TOKYO (AP) — ANA is ordering 70 aircraft with a list price of 1.7 trillion yen ($17 billion) from Boeing Co. and Airbus, in the largest order in the Japanese carrier’s history.

Thursday’s orders underline ANA’s ambitions to become a leading airline and Japan’s tourism drive leading up to the 2020 Tokyo Olympics.

The jets, being delivered from fiscal 2016 through fiscal 2027, will increase the ANA fleet to 250 jets, including 14 orders of Boeing’s medium-sized 787-9 Dreamliner.

The 787 was grounded last year while the plane’s safety was checked for battery problems.

From Airbus, ANA is ordering 30 smaller single-aisle jets from the A320 family.

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