CY2022	us-gaap	Property Plant And Equipment Impairment PropertyPlantAndEquipmentImpairment	We review flight equipment, ROU assets and other long-lived assets used in operations for impairment losses when events and circumstances indicate the assets may be impaired. Factors which could be indicators of impairment include, but are not limited to (1) a decision to permanently remove flight equipment or other long-lived assets from operations, (2) significant changes in the estimated useful life, (3) significant changes in projected cash flows, (4) permanent and significant declines in fleet fair values and (5) changes to the regulatory environment. For long-lived assets held for sale, we discontinue depreciation and record impairment losses when the carrying amount of these assets is greater than the fair value less the cost to sell. <div style="text-indent:13.54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">To determine whether impairments exist for aircraft used in operations, we group assets at the fleet type level or at the contract level for aircraft operated by third-party regional carriers (i.e., the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity, passenger mile yield, fuel and labor costs and other relevant factors. If an asset group is impaired, the impairment loss recognized is the amount by which the asset group's carrying amount exceeds its estimated fair value. We estimate aircraft fair values using published sources, appraisals and bids received from third parties, as available. Due to the impacts of the COVID-19 pandemic, during 2020 we removed a significant portion of our mainline and regional aircraft from active service and evaluated our fleet for impairment, determining that only certain fleet types were impaired, as the future cash flows from the operation of these fleet types through the respective retirement dates were lower than the carrying value. </span></div><div style="text-indent:13.54pt"><span><br/></span></div><div style="text-indent:13.54pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Due to the recovery in demand that we experienced throughout 2021 and 2022, we decided not to retire any additional aircraft and returned to service a majority of the aircraft that were temporarily parked in 2020. We recorded no further impairments during 2021 or 2022. See Note 15, "Government Grants and Restructuring," for additional details regarding these impairments and related charges.</span></div>
