of the Company’s international routes, such as open skies, could have a material adverse impact on the Company’s financial position and results of operations and could result in the impairment of material amounts of related tangible and intangible assets. In addition, competition from revenue-sharing joint ventures and other alliance arrangements by and among other airlines could impair the value of the Company’s business and assets on the open skies routes. The Company’s plans to enter into or expand U.S. antitrust immunized alliances and joint ventures on various international routes are subject to receipt of approvals from applicable U.S. federal authorities and obtaining other applicable foreign government clearances or satisfying the necessary applicable regulatory requirements. There can be no assurance that such approvals and clearances will be granted or will continue in effect upon further regulatory review or that changes in regulatory requirements or standards can be satisfied.

Many aspects of the Company’s operations are also subject to increasingly stringent federal, state, local and international laws protecting the environment. Future environmental regulatory developments, such as climate change regulations in the United States and abroad could adversely affect operations and increase operating costs in the airline industry. There are certain climate change laws and regulations that have already gone into effect and that apply to the Company, including the European Union Emissions Trading Scheme (which is subject to international dispute), the State of California’s cap and trade regulations, environmental taxes for certain international flights, limited greenhouse gas reporting requirements and land-use planning laws which could apply to airports and could affect airlines in certain circumstances. In addition, there is the potential for additional regulatory actions in regard to the emission of greenhouse gases by the aviation industry. The precise nature of future requirements and their applicability to the Company are difficult to predict, but the financial impact to the Company and the aviation industry would likely be adverse and could be significant.

The Company’s business and operations may also be impacted by the Budget Control Act of 2011 and related sequestration procedures of federal agencies. In April 2013, the FAA announced the implementation of furloughs of air traffic controllers through its capacity reduction plan, resulting in flight delays throughout the United States, including to the Company’s flights, until the U.S. Congress passed a bill suspending such furloughs. There can be no assurance that future sequestration obligations under the Budget Control Act of 2011 by the FAA, the Transportation Security Administration, the U.S. Customs and Border Protection or other federal agencies will not occur in future periods, potentially resulting in a material adverse impact on the Company.

See Item 1, Business-Industry Regulation, of the 2012 Annual Report for further information on government regulation impacting the Company.

Stockholders’ Meetings

2.1 Annual Meeting. A meeting of Stockholders shall be held annually for the election of Directors and the transaction of other business at an hour and date as shall be determined by the Board and designated in the notice of meeting.

2.2 Special Meetings.

(a) A special meeting of the Stockholders may be called by (i) both the Chief Executive Officer and the Chairman or (ii) the Board, and at an hour and date as shall be determined by them.

(b) Subject to this Section 2.2 and other applicable provisions of these Restated Bylaws, a special meeting of Stockholders shall be called by the Secretary upon the written request (each such request, a “Special Meeting Request” and such meeting, a “Stockholder Requested Special Meeting”) of one or more Stockholders of record of the Corporation that together have continuously held, for their own account or on behalf of others, beneficial ownership of at least a twenty-five percent (25%) aggregate “net long position” of the outstanding Common Stock (the “Requisite Percentage”) for at least one year prior to the date such request is delivered to the Corporation (such period, the “One-Year Period”). For purposes of determining the Requisite Percentage, “net long position” shall be determined with respect to each requesting holder in accordance with the definition thereof set forth in Rule 14e-4 under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (as so amended and inclusive of such rules and regulations, the “Exchange Act”); provided that (x) for purposes of such definition, (A) “the date that a tender offer is first publicly announced or otherwise made known by the bidder to the holders of the security to be acquired” shall be the date of the relevant Special Meeting Request, (B) the “highest tender offer price or stated amount of the consideration offered for the subject security” shall refer to the closing sales price of Common Stock on the New York Stock Exchange (or any successor thereto) on such date (or, if such date is not a trading day, the next succeeding trading day), (C) the “person whose securities are the subject of the offer” shall refer to the Corporation, and (D) a “subject security” shall refer to the outstanding Common Stock; and (y) the net long position of such holder shall be reduced by the number of shares of Common Stock as to which such holder does not, or will not, have the right to vote or direct the vote at the Stockholder Requested Special Meeting or as to which such holder has, at any time during the One-Year Period, entered into any derivative or other agreement, arrangement or understanding that hedges or transfers, in whole or in part, directly or indirectly, any of the economic consequences of ownership of such shares and which derivative or other agreement, arrangement or understanding remains in effect. Whether the requesting holders have submitted valid Special Meeting Requests representing the Requisite Percentage and complying with the requirements of this Section 2.2 and related provisions of these Restated Bylaws (a “Valid Special Meeting Request”) shall be determined in good faith by the Board, which determination shall be conclusive and binding on the Corporation and the Stockholders.

(c) In order for a Stockholder Requested Special Meeting to be called, one or more Special Meeting Requests must be signed by the Requisite Percentage of Stockholders submitting such request and by each of the beneficial owners, if any, on whose behalf the Special Meeting Request is being made and must be delivered to the Secretary. The Special Meeting Request(s) shall be delivered to the Secretary at the principal executive offices of the Corporation by nationally recognized private overnight courier service, return receipt requested. Each Special Meeting Request shall (i) set forth a statement of the specific purpose(s) of the requested special meeting and the matters proposed to be acted on at it, (ii) bear the date of signature of each such Stockholder signing the Special Meeting Request, (iii) set forth (A) the

name and address, as they appear in the Corporation’s books, of each Stockholder signing such request and the beneficial owners, if any, on whose behalf such request is made and (B) the class or series and number of shares of capital stock of the Corporation that are, directly or indirectly, owned of record or beneficially (within the meaning of Rule 13d-3 under the Exchange Act) by each such Stockholder and the beneficial owners, if any, on whose behalf such request is made, (iv) set forth any material interest of each Stockholder signing the Special Meeting Request in the business desired to be brought before the special meeting, (v) include documentary evidence that the Stockholders requesting the special meeting own the Requisite Percentage as of the date on which the Special Meeting Request is delivered to the Secretary of the Corporation; provided, however, that if the Stockholders are not the beneficial owners of the shares constituting all or part of the Requisite Percentage, then to be valid, the Special Meeting Request must also include documentary evidence (or, if not simultaneously provided with the Special Meeting Request, such documentary evidence must be delivered to the Secretary of the Corporation within ten (10) days after the date on which the Special Meeting Request is delivered to the Secretary of the Corporation) that the beneficial owners on whose behalf the Special Meeting Request is made beneficially own such shares as of the date on which such Special Meeting Request is delivered to the Secretary, (vi) an agreement by each of the Stockholders requesting the special meeting and each beneficial owner, if any, on whose behalf the Special Meeting Request is being made to notify the Corporation promptly in the event of any decrease in the net long position held by such Stockholder or beneficial owner following the delivery of such Special Meeting Request and prior to the Stockholder Requested Special Meeting and an acknowledgement that any such decrease shall be deemed to be a revocation of such Special Meeting Request by such Stockholder or beneficial owner to the extent of such reduction, (vii) contain any other information that would be a Disclosable Interest, as defined in Section 2.10(a)(3)(B)(vi) of these Restated Bylaws, if such Stockholder or beneficial owner, as applicable, were a Proposing Person, as defined in Section 2.10(a)(2) of these Restated Bylaws and (viii) if the purpose of the Stockholder Requested Special Meeting includes the election of one or more Directors, contain any other information that would be required to be set forth set forth with respect to a proposed nominee pursuant to Section 2.10(a)(3)(C) of these Restated Bylaws. Each Stockholder making a Special Meeting Request and each beneficial owner, if any, on whose behalf the Special Meeting Request is being made is required to update such Special Meeting Request delivered pursuant to this Section 2.2 in accordance with the requirements of Section 2.10(a)(4) of these Restated Bylaws. Any requesting Stockholder may revoke his, her or its Special Meeting Request at any time prior to the Stockholder Requested Special Meeting by written revocation delivered to the Secretary of the Corporation at the principal executive offices of the Corporation. There shall be no requirement to hold a special meeting (and the Board may cancel the special meeting) if the unrevoked (taking into account any specific written revocation or any reduction in the net long position held by such Stockholder, as described above) Special Meeting Requests represent in the aggregate less than the Requisite Percentage at any time after (a) a Valid Special Meeting Request has been delivered to the Secretary of the Corporation or (b) sixty (60) days following the earliest dated Special Meeting Request.

(d) In determining whether Special Meeting Requests have met the requirements of this Section 2.2, multiple Special Meeting Requests will be considered together only if (i) each Special Meeting Request identifies substantially the same purpose or purposes of the requested special meeting and substantially the same matters proposed to be acted on at the Stockholder Requested Special Meeting (in each case as determined in good faith by the Board), and (ii) such Special Meeting Requests have been delivered to the Secretary within 60 days of the delivery to the Secretary of the earliest dated Special Meeting Request relating to such item(s) of business.

(e) If none of the Stockholders who submitted a Special Meeting Request appears or sends a qualified representative to present the item of business submitted by the Stockholders for consideration at the Stockholder Requested Special Meeting, such item of business shall not be submitted for vote of the Stockholders at such Stockholder Requested Special Meeting, notwithstanding that proxies in respect of such vote may have been received by the Corporation or such Stockholder(s). A Special Meeting Request shall not be valid (and the Board shall have no obligation to call a special meeting in respect of such Special Meeting Request) if it relates to an item of business that is not a proper subject for Stockholder action under applicable law, was made in a manner that involved a violation of an applicable law or regulation, would violate the law, would cause the Corporation to violate the law or does not comply with the provisions of this Section 2.2. The procedures set forth in this Section 2.2 are the exclusive means by which items of business may be raised by Stockholders at a Stockholder Requested Special Meeting.

(f) Except as provided in the next sentence, a Stockholder Requested Special Meeting shall be held at such date, time and place within or without the State of Delaware as may be fixed by the Board; provided, however, that the date of any such Stockholder Requested Special Meeting shall be not more than ninety (90) days after the date on which a Valid Special Meeting Request has been delivered to the Secretary of the Corporation (such date of delivery being the “Delivery Date”). Notwithstanding the foregoing, a Stockholder Requested Special Meeting need not be held if (i) the Board has called or calls a meeting of Stockholders to be held within 90 days after the Delivery Date and the business of such meeting includes (among any other matters properly brought forth before the meeting) an item of business that is identical or substantially similar (as determined in good faith by the Board, a “Similar Item”) to an item of business specified in the Special Meeting Request or Requests, (ii) the Delivery Date is during the period commencing ninety (90) days prior to the first anniversary of the date of the immediately preceding annual meeting and ending on the earlier of (A) the date of the next annual meeting and (B) thirty (30) days after the first anniversary of the date of the immediately preceding annual meeting, or (iii) the subject of such Special Meeting Request or Requests contains a Similar Item to an item of business that was voted on at any meeting of Stockholders held within 120 days prior to the Delivery Date (it being understood that, for purposes of this Section 2.2, the election or removal of directors shall be deemed a Similar Item with respect to all items involving the election or removal of directors).

Written notice of a special meeting stating the place, date and hour of the meeting, the means of remote communications, if any, by which Stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and the purpose or purposes for which the meeting is called shall be given not less than ten nor more than sixty days before the date of the meeting to each Stockholder entitled to vote at such meeting.

Any notice relating to a special meeting appropriately called pursuant to this Section 2.2 shall describe the item or items of business to be considered at such special meeting. Business transacted at any special meeting shall be limited to the matters identified in the Corporation’s notice given pursuant to Section 2.4; provided, however, that nothing herein shall prohibit the Board from including in such notice and submitting to the Stockholders additional matters to be considered at any Stockholder Requested Special Meeting.

2.3 Place of Meetings. All meetings of Stockholders shall be held at such places, within or without the State of Delaware, as may from time to time be fixed by the Board or as specified or fixed in the respective notices. The Board may, in its sole discretion, determine that a meeting of the Stockholders shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211(a)(2) of the DGCL (or any successor provision thereto). Any previously-scheduled meeting of the Stockholders may be postponed by action of the Board taken prior to the time previously scheduled for such annual meeting of Stockholders.

2.4 Notices of Stockholders’ Meetings. Except as otherwise provided in Section 2.5 or otherwise required by the Restated Certificate or applicable law, written notice of each meeting of Stockholders, whether annual or special, shall be given to each Stockholder required or permitted to take any action at, or entitled to notice of, such meeting not less than ten (10) nor more than sixty (60) days before the date on which the meeting is to be held, by delivering such notice to him or her, personally, by mail or by electronic transmission in the manner provided by law. If mailed, such notice shall be deemed to be given when deposited in the United States mail, with postage prepaid, directed to the Stockholder at his or her address as it appears on the stock ledger of the Corporation. Every notice of a meeting of Stockholders shall state the place, date and hour of the meeting and the purpose or purposes for which the meeting is called.

2.5 Waivers of Notice. Notwithstanding any other provision in these Restated Bylaws, notice of any meeting of Stockholders shall not be required as to any Stockholder who shall attend such meeting in person or be represented by proxy, except when such Stockholder attends such meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business at such meeting because the meeting is not lawfully called or convened. If any Stockholder shall, in person or represented by proxy, waive notice of any meeting, whether before or after such meeting, notice thereof shall not be required as to such Stockholder.

2.6 Quorum Requirements and Required Vote at Stockholder Meetings.

(a) Except as otherwise required by applicable law, the Restated Certificate or these Restated Bylaws, at all meetings of Stockholders the presence, in person or represented by proxy, of the holders of outstanding shares representing at least a majority of the total voting power entitled to vote at a meeting of Stockholders shall constitute a quorum for the transaction of business; provided, however, that where a separate vote of a class or classes or series of stock is required, the presence in person or represented by proxy of the holders of outstanding shares representing at least a majority of the total voting power of all outstanding shares of such class or classes or series shall constitute a quorum thereof entitled to take action with respect to such separate vote.

(b) Except as otherwise required by applicable law, the Restated Certificate or these Restated Bylaws, each holder of stock of the Corporation entitled to vote on any matter at any meeting of the Stockholders shall be entitled to one vote for each share of such stock standing in the name of such holder on the stock ledger of the Corporation on the record date for the determination of the Stockholders entitled to vote at the meeting. Except as otherwise required by applicable law, the Restated Certificate or these Restated Bylaws, including, without limitation, Section 3.3 hereof, the affirmative vote of a majority in voting power of the shares

present in person or represented by proxy and entitled to vote on the subject matter at a meeting of Stockholders at which a quorum is present shall be the act of the Stockholders. Except as required by applicable law, the method of voting and the manner in which votes are counted shall be discretionary with the presiding officer at the meeting.

(c) The holders of a majority in voting power of the shares entitled to vote and present in person or represented by proxy at any meeting of Stockholders, whether or not a quorum is present, may adjourn such meeting to another time and place. At any such adjourned meeting at which a quorum shall be present, any business may be transacted that might have been transacted at the meeting as originally called. Unless otherwise required by applicable law, the Restated Certificate or these Restated Bylaws, no notice of an adjourned meeting need be given.

2.7 Proxies. Each Stockholder entitled to vote at a meeting of Stockholders may authorize another person or persons to act for him or her by proxy executed in writing by the Stockholder or as otherwise permitted by law, or by his or her duly authorized attorney-in-fact, but such proxy shall no longer be valid eleven months after the date of such proxy. Such proxy must be filed with the Secretary of the Corporation or his or her representative at or before the time of the meeting.

2.8 Inspectors. The Board by resolution shall appoint one or more inspectors, which inspector or inspectors may include individuals who serve the Corporation in other capacities, including, without limitation, as officers, employees, agents or representatives of the Corporation, to act at the meeting and make a written report thereof. One or more persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate has been appointed to act, or if all inspectors or alternates who have been appointed are unable to act, at the meeting of Stockholders, the chairman of the meeting shall appoint one or more inspectors to act at the meeting.

ARTICLE 6

Stock And Transfers Of Stock

6.1 Stock Certificates. The Common Stock shall be uncertificated. The shares of the Corporation other than the Common Stock shall be represented by certificates or shall be uncertificated. The Board shall have the power and authority to make such rules and regulations as it may deem expedient concerning the issue, transfer and registration of uncertificated shares or certificates for shares of stock of the Corporation. Each certificate shall be signed by the Chairman or the President or a Vice Chairman or a Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, certifying the number of certificated shares owned by such Stockholder in the Corporation. Any or all of the signatures on the certificate may be a facsimile. In case any officer, Transfer Agent or Registrar who has signed or whose facsimile signature has been placed upon a certificate shall cease to be such officer, Transfer Agent or Registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he or she were such officer, Transfer Agent or Registrar at the date of issuance.

6.2 Transfer Agents and Registrars. The Board may, in its discretion, appoint responsible banks or trust companies as the Board may deem advisable, from time to time, to act as Transfer Agents and Registrars of the stock of the Corporation; and, when such appointments shall have been made, no stock certificate shall be valid until countersigned by one of such Transfer Agents and registered by one of such Registrars.

6.3 Transfers of Stock. Transfers of shares of stock of the Corporation shall be made on the stock ledger of the Corporation only upon authorization by the record holder thereof or by such holder’s attorney, successor or assignee thereunto authorized by power of attorney (or other proper evidence of succession, assignment or authority to transfer) duly executed and filed with the Corporation’s Transfer Agent or Registrar. Except as otherwise provided in the Restated Certificate, and subject to any other transfer restriction applicable thereto, shares of certificated stock may be transferred by delivery of the certificates therefor, accompanied either by an assignment in writing on the back of the certificates or by written power of attorney to sell, assign and transfer the same with reasonable assurances given that such endorsement is genuine and that all applicable taxes thereon have been paid, signed by the record holder thereof; but no transfer shall affect the right of the Corporation to pay any dividend upon the stock to the holder

of record thereof, or to treat the holder of record as the holder in fact thereof for all purposes, and no transfer shall be valid, except between the parties thereto, until such transfer shall have been made upon the books of the Corporation. No transfer of stock in violation of the provisions of Article Fourth, Part III, Section 1 or Article Fourth, Part IV, Section 1 of the Restated Certificate shall be valid as against the Corporation for any purpose.

6.4 Lost Certificates. In case any certificate of stock shall be lost, stolen or destroyed, the Board, in its discretion, may authorize the issuance of a substitute certificate in place of the certificate lost, stolen or destroyed and may cause such substitute certificate to be countersigned by the appropriate Transfer Agent (if any) and registered by the appropriate Registrar (if any), provided that, in each such case, the applicant for a substitute certificate shall furnish to the Corporation and to such of its Transfer Agents and Registrars as may require the same, evidence to their satisfaction, in their discretion, of the loss, theft or destruction of such certificate and of the ownership thereof, and also such security or indemnity as may be required by them.

6.5 Record Date.

(a) In order that the Corporation may determine the Stockholders entitled to notice of or to vote at any meeting of Stockholders or any adjournment thereof, or, subject to applicable law, to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board is authorized, from time to time, to fix, in advance, a record date, which shall not be more than sixty (60) nor less than ten (10) days before the date of such Stockholder meeting, nor more than sixty (60) days prior to any other action.

(b) A determination of Stockholders of record entitled to notice of or to vote at a meeting of Stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for the adjourned meeting.

(c) Only Stockholders that are Stockholders of record on the date so fixed shall be entitled to notice of, and to vote at, a meeting of Stockholders and any adjournment thereof or to receive payment of any dividend or other distribution or allotment of any rights or to exercise any rights in respect of any change, conversion or exchange of stock or for any other purpose, as applicable, notwithstanding any transfer of any stock on the stock ledger of the Corporation after any record date so fixed.

The Board of Directors from time to time may confer like powers upon any other person or persons.

7.6 Dividends. Dividends upon the capital stock may be declared by the Board at any regular or special meeting and may be paid in cash or in property or in shares of the capital stock. Before paying any dividend or making any distribution of profits, the Directors may set apart out of any funds of the Corporation available for dividends a reserve or reserves for any proper purpose and may later or abolish any such reserve or reserves.

7.7 Corporate Seal. The seal of the Corporation shall be circular in form and shall bear, in addition to any other emblem or device approved by the Board, the name of the Corporation and the words “Corporate Seal” and “Delaware.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or in any other manner reproduced.

Article 1. Quantity, Model, Description and Inspection.

The aircraft to be delivered to Customer will be designated as Model 787 aircraft (the Aircraft).

Twelve (12) months prior to delivery of Customer’s first Aircraft, Boeing will provide Customer a Boeing document defining a customer inspection process appropriate to the 787 manufacturing process (787 Inspection Process) which will apply in lieu of inspection processes traditionally applicable to other models of aircraft and will supersede the provisions of Article 5.2 of the AGTA.

Article 2. Delivery Schedule.

Additional advance payments for each Aircraft are due as specified in and on the first business day of the months listed in the attached Table 1.

4.3 For any Aircraft whose scheduled month of delivery is less than 24 months from the date of this Purchase Agreement, the total amount of advance payments due for payment upon signing of this Purchase Agreement will include all advance payments which are past due in accordance with the standard advance payment schedule set forth in paragraph 4.2 above.

4.4 Customer will pay the balance of the Aircraft Price of each Aircraft at delivery. The Aircraft Price for each Aircraft will be re-calculated at the time that Aircraft is delivered using the then available escalation factors for the month when that Aircraft is delivered to calculate the Escalation Adjustment as defined in Supplemental Exhibit AE1.

Article 5. Additional Terms.

5.1 Excusable Delay. Article 7.1 of the basic articles of the AGTA in so far as it applies to the Aircraft only is revised to read as follows:

A delay resulting from any such cause is defined as an Excusable Delay.

5.2 Aircraft Information Table. Table 1 consolidates information contained in Articles 1, 2, 3 and 4 with respect to (i) quantity of Aircraft, (ii) applicable Detail Specification for the Aircraft, (iii) month and year of scheduled deliveries of the Aircraft, (iv) Aircraft Basic Price, (v) escalation factors applicable to the Aircraft and (vi) Advance Payment Base Prices and advance payments applicable to the Aircraft and their schedules.

5.5 Customer Support Variables.

Special Items

NOTE 10—SPECIAL ITEMS

Special Charges. For the three and six months ended June 30, special charges consisted of the following (in millions):

	Three Months Ended June 30,					Six Months Ended June 30,
	2013		2012			2013			2012
Merger integration-related costs	$	45	$	137		$	115		$	271
Additional costs associated with the temporarily grounded Boeing 787 aircraft		7		—			18			—
Voluntary severance and benefits		—		76			14			125
Gains on sale of assets and other special items, net		—		(7	)		(3	)		(26	)
Subtotal special charges		52		206			144			370
Income tax benefit		—		—			—			(2	)
Total special charges, net of income taxes	$	52	$	206		$	144		$	368

Merger integration-related costs include compensation costs related to systems integration and training, costs to repaint aircraft and other branding activities, new uniforms, costs to write-off or accelerate depreciation on systems and facilities that are no longer used or planned to be used for significantly shorter periods, relocation costs for employees and severance primarily associated with administrative headcount reductions.

During the six months ended June 30, 2013, the Company recorded $14 million associated with a voluntary program offered by United in which flight attendants took an unpaid 13-month leave of absence. The flight attendants continue to receive medical benefits and other company benefits while on leave under this program. Approximately 1,300 flight attendants opted to participate in the program. In addition, the Company recorded $18 million associated with the temporary grounding of its Boeing 787 aircraft, $7 million of which was recorded during the second quarter of 2013. The charges are comprised of aircraft depreciation expense and dedicated personnel costs that the Company incurred while the aircraft were grounded. The aircraft returned to service in May of 2013. Also, the Company recorded a $5 million gain related to a contract termination and $2 million in losses on the sale of assets.

During the three and six months ended June 30, 2012, the Company recorded $76 million and $125 million of severance and benefits associated with three voluntary employee programs, respectively. During the first quarter of 2012, approximately 400 mechanics offered to retire early in exchange for a cash severance payment that was based on the number of years of service each employee had accumulated. The Company also offered a voluntary leave of absence program that approximately 1,800 flight attendants accepted, which allows for continued medical coverage during the leave of absence period. During the second quarter of 2012, as part of the recently amended collective bargaining agreement with the Association of Flight Attendants, the Company offered a voluntary program for flight attendants at United to retire early in exchange for a cash severance payment. The payments are dependent on the number of years of service each employee has accumulated. Approximately 1,300 flight attendants accepted this program and the Company estimates the amount for this voluntary program to be approximately $76 million.

In March 2013, the Company agreed to sell up to 30 Boeing 757-200 aircraft to FedEx Corporation beginning in April 2013. As of December 31, 2012, the Company operated 133 such aircraft. Given the planned sale of up to 30 of these aircraft, the Company evaluated the entire fleet and determined that no impairment existed. However, the Company adjusted the salvage value of the aircraft designated for sale to its sales price and will record additional depreciation from the agreement date to the date of sale. This additional depreciation is not classified as special. The additional depreciation in the first six months of 2013 totaled $40 million and is estimated to be approximately $80 million for the full year 2013.

Accruals

The accrual for severance and medical costs was $38 million as of June 30, 2013, compared to $153 million as of June 30, 2012. In addition, the accrual balance of future lease payments on permanently grounded aircraft was $3 million as of June 30, 2013, compared to $8 million as of June 30, 2012.

The severance-related accrual as of June 30, 2013 is expected to be paid through 2015. Lease payments for grounded aircraft are expected to continue through 2013.

Frequent Flyer Accounting

NOTE 1—FREQUENT FLYER ACCOUNTING

Frequent Flyer Awards. The Company revised the estimated selling price of miles as a prospective change in estimate, effective January 1, 2012, based on the price at which the Company sells miles to Star Alliance partners in its reciprocal frequent flyer agreements as the best estimate of the selling price for these miles. Any changes to the composition of Star Alliance airline partners could result in a change to the amount and method we use to determine the estimated selling price. On February 14, 2013, US Airways Group, Inc. announced an agreement to merge with AMR Corporation and its intent to exit Star Alliance as a result of such merger. We are currently evaluating the potential impact of any changes to the estimated selling price of miles as a result of this merger.

Income Taxes

Income Taxes

NOTE 4—INCOME TAXES

Our effective tax rates are lower than the federal statutory rate of 35% primarily because of the impact of changes to existing valuation allowances. We continue to provide a valuation allowance for our deferred tax assets in excess of deferred tax liabilities because we have concluded that it is more likely than not that such deferred tax assets will ultimately not be realized.

United files a consolidated federal income tax return with UAL. Under an intercompany tax allocation policy, United computes, records and pays UAL for its own tax liability as if United were a separate company filing a separate return. In determining its own tax liabilities, United takes into account all tax credits or benefits generated and utilized as a separate company and it is compensated for the aforementioned tax benefits only if it would be able to use those benefits on a separate company basis.

NOTE 2—NEW ACCOUNTING PRONOUNCEMENTS

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02 (“ASU 2013-02”), Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Some of the key amendments require the Company to present, either on the face of the statement of operations or in the notes, the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, the Company is required to cross-reference to other disclosures that provide additional detail about those amounts. ASU 2013-02 became effective for the Company’s annual and interim periods beginning January 1, 2013, and the required disclosures are included in Note 11 of this report.

Hedging Activities

NOTE 7—HEDGING ACTIVITIES

Aircraft Fuel Hedges. To protect against increases in the prices of aircraft fuel, the Company routinely hedges a portion of its future fuel requirements. As of June 30, 2013, the Company had hedged approximately 47% and 18% of its projected fuel requirements (942 million and 706 million gallons, respectively) for the remainder of 2013 and 2014, respectively, with commonly used financial hedge instruments based on aircraft fuel or closely related commodities, such as heating oil, diesel fuel and crude oil. As of June 30, 2013, the Company had fuel hedges expiring through December 2014. The Company does not enter into derivative instruments for non-risk management purposes.

Upon proper qualification, the Company accounts for certain fuel derivative instruments as cash flow hedges. All derivatives designated as hedges that meet certain requirements are granted hedge accounting treatment. The types of instruments the Company utilizes that qualify for special hedge accounting treatment typically include swaps, call options, collars (which consist of a purchased call option and a sold put option) and four-way collars (a collar with a higher strike sold call option and a lower strike purchased put option). Generally, utilizing hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the underlying fuel is consumed and recorded in fuel expense. The Company is exposed to the risk that its hedges may not be effective in offsetting changes in the cost of fuel and that its hedges may not continue to qualify for hedge accounting. Hedge ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume fuel. To the extent that the periodic changes in the fair value of the derivatives are not effective, that ineffectiveness is classified as Nonoperating income (expense): Miscellaneous, net in the statements of consolidated operations.

The Company also utilizes certain derivative instruments that are economic hedges but do not qualify for hedge accounting under U.S. GAAP. As with derivatives that qualify for hedge accounting, the purpose of these economic hedges is to mitigate the adverse financial impact of potential increases in the price of fuel. Currently, the only such economic hedges in the Company’s hedging portfolio are three-way collars (which consist of a collar with a cap on maximum price protection available). The Company records changes in the fair value of three-way collars to Nonoperating income (expense): Miscellaneous, net in the statements of consolidated operations.

If the Company terminates a derivative prior to its contractual settlement date, then the cumulative gain or loss recognized in AOCI at the termination date remains in AOCI until the forecasted transaction occurs. In a situation where it becomes probable that a hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. All cash flows associated with purchasing and settling derivatives are classified as operating cash flows in the condensed statements of consolidated cash flows.

The Company records each derivative instrument as a derivative asset or liability (on a gross basis) in its consolidated balance sheets, and, accordingly, records any related collateral on a gross basis.

The following tables present information about the financial statement classification of the Company’s derivatives (in millions):

Derivative Credit Risk and Fair Value

The Company is exposed to credit losses in the event of nonperformance by counterparties to its derivative instruments. While the Company records derivative instruments on a gross basis, the Company monitors its net derivative position with each counterparty to monitor credit risk. Based on the fair value of our fuel derivative instruments, our counterparties may require us to post collateral when the price of the underlying commodity decreases, and we may require our counterparties to provide us with collateral when the price of the underlying commodity increases. The following table presents information related to the Company’s derivative credit risk as of June 30, 2013 (in millions):

Net derivative liability with counterparties	$	23

As of June 30, 2013, the Company’s auction rate securities, which had a par value of $125 million, were variable-rate debt instruments with interest rates that reset every 7, 28 or 35 days, depending on the terms of the particular instrument. These securities are backed by pools of student loans guaranteed by state-designated guaranty agencies and reinsured by the U.S. government. All of the auction rate securities that the Company holds are senior obligations under the applicable indentures authorizing the issuance of the securities.

As of June 30, 2013, United’s EETC securities, which were repurchased in open market transactions in 2007, have unrealized gains of $3 million. All changes in the fair value of these investments have been classified within accumulated other comprehensive income.

United’s debt-related derivatives presented in the tables above relate to (a) supplemental indenture agreements that provide that United’s convertible debt is convertible into shares of UAL common stock upon the terms and conditions specified in the indentures, and (b) the embedded conversion options in United’s convertible debt that are required to be separated and accounted for as though they are free-standing derivatives as a result of the United debt becoming convertible into the common stock of a different reporting entity. The derivatives described above relate to the 6% convertible junior subordinated debentures due 2030 and the 4.5% convertible notes due 2015. These derivatives are reported in United’s separate financial statements and eliminated in consolidation for UAL.

Derivative instruments and investments presented in the tables above have the same fair value as their carrying value. The table below presents the carrying values and estimated fair values of financial instruments not presented in the tables above (in millions):

(a) Broker quotes obtained by a third-party valuation service.

(b) Represents the credit risk premium of the EETC structure above the risk-free rate that the Company has determined market participants would use in pricing the instruments.

(c) Represents the range in volatility estimates that the Company has determined market participants would use when pricing the instruments.

(d) Represents the range of Company-specific risk adjustments that the Company has determined market participants would use as a model input.

Valuation Processes—Level 3 Measurements—Depending on the instrument, the Company utilizes broker quotes obtained from third-party valuation services, discounted cash flow methods, or option pricing methods, as indicated above. Valuations using discounted cash flow methods are generally conducted by the Company. Valuations using option pricing models are generally provided to the Company by third-party valuation experts. Each reporting period, the Company reviews the unobservable inputs used by third-party valuation experts for reasonableness utilizing relevant information available to the Company from other sources.

As of June 30, 2013, the Company began using broker quotes obtained from a valuation service (in replacement of a discounted cash flows method) for valuing auction rate securities. This approach provides the best available information.

Sensitivity Analysis—Level 3 Measurements—Changes in the structure credit risk would be unlikely to cause material changes in the fair value of the EETCs.

The significant unobservable inputs used in the fair value measurement of the United convertible debt derivative assets and liabilities are the expected volatility in UAL common stock and the Company’s own credit risk. Significant increases (decreases) in expected stock volatility would result in a higher (lower) fair value measurement. Significant increases (decreases) in the Company’s own credit risk would result in a lower (higher) fair value measurement. A change in one of the inputs would not necessarily result in a directionally similar change in the other.

Fair value of the financial instruments included in the tables above was determined as follows:

Description	Fair Value Methodology
Cash and cash equivalents	The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term investments and Restricted cash	Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, (c) internally-developed models of the expected future cash flows related to the securities, or (d) broker quotes obtained by third-party valuation services.
Fuel derivatives	Derivative contracts are privately negotiated contracts and are not exchange traded. Fair value measurements are estimated with option pricing models that employ observable inputs. Inputs to the valuation models include contractual terms, market prices, yield curves, fuel price curves and measures of volatility, among others.
Foreign currency derivatives	Fair value is determined with a formula utilizing observable inputs. Significant inputs to the valuation models include contractual terms, risk-free interest rates and forward exchange rates.
Debt	Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities.
Convertible debt derivative asset and option liability	United used a binomial lattice model to value the conversion options and the supplemental derivative assets. Significant binomial model inputs that are not objectively determinable include volatility and discount rate.

Debt

NOTE 9—DEBT

As of June 30, 2013, a substantial portion of our assets are pledged as collateral for our debt. These assets principally consist of aircraft, route authorities and loyalty program intangible assets. As of June 30, 2013, the Company was in compliance with its debt covenants.

Unsecured 6.375% Senior Notes. In May 2013, UAL issued $300 million aggregate principal amount of 6.375% Senior Notes due June 1, 2018. The notes are fully and unconditionally guaranteed and recorded by United on its balance sheet as debt.

6% Convertible Senior Notes. During the second quarter of 2013, UAL issued approximately 22 million shares of UAL common stock pursuant to agreements that UAL entered into with certain of its securityholders in exchange for approximately $189 million in aggregate principal amount of UAL’s outstanding 6% convertible senior notes due 2029 held by such securityholders. See Note 3 of this report for more information.

2013 Credit and Guaranty Agreement. On March 27, 2013, United and UAL entered into the Credit Agreement as the borrower and guarantor, respectively. The Credit Agreement consists of a $900 million term loan due April 1, 2019 and a $1.0 billion revolving credit facility available for drawing until April 1, 2018. As of June 30, 2013, United had its entire capacity of $1.0 billion available under the revolving credit facility. The obligations of United under the Credit Agreement are secured by liens on certain international route authorities between certain specified cities, certain take-off and landing rights and related assets of United.

Borrowings under the Credit Agreement bear interest at a variable rate equal to LIBOR, subject to a 1% floor, plus a margin of 3.0% per annum, or another rate based on certain market interest rates, plus a margin of 2.0% per annum. The principal amount of the term loan must be repaid in consecutive quarterly installments of 0.25% of the original principal amount thereof, commencing on June 30, 2013, with any unpaid balance due on April 1, 2019. United may prepay all or a portion of the loan from time to time, at par plus accrued and unpaid interest. United pays a commitment fee equal to 0.75% per annum on the undrawn amount available under the revolving credit facility.

The Credit Agreement includes covenants that, among other things, require the Company to maintain at least $3.0 billion of unrestricted liquidity and a minimum ratio of appraised value of collateral to the outstanding obligations under the Credit Agreement of 1.67 to 1.0, and restrict the Company’s ability to incur additional indebtedness, issue preferred stock, make investments or pay dividends. The Credit Agreement contains events of default customary for this type of financing, including a cross default and cross acceleration provision to certain other material indebtedness of the Company. Under the provisions of the Credit Agreement, UAL’s ability to pay dividends on or repurchase UAL’s common stock is restricted.

United Amended Credit Facility. On March 27, 2013, the Company used $900 million from the Credit Agreement, together with approximately $300 million of cash to retire the entire principal balance of a $1.2 billion term loan due 2014 that was outstanding under United’s Amended and Restated Revolving Credit, Term Loan and Guaranty Agreement, dated as of February 2, 2007 (the “Amended Credit Facility”). The Amended Credit Facility was terminated concurrently with the repayment of the term loan.

$500 Million Revolving Credit Facility. On March 27, 2013, the Company terminated the $500 million revolving credit facility that it had previously entered into in December 2011. There were no outstanding borrowings under the revolving credit facility.

Debt Redemptions. On February 1, 2013, United redeemed all of the $400 million aggregate principal amount of its 9.875% Senior Secured Notes due 2013 and $200 million aggregate principal amount of 12.0% Senior Second Lien Notes due 2013. On February 8, 2013, United redeemed all $123 million aggregate principal amount of the B tranche of the 2006-1 EETC equipment notes due 2013. On April 1, 2013, United redeemed all of the $180 million aggregate principal amount of the senior tranche of the 2006-1 EETC equipment notes due 2013.

EETCs. In October 2012, United created two pass-through trusts, one of which issued $712 million aggregate principal amount of Class A pass-through certificates with a stated interest rate of 4% and the second of which issued $132 million aggregate principal amount of Class B pass-through certificates with a stated interest rate of 5.5%. The proceeds of the issuance of the Class A and Class B pass-through certificates, which amounted to $844 million, are used to purchase equipment notes issued by United. Of the $844 million in proceeds raised by the pass-through trusts, United received $696 million as of June 30, 2013, of which $202 million and $403 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trusts. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates. The proceeds have been and are expected to fund the acquisition of new aircraft.

In December 2012, United created one pass-through trust which issued $425 million aggregate principal amount of Class C pass-through certificates with a stated interest rate of 6.125%. The proceeds of the issuance of the Class C pass-through certificates are used to purchase equipment notes issued by United related to the aircraft financed in both the March and October 2012 EETC financings. Of the $425 million in proceeds raised by the pass-through trust, United received $385 million as of June 30, 2013, of which $53 million and $107 million was received in the three and six months ended June 30, 2013, respectively. United expects to receive the remaining proceeds from the issuance through the second half of 2013 as aircraft are delivered and United issues equipment notes to the trust. The Company records the debt obligation upon issuance of the equipment notes rather than upon the initial issuance of the pass-through certificates.

During the three and six months ended June 30, 2013, the Company contributed $38 million and $79 million, respectively, to its tax-qualified defined benefit pension plans.

Curtailments, Settlements and Plan Remeasurements. During June 2013, the Company announced it would freeze benefits for management and administrative employees under one of its defined benefit pension plans, effective December 31, 2013. As a result, the Company recognized a $2 million curtailment loss in earnings in the second quarter. The Company also recognized a settlement gain of $1 million in earnings resulting from certain lump-sum payments under a separate defined benefit pension plan. Application of curtailment and settlement accounting required the Company to remeasure the assets and liabilities of the two plans in the second quarter. The Company remeasured the pension plans’ liabilities using an average weighted discount rate of 4.74% compared to the year-end 2012 discount rate of 4.24%. As a result of the remeasurements, curtailment and settlement, the projected benefit obligation of the plans decreased by $434 million and Other comprehensive loss decreased by an actuarial gain of $442 million, of which approximately $84 million resulted from the curtailment. These items will also result in a decrease of approximately $30 million in the expected net periodic benefit cost for the remainder of 2013. The Company recognizes the earnings impacts of its pension plans in Salaries and related costs in the statements of consolidated operations.

Share-Based Compensation. In February 2013, UAL granted share-based compensation awards pursuant to the United Continental Holdings, Inc. 2008 Incentive Compensation Plan. These share-based compensation awards include approximately 0.5 million shares of restricted stock and 0.5 million restricted stock units (“RSUs”) that vest pro-rata over three years on the anniversary of the grant date. The time-vested RSUs are cash-settled based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. In addition, the Company granted 1.3 million performance-based RSUs that will vest based on the Company’s return on invested capital for the three years ending December 31, 2015. If this performance condition is achieved, cash payments will be made after the end of the performance period based on the 20-day average closing price of UAL common stock immediately prior to the vesting date. The Company accounts for the RSUs as liability awards. The table below presents information related to share-based compensation (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,

(a) Includes $3 million and $11 million of expense recognized in merger integration-related costs for the three and six months ended June 30, 2013, respectively. Includes $3 million and $7 million of expense recognized in merger integration-related costs for the three and six months ended June 30, 2012, respectively.

Profit Sharing Plans. In 2013 and 2012, a majority of all employees participate in profit sharing plans, which pay 15% of total pre-tax earnings, excluding special items and share-based compensation expense, to eligible employees when pre-tax profit, excluding special items, profit sharing expense and share-based compensation program expense, exceeds $10 million. Eligible U.S. co-workers in each participating work group receive a profit sharing payout using a formula based on the ratio of each qualified co-worker’s annual eligible earnings to the eligible earnings of all qualified co-workers in all domestic workgroups. The international profit sharing plan pays eligible non-U.S. co-workers the same percentage of eligible pay that is calculated under the U.S. profit sharing plan. Profit sharing expense is recorded as a component of salaries and related costs in the consolidated statements of operations. Our profit sharing plan will change in 2014. Beginning with 2014, pilots’ share of profit sharing payments will be limited to an amount that is their pro-rata share of 10% of the Company’s profit up to a pre-tax margin of 6.9% and 20% of the Company’s profit in excess of a pre-tax margin of 6.9%. The profit sharing plan for the other workgroups is unchanged.

Commitments and Contingencies

NOTE 8—COMMITMENTS AND CONTINGENCIES

Commitments. On April 29, 2013, United entered into an agreement to purchase 30 Embraer EMB175 regional jets, scheduled for delivery in 2014 and 2015.

On June 17, 2013, United entered into supplemental agreements to United’s 787 aircraft purchase agreements with The Boeing Company (“Boeing”) to add to its existing firm order of Boeing 787 widebody aircraft ten Boeing 787-10 aircraft, convert an existing firm order for ten Boeing 787 aircraft into Boeing 787-10 aircraft and make certain other changes to those agreements. On June 19, 2013, United entered into amendments to its A350 purchase agreement with Airbus S.A.S. (“Airbus”) to add to its existing firm order of Airbus A350 widebody aircraft ten Airbus A350-1000 aircraft, convert its existing firm order for 25 Airbus A350-900 aircraft into Airbus A350-1000 aircraft and make certain other changes to the agreement. The Company expects to take delivery of the Boeing 787-10 aircraft and Airbus A350-1000 aircraft between 2018 and 2024.

As of June 30, 2013, UAL and United had the following commitments to purchase aircraft:

UAL Aircraft Commitments. UAL had firm commitments to purchase 100 new Boeing 737 MAX 9 aircraft scheduled for delivery from 2018 through 2025. UAL also had options to purchase additional Boeing 737 MAX 9 aircraft. UAL intends in the future to assign its interest under the purchase agreement for the 737 MAX 9 aircraft to United.

United Aircraft Commitments. United had firm commitments to purchase 199 new aircraft (59 Boeing 787 aircraft, 75 Boeing 737 aircraft, 35 Airbus A350-1000 aircraft, and 30 Embraer EMB175 aircraft) scheduled for delivery from July 1, 2013 through 2025. United also had options and purchase rights for additional aircraft. In the second quarter of 2013, United took delivery of six Boeing 737-900ER. In the remainder of 2013, United expects to take delivery of twelve Boeing 737-900ER aircraft and two Boeing 787-8 aircraft.

United had arranged for EETC financing of 14 Boeing 737-900ER aircraft, six of which were delivered during the second quarter of 2013 and two of which are scheduled to be delivered during the remainder of 2013. United also has arranged for EETC financing of one Boeing 787-8 aircraft and a bank debt financing commitment for one Boeing 737-900ER aircraft scheduled for delivery in the second half of 2013. In addition, United had secured backstop financing commitments from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. However, the Company does not have backstop financing or any financing currently in place for its other firm aircraft orders. Financing will be necessary to satisfy the Company’s capital commitments for its firm order aircraft and other related capital expenditures. The Company can provide no assurance that any financing not already in place for aircraft and spare engine deliveries will be available to the Company on acceptable terms when necessary or at all. See Note 9 of this report for additional information on aircraft financing.

The Company has concluded its discussions with Boeing regarding certain contractual matters, including expected fuel burn, for current and future deliveries of certain Boeing 787 aircraft, and has reached a resolution with Boeing regarding compensation to be received in connection with those matters.

The table below summarizes the capital commitments of UAL and United (including those intended to be assigned from UAL) as of June 30, 2013, which primarily relate to the acquisition of aircraft and related spare engines, aircraft improvements and acquisition of information technology services and assets:

(In billions)
Last six months of 2013	$	1.2
2014		2.5
2015		2.0
2016		2.4
2017		1.4
After 2017		14.0
	$	23.5

Any incremental firm aircraft orders, including through the exercise of purchase options, will increase the total future capital commitments of the Company.

Aircraft Operating Leases and Capacity Purchase Agreements

In May 2013, United entered into a capacity purchase agreement with SkyWest Airlines, Inc. (“SkyWest”), a wholly-owned subsidiary of SkyWest, Inc., to operate 40 Embraer EMB175 aircraft under the United Express brand. SkyWest will purchase these 76-seat aircraft with deliveries in 2014 and 2015. These 40 aircraft are in addition to United’s April 2013 agreement to purchase 30 Embraer EMB175 aircraft, which will be operated by a different United Express carrier.

The table below summarizes the Company’s future payments through the end of the terms of our capacity purchase commitments, excluding variable pass-through costs such as fuel and landing fees, among others. In addition, the table below summarizes the Company’s scheduled future minimum lease payments under aircraft operating leases having initial or remaining noncancelable lease terms of more than one year and includes aircraft rent under capacity purchase agreements, including estimated commitments from the Embraer EMB175 aircraft which will be delivered starting in 2014.

Facility and Other Operating Leases

In April 2013, United signed a 20-year lease extension with the Port Authority of New York and New Jersey to continue its use of Terminal C1 and C2 at Newark Liberty International Airport (“Newark”). United also committed to invest an additional $150 million in facility upgrades at Newark to enhance the customer experience and efficiency of the operation. The table below summarizes the Company’s scheduled future minimum lease payments under facility operating leases having initial or remaining noncancelable lease terms of more than one year.

2015		900
2016		829
2017		782
After 2017		6,814
	$	10,957

Guarantees and Off-Balance Sheet Financing

Guarantees. United is the guarantor of approximately $1.9 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with $1.7 billion of these obligations are accounted for as operating leases with the associated expense recorded on a straight-line basis resulting in ratable accrual of the lease obligation over the expected lease term. The leasing arrangements associated with $180 million of these obligations are accounted for as capital leases. All these bonds are due between 2015 and 2038.

In the Company’s financing transactions that include loans, the Company typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans in which the interest rate is based on the London Interbank Offered Rate (“LIBOR”), for certain other increased costs that the lenders incur in carrying these loans as a result of any change in law, subject in most cases to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At June 30, 2013, the Company had $2.0 billion of floating rate debt and $317 million of fixed rate debt, with remaining terms of up to nine years, that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to eight years and an aggregate balance of $2.2 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.

Credit Facilities. On March 27, 2013, United and UAL entered into a new Credit and Guaranty Agreement (the “Credit Agreement”) as the borrower and guarantor, respectively, that provides United with a $1.0 billion revolving credit facility. As of June 30, 2013, United had its entire capacity of $1.0 billion available under the revolving credit facility. See Note 9 of this report for more information.

Labor Negotiations. As of June 30, 2013, United had approximately 88,000 active employees, of whom approximately 80% were represented by various labor organizations. Having reached a ratified joint collective bargaining agreement with our pilots represented by the Air Line Pilots Association, International, we are currently in the process of negotiating joint collective bargaining agreements with our other major work groups, including our public contact co-workers, technicians, flight attendants and dispatchers.
