COMMERCIAL AVIATION Airbus flew the A321neo for the first time Feb. 9, from Hamburg, after a last-minute switch to an aircraft with CFM International Leap-1A engines rather than the Pratt & Whitney PW1100G-powered jet planned. The Pratt-engined A321neo is still to be delivered first, by the end of 2016, and the CFM-powered version by early 2017. Boeing may be nearing the decision on an aircraft to potentially fill the gap between the 737 MAX and 787.
