United Airlines fleet

From Wikipedia, the free encyclopedia

As of June 2026, the United Airlines fleet consists of 1,107 mainline aircraft,[1] the largest of any airline worldwide. United Airlines operates a mix of narrow-body aircraft from Airbus and Boeing and all Boeing wide-body aircraft with more wide-bodies than any other North American passenger airline.[2][3] The average age of United's fleet is 15.2 years.[1]

Strategy

The "United Next" strategy introduced during the COVID-19 pandemic is United Airlines' plan to modernize and expand its fleet while enhancing operational efficiency and the passenger experience. Unlike other major U.S. airlines, United retained its wide-body aircraft during the pandemic, allowing the airline to meet the surge in travel demand, especially internationally as recovery progressed.[4]

Since 2021, United has placed orders for over 500 various narrow-body jets and 150 wide-body Boeing 787 Dreamliner jets as part of its strategy, which also includes retiring older mainline aircraft and at least 200 single-class regional jets.[5][6][7]

The strategy emphasizes improving the passenger experience. United's "Signature Interior" concept features seatback entertainment systems with Bluetooth connectivity, power outlets at every seat, and larger overhead bins designed to accommodate a roller bag for each passenger. All new aircraft will include the updated interior, with retrofitting of existing mainline aircraft expected to be completed by 2025.[8] United has also selected SpaceX's Starlink as its in-flight internet connectivity provider for mainline and two-class regional aircraft. This high-speed, low-latency satellite internet service will enable live streaming, cloud-based work applications, and gaming with complimentary access provided to all passengers.[9]

United Airlines has also invested in and secured options for several aircraft under development. These include options to purchase 100 eVTOL (electric vertical takeoff and landing) aircraft from Archer Aviation[10] and 200 eVTOL aircraft from Eve Air Mobility, a division of Embraer.[11] Furthermore, the airline has committed to purchasing 100 ES-30 electric turboprop regional aircraft from Heart Aerospace, with options to purchase up to 50 more.[12] United has also committed to purchasing 15 Boom Overture supersonic aircraft, with options to purchase up to 35 more.[13]
