SYDNEY—Australia’s Qantas Airways picked Airbus SE over Boeing Co as the preferred supplier for jets capable of the world’s longest commercial flights from Sydney to London, dealing the U.S. planemaker its latest setback this year.
The choice of up to 12 A350-1000 planes fitted with an extra fuel tank for flights of up to 21 hours cements Airbus as the leader in ultra-long haul flights globally at a time when Boeing is battling delays on its rival 777X program and a broader corporate crisis following two deadly 737 MAX crashes.
