Boeing and Cathay Pacific Airways celebrated a significant achievement on Sept. 25, 2015, with the delivery of the airline's 70th 777 aircraft that has made Cathay Asia's largest operator of the 777 fleet.

With this delivery, Cathay Pacific's 777 aircraft fleet comprises of 53 777-300ERs, 12 777-300s and five 777-200s. The airline is one of the launch customers for the 777X with 21 777-9 airplanes on order.

"The 777s have played an important role in Cathay Pacific's fleet modernization and network expansion strategy," said Ivan Chu, Chief Executive, Cathay Pacific Airways. "We operate the largest 777 fleet in Asia, and these aircraft offer the range, reliability and flexibility to build multiple daily frequencies on trunk routes, both within the Asia-Pacific region and, with the 777-300ERs, on long-haul and ultra-long-haul routes. Our 777 fleet has helped in our efforts to reinforce Hong Kong's position as one of the world's most important international aviation hubs."
