AirAsia X has ordered 150 Airbus A220 aircraft powered by Pratt & Whitney GTF engines, with deliveries starting in 2028, according to a company statement. The order includes a 12-year EngineWise Comprehensive service agreement for engine maintenance.

Pratt & Whitney, a business unit of RTX (NYSE: RTX), will provide the engines and maintenance services for the aircraft order. The A220 fleet will have a range of up to seven hours and is designed to serve medium-haul routes.

"This order reflects the airline's confidence in the GTF engine and its unmatched fuel efficiency and smaller noise footprint," said Rick Deurloo, president of Commercial Engines at Pratt & Whitney.

Bo Lingam, Group CEO of AirAsia X, stated that the aircraft will enable the airline to "build the biggest and densest network" and open up new route possibilities with right-sized capacity.
