United gets its first plane with new engines. They can stay on board up to twice as long as today's model.
RTX's Pratt & Whitney delivered its first GTF Advantage-powered Airbus A321XLR to United Airlines on September 24, 2026. The engine offers up to twice the time on wing and 4-8% more takeoff thrust than current GTF engines. Pratt & Whitney plans to transition its entire PW1100G-JM production line to the Advantage specification by 2028. United Airlines will be the first to benefit from the engine's efficiency and durability.
