Boeing and Cathay Pacific today announced the Hong Kong-based carrier is ordering 14 more B-777/9 passenger jets, bringing its order book to 35 of the twin-engine airplane.

Designed to reduce fuel use and emissions on average by 20% and noise by 40% compared to the airplanes it replaces, the B-777/9 will enable Cathay Pacific to efficiently meet growing air travel demand across key global markets.

The carrier has grown its global network with the B-777 family over the past 30 years. The addition of the latest model, the 777/9, will further reduce the airline's operating costs as it modernizes its fleet and expands passenger and cargo operations on long- and ultra long-haul routes.

With a range of 7,295 nautical miles (13,510 km), the model will allow Cathay Pacific to connect passengers directly between Hong Kong and its global long-haul destinations. Customers around the world have ordered more than 550 B-777X airplanes, sustaining thousands of jobs at Boeing's Everett, Wash., site and across the supply chain.
