Leases [Abstract]  
LEASES LEASES
The Company enters into leases for aircraft, property, and other types of equipment in the normal course of business. The accounting for these leases follows the requirements of ASC 842, Leases.

As of December 31, 2021, the Company held aircraft leases with remaining terms ranging from one month to 12 years. The aircraft leases generally can be renewed for three months to three 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.

On July 9, 2012, the Company signed an agreement with Delta Air Lines, Inc. and Boeing Capital Corp. to lease or sublease 88 AirTran Airways, Inc. Boeing 717-200 aircraft ("B717s") to Delta at agreed-upon lease rates. The Company's future sublease income associated with the 14 remaining B717s on operating lease as of December 31, 2021, was as follows: $17 million in 2022, $7 million in 2023, and $1 million in 2024. There are no contingent payments and no significant residual value conditions associated with the transaction.
In second quarter 2020, the Company entered into transactions with third parties, involving ten of the Company’s Boeing 737-800 aircraft and ten of the Company's Boeing 737 MAX 8 aircraft that qualified as sale-leaseback arrangements under applicable accounting guidance. The Company sold the ten 737-800 aircraft to a third party for $405 million, then immediately leased the aircraft back for approximately ten years. The Company sold the ten 737 MAX 8 aircraft to a third party for $410 million, then immediately leased the aircraft back for approximately 13 years. As such, the aircraft were de-recognized from Property and equipment at their remaining net book values. 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. For 2020, the 737-800 and 737 MAX 8 sale-leaseback transactions resulted in a recognized gain of $153 million and $69 million, respectively, reflected within Other operating expenses, net in the accompanying Consolidated Statement of Income (Loss).

At each airport where the Company conducts flight operations, the Company has lease agreements, generally with a governmental unit or authority, for the use of airport terminals, airfields, office space, cargo warehouses, gates, and/or maintenance facilities. These leases are classified as operating lease agreements and have lease terms remaining ranging from one month to 39 years. Certain leases can be renewed from 1 year to ten years. The majority of the airport terminal leases contain certain provisions for periodic adjustments to rates that depend upon airport operating costs or use of the facilities, and are reset at least annually. Due to the nature and variability of the rates, the majority of these leases are not recorded on the Consolidated Balance Sheet.

The Company also leases certain technology assets, fuel storage tanks, and various other equipment that qualify as leases under the applicable accounting guidance. The remaining lease terms range from three months to five years. Certain leases can be renewed from six months to three years.
