Commitments and Contingencies

Aircraft-Related Commitments and Financing Arrangements

The Company’s contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of June 30, 2014, the Company's aircraft orders consisted of the following:



	Airbus				Third-Party Lessor
	A320	A320NEO	A321	A321NEO	A320NEO	Total
remainder of 2014	8					8

2017	8		10			18
2018	2	6	5			13
2019		3		10		13
2020		13				13
2021		18				18
	29	40	30	10	5	114

The Company also has six spare engine orders for V2500 SelectOne engines with International Aero Engines (IAE) and nine spare engine orders for PurePower PW1100G-JM engines with Pratt & Whitney. Spare engines are scheduled for delivery from 2014 through 2024. Purchase commitments for these aircraft and related flight equipment, including estimated amounts for contractual price escalations and pre-delivery payments, will be approximately $350 million for the remainder of 2014, $658 million in 2015, $601 million in 2016, $757 million in 2017, $615 million in 2018, and $2,207 million in 2019 and beyond. The Company has secured financing commitments with third parties for four aircraft deliveries from Airbus, scheduled for delivery in 2014. The Company does not have financing commitments in place for the remaining 105 Airbus aircraft currently on firm order scheduled for delivery between the fourth quarter of 2014 through 2021. However, the Company has signed letters of intent to finance the remaining 4 aircraft being delivered in 2014 and the first 11 aircraft being delivered in 2015 under secured debt arrangements.

During the first six months of 2014, the Company took delivery of three aircraft which were financed via sale and leaseback transactions with third-party aircraft lessors. The three sale and leaseback transactions resulted in net deferred losses of $1.0 million. Deferred losses are included in other long-term assets on the accompanying balance sheet. Deferred losses are recognized as an increase to rent expense on a straight-line basis over the term of the respective operating leases. Deferred gains are included in deferred credits and other long-term liabilities on the accompanying balance sheet. Deferred gains are recognized as a decrease to rent expense on a straight-line basis over the term of the respective operating leases. The Company had agreements in place prior to the delivery of these aircraft which resulted in the settlement of the purchase obligation by the lessor and the refund of $16.0 million in pre-delivery deposits from Airbus during the six months ended June 30, 2014. The refunded pre-delivery deposits have been disclosed in the accompanying statements of cash flows as pre-delivery deposits for flight equipment, net of refunds, within investing activities. All leases from these sale and leaseback transactions were accounted for as operating leases. Under the terms of the lease agreements, the Company will continue to operate and maintain the aircraft. Payments under the lease agreements are fixed for the term of the lease. The lease agreements contain standard termination events, including termination upon a breach of the Company's obligations to make rental payments and upon any other material breach of the Company's obligations under the leases, and standard maintenance and return condition provisions. These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as additional rent expense when it is probable that such amounts will be incurred. Upon a termination of the lease due to a breach by the Company, the Company would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party. During the fourth quarter of 2013, the Company entered into an agreement for the lease of two quick engine change kits, classified as capital leases. Payments under the lease agreement are fixed for the three year term of the lease.

Future minimum lease payments under capital leases and noncancellable operating leases with initial or remaining terms in excess of one year at June 30, 2014 were as follows:



			Operating Leases
	Capital Leases		Aircraft and Spare Engine Leases		Property Facility Leases		Operating Lease Obligations
	(in thousands)
remainder of 2014	$	923	$	98,287	$	10,272	$	108,559
2015	1,244		197,137		17,256		214,393

Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the related operating leases and is recognized on a straight-line basis. Aircraft rent expense also includes supplemental rent. Supplemental rent is made up of maintenance reserves paid or to be paid to aircraft lessors in advance of the performance of major maintenance activities that are not probable of being reimbursed, and lease return condition obligations which the Company begins to accrue when they are probable and can be estimated. The Company expects supplemental rent to increase as individual aircraft lease agreements approach their respective termination dates and the Company begins to accrue the estimated cost of return conditions for the corresponding aircraft.

Some of the Company’s master lease agreements provide that the Company pays maintenance reserves to aircraft lessors to be held as collateral in advance of the Company’s required performance of major maintenance activities. Maintenance reserve payments are either contractually fixed or utilization based amounts. Fixed maintenance reserve payments for these aircraft and related flight equipment, including estimated amounts for contractual price escalations, will be approximately $3.7 million for the remainder of 2014, $7.6 million in 2015, $8.0 million in 2016, $7.4 million in 2017, $5.8 million in 2018, and $18.4 million in 2019 and beyond. These lease agreements provide that maintenance reserves are reimbursable to the Company upon completion of the maintenance event in an amount equal to the lesser of (1) the amount of the maintenance reserve held by the lessor associated with the specific maintenance event or (2) the qualifying costs related to the specific maintenance event.

On October 15, 2013, the Company had an aircraft experience an engine failure shortly after takeoff. The aircraft immediately returned to the airport, and the passengers and crew safely disembarked from the aircraft. The airframe and engine incurred damage as a result of the failure. In 2013, the Company expensed the insurance deductible related to this incident of approximately $0.8 million. The Company anticipates it will recover insurance proceeds to cover the expenses related to this incident.

Other

The Company is contractually obligated to pay the following minimum guaranteed payments for its reservation system and advertising media as of June 30, 2014: $1.9 million for the remainder of 2014, $3.9 million in 2015, $3.9 million in 2016, $3.9 million in 2017, $2.6 million in 2018, and none in 2019 and thereafter.

Litigation

The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. The Company believes the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on its financial position, liquidity or results of operations.

Credit Card Processing Arrangements

The Company has agreements with organizations that process credit card transactions arising from the purchase of air travel, baggage charges, and other ancillary services by customers. As it is standard in the airline industry, the Company's contractual arrangements with credit card processors permit them, under certain circumstances, to retain a holdback or other collateral, which the Company records as restricted cash, when future air travel and other future services are purchased via credit card transactions. The required holdback is the percentage of the Company's overall credit card sales its credit card processors hold to cover refunds to customers if the Company fails to fulfill its flight obligations. If the Company fails to satisfy certain liquidity and other financial covenants, the processing agreements provide the processors the right to require the Company to maintain cash collateral up to approximately 100% of the Company's air traffic liability, which would result in a commensurate reduction of unrestricted cash. As of June 30, 2014 and December 31, 2013, the Company continued to be in compliance with its credit card processing agreements and liquidity and other financial covenant requirements, and the processors were holding back no remittances.

The maximum potential exposure to cash holdbacks by the Company's credit card processors, based upon advance ticket sales and $9 Fare Club memberships as of June 30, 2014 and December 31, 2013, was $265.5 million and $188.6 million, respectively.

Employees

Approximately 59% of the Company’s employees are covered under collective bargaining agreements. The table below sets forth the Company's employee groups and status of the collective bargaining agreements as of June 30, 2014.



Employee Groups	Representative	Amendable Date	Percentage of Workforce
Pilots	Air Line Pilots Association, International (ALPA)	August 2015	24%
Flight Attendants	Association of Flight Attendants (AFA-CWA)	August 2007	34%
Dispatchers	Transport Workers Union (TWU)	August 2018	1%

In December 2013, with the help of the National Mediation Board (NMB), the Company reached a tentative agreement for a five-year contract with the Company's flight attendants. The tentative agreement was subject to ratification by the flight attendant membership. On February 7, 2014, the Company was notified that the flight attendants voted not to ratify the tentative agreement. The Company will continue to work together with the AFA and the NMB with a goal of reaching a mutually beneficial agreement. On July 8, 2014, ramp service agents directly employed by the Company voted to be represented by the International Association of Machinists and Aerospace Workers (IAM). These ramp service agents currently serve 4 of the 55 airports where the Company operates. The Company is in discussions to begin the process of negotiations with the IAM.

The Company is self-insured for health care claims, up to a stop loss amount for eligible participating employees, and qualified dependent medical claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company has accrued $2.2 million and $2.1 million in health care claims as of June 30, 2014 and December 31, 2013, respectively.
