Singapore Airlines committed to purchase 20 777-9s and 19 787-10 Dreamliners from Boeing. The national carrier and 787-10 launch customer also recommitted to its previous order for 30 787-10 airplanes.

“Singapore Airlines has been a valued Boeing customer for more than 50 years and we are honored they have selected the 777X and additional 787-10s to expand its future widebody fleet. They are the most efficient, capable and passenger preferred airplanes in their class,” said Boeing Commercial Airplanes President and CEO Kevin McAllister. “We appreciate the trust, commitment and endorsement of Singapore Airlines, and look forward to delivering market-leading capability to one of the world’s most widely respected industry leaders.”

Boeing’s goal is for the 777-9 to be the largest and most efficient twin-engine commercial jet in the world with the lowest operating cost per seat of any commercial airplane.

The 787-10 is the third member of the 787 Dreamliner family. Since its introduction, the 787 Dreamliner has opened more than 130 new city pairs.
