Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On January 5, 2024, an Alaska Airlines 737-9 flight made an emergency landing after a mid-exit door plug detached in flight. Following the accident, the Federal Aviation Administration (FAA) grounded and required inspections of all 737-9 aircraft with a mid-exit door plug, which constitute the large majority of the approximately 220 737-9 aircraft in the in-service fleet. On January 24, 2024, the FAA approved an enhanced maintenance and inspection process that must be performed on each of the grounded 737-9 aircraft. Our 737-9 operators have begun returning their fleets to service, and many 737-9s have completed inspections and resumed revenue flights. All 737-9 aircraft in production will undergo this same enhanced inspection process prior to delivery. On January 10, 2024, the FAA notified Boeing that the FAA has initiated an investigation into Boeing’s quality control system. On January 24, 2024, the FAA stated that it will not approve production rate increases or additional production lines for the 737 MAX until it is satisfied that Boeing is in full compliance with required quality control procedures. We are currently unable to reasonably estimate what impact the accident and the related FAA actions will have on our financial position, results of operations and cash flows.
