(a) United also has options and purchase rights for additional aircraft.
(b) Contractual aircraft deliveries reflect an agreement United entered into with Airbus on July 16, 2024 to adjust delivery schedules for the A321neo ("Airbus Agreement").
(c) Expected aircraft deliveries reflect adjustments to contractual delivery schedules as communicated by Boeing and Airbus or estimated by United. However, aircraft deliveries are subject to a number of variables, as further described in Part I, Item 1A. Risk Factors of the 2023 Form 10-K, and we cannot guarantee delivery of any particular aircraft at any specific time notwithstanding firm purchase commitments.
Schedule of Commitments | The table below summarizes United's firm commitments as of June 30, 2024, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments communicated by Boeing and Airbus or estimated by United but reflecting the Airbus Agreement and the April 14, 2024 arrangements between United and Boeing.
