7. LEASES

The Company enters into leases for aircraft, property, and other types of equipment in the normal course of business. As allowed under ASC 842, Leases, the Company has elected a practical expedient to exclude from recognition lease assets and lease liabilities associated with leases that have an initial term of twelve months or less. Such expense was not material for the twelve months ended December 31, 2025, 2024, and 2023.

As of December 31, 2025, the Company held aircraft leases with remaining terms extending up toeight years. The aircraft leases generally can be renewed forthree months tothree years at rates based on the fair market value at the end of the lease term. Residual value guarantees included in the Company's lease agreements are not material. The lease return costs incurred by the Company for returns completed in 2025 were $33 million, recognized as a component of Other operating expenses but werenot material for all other periods presented.

In fourth quarter 2024, the Company entered into an agreement with UMB Bank, N.A.

Of the 36 -800 sale-leasebacks,35 were executed in fourth quarter 2024 andone was executed in first quarter 2025. The Company sold the 35 -800 aircraft in fourth quarter 2024 to UMB Bank for $871 million, then immediately leased the aircraft back for approximatelytwo tothree years. In first quarter 2025, the Company soldone -800 aircraft to UMB Bank for $24 million, then immediately leased the aircraft back for approximately three years. As such,36 aircraft were de-recognized from Property and equipment at their remaining net book values at the time of sale. All of the leases from the sale-leasebacks are accounted for as operating leases, and thus are now reflected as part of the Company’s Operating lease right-of-use assets and operating lease liabilities in the accompanying Consolidated Balance Sheet. The -800 sale-leaseback transaction resulted in a recognized gain of $92 million and operating lease right-of-use assets and liabilities of $319 million in fourth quarter 2024 and resulted in a recognized gain of $3 million and operating lease right-of-use assets and liabilities of $9 million in first quarter

2025. These gains were reflected within Other operating expenses, net in the accompanying Consolidated Statement of Comprehensive Income.

The Company paid the lessors $45 million in 2024, of which $3 million was recorded as the elimination of the Company's remaining finance lease obligation for the aircraft, and which was also reflected within Payments of long-term debt and finance lease obligations in the accompanying Consolidated Statement of Cash Flows and $2 million was recorded as the elimination of the Company's remaining operating lease obligation for the aircraft, and which was also reflected within Changes in Other noncurrent assets in the accompanying Consolidated Statement of Cash Flows.
