United Airlines Fleet Database

United Airlines operates one of the world's largest and most diverse fleets, with 1,139 mainline aircraft spanning narrowbody and widebody types from Boeing and Airbus — and it is in the middle of its biggest fleet renewal in decades, taking 250+ new jets by 2028 while rolling out free Starlink WiFi and the new Polaris Studio suite.

• Polaris Studio debuts on the Boeing 787-9. United's newest "Elevated" 787-9 Dreamliners carry eight ultra-premium Polaris Studio suites — sliding privacy doors, 27-inch 4K screens, and a companion seat — giving them the highest premium-seat ratio of any U.S. widebody. In service since April 2026.
• The Airbus A321XLR enters service. United's first long-range single-aisle jet arrived in June 2026 with 20 lie-flat Polaris suites and Premium Plus, replacing the Boeing 757-200 on long, thin transatlantic routes.
• Free Starlink WiFi passes 600+ aircraft. United Express regional jets led the rollout, mainline 737-800s followed in October 2025, and the first widebody Boeing 777 went live in June 2026 — with roughly 1,000 aircraft targeted by year-end.
• The Signature Interior nears completion. Around 70% of the mainline narrowbody fleet now has seatback 4K screens, Bluetooth audio, and larger overhead bins, with new A321neo and 737 MAX jets arriving factory-fit.
• United marks its 100th anniversary in 2026, tracing its roots to Varney Air Lines' first airmail flight on April 6, 1926.

United offers up to four cabin classes depending on the aircraft: Polaris Business Premium Plus Economy Plus and Economy. Polaris lie-flat seats are available on all widebody international aircraft. Select any type above for the full seat configuration guide.
