All Nippon Airways (ANA) has ordered another 11 Boeing 787-9s.
The aircraft will be delivered between the 2018 and 2021 fiscal years, says the Japanese carrier.
This brings its total order for the 787 aircraft to 66, divided between 36 787-8s and 30 787-9s. Boeing has delivered 13 787-8s to the aircraft's launch customer.
All of ANA's existing 787s are powered by the Rolls-Royce Trent 1000, although the airline has not revealed an engine selection for its new order.
"ANA's future fleet plans involve the gradual replacement of the Boeing 767 and Boeing 777-200 with the 787. The fuel efficiency of the 787-9 is similar to that of the 787-8, while it has more seats, helping support the profitable expansion of ANA's international and domestic route networks," says the airline.
ANA is using the aircraft on eight domestic Japanese routes and on the Tokyo Haneda-Frankfurt route. It plans to launch a new service from Tokyo Narita to San Jose service in January.
The carrier will switch to operating 787s on its Narita-Seattle service from 1 October and its Haneda-Beijing route from 28 October.
