United Airlines has taken delivery of the first aircraft powered by Pratt & Whitney GTF Advantage engines. The Airbus A321XLR was handed over on September 24, 2026, with Pratt & Whitney marking the milestone at its East Hartford, Connecticut, site. United is the global launch customer for the GTF Advantage engine standard, a new variant of the PW1100G-JM.
The GTF Advantage features a redesigned hot section – the part of the engine exposed to the highest thermal loads, including the combustor and turbine. Pratt & Whitney describes it as the most advanced hot section in the single-aisle market. According to the manufacturer, the engine is designed to deliver up to twice the time on wing compared with the current GTF, allowing it to remain in service for longer between required shop visits.
It also provides 4 to 8 percent more takeoff thrust. Pratt & Whitney says the resulting increase in range capability is particularly relevant to the long-range mission profile of the A321XLR.
PW1100G-JM production to transition by 2028
According to Pratt & Whitney, the GTF Advantage is fully intermixable and interchangeable with the existing GTF model. The company plans to transition the entire PW1100G-JM production line to the Advantage specification by 2028.
For PW1100G-JM engines already in service, Pratt & Whitney is also offering the GTF Hot Section Plus (HS+) upgrade. It is expected to provide 90 to 95 percent of the durability benefits of the GTF Advantage and will be available from early 2027 during regular maintenance visits.
“United will be the first airline to benefit from the efficiency, increased durability and additional thrust capability of the GTF Advantage,” said Rick Deurloo, President Commercial Engines at Pratt & Whitney. He added that the engine is particularly well suited to the A321XLR.
Ankit Gupta, Senior Vice President and Chief Air Operations Officer at United Airlines, pointed to the companies’ long-standing relationship. GTF-powered aircraft, he said, are helping United reduce fuel burn and improve reliability as the airline adds new destinations to its network.
