United Airlines fleet

From Wikipedia, the free encyclopedia
This article is about the mainline United Airlines fleet, including the historical fleets of United Airlines. For information about the fleet of United's regional operations, see United Express § Fleet.

As of December 2024, the United Airlines fleet consists of 991 mainline aircraft, making it one of the two largest commercial airline fleets in the world, along with Delta Air Lines.[1][2][3] United Airlines operates a mix of Airbus and Boeing narrow-body and all Boeing wide-body aircraft. Additionally, United operates more widebody aircraft than any other U.S. carrier.[4]

With an average age of 16.3 years, United has the oldest fleet of all major US airlines.[citation needed] Their oldest planes are the Boeing 767-300ER from the early 1990s, which are between 30 and 32 years old;[citation needed] however, United recently[when?] placed several orders for new narrow-body and wide-body aircraft and are expecting over 700 new planes in their fleet by 2033.

Fleet strategy

[edit]

On July 20, 2011, American Airlines announced an order for 460 narrow-body jets, including 260 Airbus A320s.[5] This order broke Boeing's monopoly with the airline and forced Boeing to proceed with plans for the re-engined 737 MAX.[6] The contract with American included a Most-Favoured-Customer Clause, which requires Airbus to refund to American any difference between the price paid by American and the price paid by United or another airline, if lower. The clause acts to perpetuate United having a Boeing-skewed fleet.[7]

On September 22, 2012, United became the first American airline to take delivery of the Boeing 787 aircraft.[8] United is also the North American launch customer for the Boeing 787-9[9] and 787-10 aircraft,[10] which are stretched versions of the base 787-8 model, delivered at launch.

In May 2018, United planned to replace its 51 Boeing 767s in a deal potentially worth $14 billion at list prices, and was in talks with both Airbus and Boeing, for their A330neo and 787.[11] United operates 128 757s and 767s (77 757s and 51 767s), the second-largest combined fleet after Delta Air Lines with 206 (127 757s and 79 767s). Both have to replace them; they could be replaced by 737 MAX 10s, A321neos, Boeing NMAs, 787-8s, or A330neos.[12]

On June 3, 2021, United announced that a deal had been confirmed with Boom Supersonic to purchase at least 15 of their Overture supersonic airliners and potentially up to 50 in total. These aircraft will be flown on 100% sustainable fuels. The aircraft is intended to enter service with United in 2029 and is expected to be the first supersonic airliner to fly domestically for an airline since the Concorde was retired with British Airways and Air France in 2003.[13]

On June 29, 2021, United announced an order for 270 aircraft valued at around $15 billion: 150 737 MAX 10 aircraft, 50 737 MAX 8 aircraft, and 70 A321neo aircraft.[14] United also announced the rollout of the "Signature Interior" which will include video screens on every seat. New aircraft will enter the fleet with the Signature Interior, while all mainline aircraft will be retrofitted with the interior by 2025.[15] United has also announced the retirement of older mainline aircraft and at least 200 single-class regional aircraft.
