United Airlines has long relied on the Boeing 767 as a crucial component of its fleet, particularly for transatlantic routes and high-capacity domestic flights. The airline's use of the Boeing 767 differs from competitors like Delta Air Lines, which also deploys the aircraft for premium transcontinental services.
The Boeing 767, introduced in 1982, is a mid-size wide-body twin-engine airliner with a capacity ranging from 181 to 269 passengers. It features a two-crew glass cockpit shared with the Boeing 757, allowing for operational flexibility. The aircraft's ETOPS certification enables it to perform extended-range services over large bodies of water.
As of May 2025, United Airlines operates over 1,000 mainline aircraft, including narrowbody A320 family jets and new MAX models from the Boeing 737 family. The airline's widebody fleet includes Boeing 777s and Dreamliners, which will become more prominent as part of United's "United Next" modernization strategy. This strategy involves ordering over 500 new Boeing 787s to replace older models like the Boeing 767 by 2030.
