What's New in United's Fleet — 2026
- 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 425 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.
