Japanese carrier ANA has ordered 70 aircraft with a list price of 1.7 trillion yen ($17 billion) from Boeing and Airbus, the largest order in the airline’s history.

The jets will be delivered over a period of 11 years starting in 2016 and will increase the ANA fleet to 250 aircraft.

ANA has ordered a total of 40 aircraft from Boeing, including 14 787-9 Dreamliners, 20 twin-aisle 777-9X aircraft and six 777-300ER jets. From Airbus, ANA has ordered 30 single-aisle jets from the A320 family, made up of seven A320neo aircraft and 23 A321neo aircraft.

ANA said the 40 new Boeing jets will be used mostly for international flights, while Airbus planes will be for domestic routes.

"These new aircraft will give us maximum flexibility and improved fuel efficiency, and will allow us to meet the growth in demand, both internationally and in our domestic Japanese market," said ANA Holdings president and chief executive Shinichiro Ito.

Boeing welcomed its orders, which total about $13 billion at list prices.
