Results of Review of Interim Financial Statements

We have reviewed the accompanying consolidated balance sheet of Delta Air Lines, Inc. (the Company) as of September 30, 2023, the related condensed consolidated statements of operations and comprehensive income and consolidated statements of stockholders' equity for the three-month and nine-month periods ended September 30, 2023 and 2022, condensed consolidated statements of cash flows for the nine-month periods ended September 30, 2023 and 2022, and the related notes (collectively referred to as the "condensed consolidated interim financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed consolidated interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2022, the related consolidated statements of operations, comprehensive income/(loss), cash flows, and stockholders' equity for the year then ended, and the related notes (not presented herein); and in our report dated February 10, 2023, we expressed an unqualified audit opinion on those Consolidated Financial Statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2022, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our consolidated subsidiaries, and have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K for the year ended December 31, 2022.

Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair statement of results for the interim periods presented.

Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices and other factors, operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of operating results for the entire year.

We reclassified certain prior period amounts to conform to the current period presentation. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes.

Passenger revenue$13,119 $11,464 $36,735 $29,329 

Ticket

We recognized approximately $6.7 billion and $3.9 billion in passenger revenue during the nine months ended September 30, 2023 and 2022, respectively, that had been recorded in our air traffic liability balance at the beginning of those periods.

As of September 30, 2023, all of our air traffic liability was recorded as a current liability. As of December 31, 2022, our air traffic liability was $8.3 billion, of which $100 million was included in other noncurrent liabilities on our Consolidated Balance Sheet ("balance sheet").

Loyalty Travel Awards

Our SkyMiles loyalty program allows customers to earn mileage credits ("miles") by flying on Delta, Delta Connection and other airlines that participate in the loyalty program. Loyalty travel awards revenue is related to the redemption of miles for air travel. Customers can also earn miles through participating companies, such as credit card companies, hotels, car rental agencies and ridesharing companies, who purchase miles from us. Our most significant contract to sell miles relates to our co-brand credit card relationship with American Express. During the nine months ended September 30, 2023 and 2022, total cash sales from marketing agreements related to our loyalty program were $5.2 billion and $4.1 billion, respectively, which are allocated to travel and other performance obligations.

Delta Air Lines, Inc. | September 2023 Form 10-Q                                 7

Notes to the Condensed Consolidated Financial Statements
Current Activity of the Loyalty Program. Miles are combined in one homogeneous pool and are not separately identifiable. Therefore, revenue is comprised of miles that were part of the loyalty program deferred revenue balance at the beginning of the period as well as miles that were issued during the period. The timing of mile redemptions can vary widely; however, the majority of miles have historically been redeemed within two years of being earned.

The table below presents the activity of the current and noncurrent loyalty program deferred revenue and includes miles earned through travel and miles sold to participating companies, which are primarily through marketing agreements.

Revenue by Geographic Region

Operating revenue for the airline segment is recognized in a specific geographic region based on the origin, flight path and destination of each flight segment. A significant portion of the refinery segment's revenues typically consists of fuel sales to support the airline, which is eliminated in the Condensed Consolidated Financial Statements. The remaining operating revenue for the refinery segment is included in the domestic region. Our passenger and operating revenue by geographic region is summarized in the following tables:

Cash Equivalents and Restricted Cash Equivalents. Cash equivalents generally consist of money market funds. Restricted cash equivalents generally consist of money market funds, time deposits, commercial paper and negotiable certificates of deposit, which primarily relate to certain self-insurance obligations and airport commitments. Restricted cash equivalents are recorded in prepaid expenses and other on our balance sheet. The fair value of these cash equivalents is based on a market approach using prices generated by market transactions involving identical or comparable assets.

Short-Term Investments. The fair values of our short-term investments are based on a market approach using industry standard valuation techniques that incorporate observable inputs such as quoted market prices, interest rates, benchmark curves, credit ratings of the security and other observable information.

As of September 30, 2023, the estimated fair value of our short-term investments was $2.2 billion. Of these investments, $2.1 billion are expected to mature in one year or less, with the remainder maturing by the first quarter of 2026. Investments with maturities beyond one year when purchased are classified as short-term investments if they are expected to be available to support our short-term liquidity needs.

Long-Term Investments and Related. Our long-term investments measured at fair value primarily consist of equity investments, which are valued based on market prices or other observable transactions and inputs, and are recorded in equity investments on our balance sheet. Our equity investments in private companies are classified as Level 3 in the fair value hierarchy as their equity is not traded on a public exchange and our valuations incorporate certain unobservable inputs, including non-public equity issuances. As of September 30, 2023 our equity investment in Wheels Up Experience Inc. ("Wheels Up") is classified as Level 3 in the fair value hierarchy. In prior periods, this investment was classified as Level 1. We determined the quoted price of its publicly-traded shares does not represent fair value after the closing of Wheels Up's $500 million credit facility on September 20, 2023. In addition to the quoted price, the valuation of our equity investment in Wheels Up considered certain unobservable inputs, including Wheels Up's financial projections, using both market and income approach valuation techniques. Fair value measurement using unobservable inputs is inherently uncertain, and a change in significant inputs could result in different fair values. See Note 4, "Investments," for further information on the transaction with Wheels Up and our other equity investments.

Fuel Hedge Contracts. Our derivative contracts to hedge the financial risk from changing fuel prices are primarily related to inventory at our wholly-owned subsidiary, Monroe Energy, LLC ("Monroe"). Our fuel hedge portfolio may consist of a combination of options, swaps or futures contracts, most of which have a duration of less than three months. Option and swap contracts are valued under income approaches using option pricing models and discounted cash flow models, respectively, based on data either readily observable in public markets, derived from public markets or provided by counterparties who regularly trade in public markets. Futures contracts and options on futures contracts are traded on a public exchange and valued based on quoted market prices. We recognized losses of $140 million and $96 million on our fuel hedge contracts in aircraft fuel and related taxes on our Condensed Consolidated Statements of Operations and Comprehensive Income ("income statement") for the three and nine months ended September 30, 2023, respectively, compared to gains of $139 million and losses of $339 million for the three and nine months ended September 30, 2022, respectively. The losses recognized during the first nine months of 2023 were composed of $59 million of mark-to-market gains and $155 million of settlement losses on contracts. Gains and losses on settled contracts are reflected within Monroe's operating results. See Note 9, "Segments," for further information on our Monroe refinery segment.

Notes to the Condensed Consolidated Financial Statements
NOTE 4. INVESTMENTS

We have developed strategic relationships with a number of airlines and airline services companies through joint ventures and other forms of cooperation and support, including equity investments. Our equity investments reinforce our commitment to these relationships and generally enhance our ability to offer input to the investee on strategic issues and direction, in some cases through representation on the board of directors.

Fair Value Investments. Changes in the valuation of investments accounted for at fair value are recorded in gain/(loss) on investments, net in our income statement within non-operating expense and are driven by changes in stock prices, foreign currency fluctuations and other valuation techniques for investments in certain companies, particularly those without publicly-traded shares.

Equity Method Investments. We record our share of our equity method investees' financial results in our income statement as described in the table below.

Wheels Up. We, along with Certares Management LLC, Knighthead Capital Management LLC and Cox Enterprises, Inc. announced the closing on September 20, 2023 of an expanded strategic partnership with Wheels Up, which includes an agreement for a $500 million credit facility to Wheels Up. At closing, the credit facility was comprised of a $350 million term loan, of which we contributed $150 million, and a $100 million liquidity facility that we made available to Wheels Up in the event the company's liquidity falls below $100 million. The terms of the credit facility permit one or more new lenders to provide an aggregate incremental $50 million term loan after the closing date. In connection with the closing, the term loan investors received newly issued shares of Wheels Up's common stock representing 80% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis. Upon approval by Wheels Up's stockholders of an amendment to its certificate of incorporation, Wheels Up is expected to issue to the lenders additional new shares such that the lenders will own 95% of Wheels Up's outstanding equity as of the closing of the credit facility on a fully diluted basis.

The $150 million cash contribution was reflected as an investing outflow in our Condensed Consolidated Statement of Cash Flows and allocated on a relative fair value basis to a loan receivable within other noncurrent assets and an equity investment on our balance sheet. Combined with our previous ownership stake, this new investment provides us with a 39% equity stake in Wheels Up calculated based on Wheels Up's outstanding equity as of September 20, 2023. Our current percentage ownership does not reflect the anticipated dilutive effect from the additional shares to be issued to the lenders (including potentially to one or more new lenders under the term loan) upon approval by Wheels Up's stockholders and common stock grants expected to be made under Wheels Up's equity compensation plans. Furthermore, Delta's voting rights with respect to its Wheels Up equity stake are capped at 29.9%.

Notes to the Condensed Consolidated Financial Statements
As a result of the transaction, we concluded that Wheels Up is a variable interest entity ("VIE"). A VIE requires consolidation by the entity’s primary beneficiary. We determined that we are not the primary beneficiary after assessing the decision-making process for the significant activities of Wheels Up, concluding that Wheels Up's Board of Directors continues to possess the decision-making authority over the significant activities, and we do not control Wheels Up's Board. Based on this assessment, Wheels Up is not consolidated in our financial statements.

We continue to account for our equity interest under the fair value option, as originally elected as part of our initial acquisition of Wheels Up shares in 2020. We will also account for our loan receivable at fair value, as the fair value option is applied to all of an investor's financial interests in the same entity. None of the $100 million liquidity facility has been drawn as of September 30, 2023.

Availability Under Revolving Credit Facilities

As of September 30, 2023, we had approximately $2.8 billion undrawn and available under our revolving credit facilities. In addition, we had approximately $400 million outstanding letters of credit as of September 30, 2023 that did not affect the availability of our revolving credit facilities.

Early Settlement of Outstanding Notes

During the nine months ended September 30, 2023, we repurchased a principal amount of $1.4 billion of various secured and unsecured notes and a portion of the SkyMiles Term Loan on the open market and made early principal repayments of $585 million on various notes secured by aircraft. These payments resulted in a $63 million loss on extinguishment of debt recorded in non-operating expense in our income statement.

Aircraft Orders

During the June 2023 quarter, we agreed to acquire one A330-900 with delivery expected to occur in 2025. We also exercised purchase rights for 12 A220-300 with delivery expected to start in 2027.

Legal Contingencies

We are involved in various legal proceedings related to employment practices, environmental issues, commercial disputes, antitrust and other regulatory matters concerning our business. We record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount of loss can be reasonably estimated. Although the outcome of the legal proceedings in which we are involved cannot be predicted with certainty, we believe that the resolution of current matters will not have a material adverse effect on our Condensed Consolidated Financial Statements.

Employees Under Collective Bargaining Agreements

In the March 2023 quarter, Delta pilots ratified a new four-year Pilot Working Agreement effective January 1, 2023. The agreement includes numerous work rule changes and pay rate increases during the four-year term, including an initial pay rate increase of 18%. The agreement also includes a provision for a one-time payment made upon ratification in the March 2023 quarter of $735 million. Additionally, we recorded adjustments to other benefit-related items of approximately $130 million. These items are recorded within pilot agreement and related expenses in our income statement.

NOTE 9. SEGMENTS

Refinery Operations

Our refinery segment operates for the benefit of the airline segment by providing jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. The refinery's production consists of jet fuel, as well as non-jet fuel products. We use several counterparties to exchange non-jet fuel products produced by the refinery for jet fuel consumed in our airline operations. The gross fair value of the products exchanged under these agreements during the three and nine months ended September 30, 2023 was $519 million and $1.8 billion, respectively, compared to $834 million and $2.6 billion for the three and nine months ended September 30, 2022, respectively.

Segment Reporting

Segment results are prepared based on our internal accounting methods described below, with reconciliations to consolidated amounts in accordance with GAAP.

Fair Value Obligations

The net fair value obligations presented in the table above are related to renewable fuel compliance costs and presented net of any related assets or fixed price purchase agreements. Their value is based on quoted market prices and other observable information and are therefore classified as Level 2 in the fair value hierarchy. Our obligation as of September 30, 2023 was calculated using the U.S. Environmental Protection Agency's ("EPA") Renewable Fuel Standard ("RFS") volume requirements, which were finalized in 2022 for the 2021 and 2022 obligations, and proposed in 2022 for 2023 obligations. In the March 2023 quarter, we settled a portion of our 2021 Renewable Identification Numbers ("RINs") obligation with the EPA. We expect to settle the remaining 2021 and our entire 2022 RINs obligation by the 2022 compliance deadline in the December 2023 quarter.

NOTE 10. EARNINGS PER SHARE

We calculate basic earnings per share by dividing net income by the weighted average number of common shares outstanding, excluding restricted shares. We calculate diluted earnings per share by dividing net income by the weighted average number of common shares outstanding plus the dilutive effect of outstanding share-based instruments, including stock options, restricted stock awards and warrants. Antidilutive common stock equivalents excluded from the diluted earnings per share calculation are not material. The following table shows the computation of basic and diluted earnings per share:

Item 2. MD&A
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Condensed Consolidated Financial Statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our audited Consolidated Financial Statements and related notes included in our 2022 Form 10-K.

September 2023 Quarter Financial Highlights

Our operating income for the September 2023 quarter improved $528 million compared to the September 2022 quarter to $2.0 billion for the reasons discussed below.

Revenue. Compared to the September 2022 quarter, our total revenue increased $1.5 billion, or 11%, due primarily to a 16% increase in capacity driven by strength in the demand for premium products and international travel. Total revenue, adjusted (a non-GAAP financial measure) increased in the September 2023 quarter by $1.7 billion, or 13%, compared to the September 2022 quarter. Adjustments were primarily to exclude revenue related to refinery sales to third parties.

Operating Expense. Total operating expense in the September 2023 quarter increased $1.0 billion, or 8%, compared to the September 2022 quarter, primarily due to higher employee costs from increased wages and profit sharing, higher maintenance costs and increased costs associated with higher capacity, partially offset by lower fuel expense and lower expenses related to refinery sales to third parties, reflected in ancillary businesses and refinery
