The move is part of the carrier’s long-haul fleet modernisation strategy.
“The B777-9X promises us improved payload range capability and reduced operating costs, in addition to a significant reduction in environmental emissions,” explains John Slosar, chief executive of Cathay Pacific Airways.
“We think it will be an ideal fit for long-haul destinations in North America and Europe.”
The B777X programme generated a record 259 orders and commitments worth $95bn at list prices at the Dubai Airshow– the largest product launch in commercial jetliner history by value, says a Boeing statement. The first deliveries will be in 2020.
“Cathay Pacific and Boeing share a long-term partnership that spans four decades," adds Ray Conner, Boeing's Commercial Airplanes president and chief executive.
"We are honoured to continue our tradition of launching new airplane models with Cathay Pacific in Asia, starting with the Rolls Royce-powered B747-400 and the original B777-200s, B777-300s, B777-300ERs and naturally, now with the B777X family."
Slosar continues: “The B777-300ER has done a superb job for us and Cathay Pacific is now the second largest operator of this type. We are now delighted to be an early customer for this next generation of the B777 aircraft.”
The Hong Kong flag-carrier operates 55 B777s, including 38 B777-300ERs and a freighter fleet that includes 13 B747-8Fs.
