All Nippon Airways (ANA) will join Japan Airlines (JAL) in resuming Boeing 787 operations on 1 June.
The aircraft type will be used on routes from Tokyo Narita to San Jose, and from Tokyo Haneda to Frankfurt and Beijing.
On 1 June, ANA will deploy the 787 on the Tokyo Haneda-Taipei Songshan and Tokyo Nartia-Beijing routes. The 787 will also replace the 767-300ER on the Tokyo Narita-Shanghai Pudong service starting 1 August.
The airline intends to use the 787s on services from Tokyo Haneda to Akita and Toyama, starting 1 and 15 June respectively. It also intends deploy the aircraft type on additional domestic flights from July, primarily on services to Okinawa.
Domestic destinations previously served by the aircraft type will also resume in June, says an airline spokesman.
Meanwhile, its Tokyo Narita-Seattle services - which were suspended as a result of the 787 groundings - will resume on 1 June using Boeing 777-300ER aircraft.
ANA and JAL are in the process of changing their 787s' main and auxiliary lithium-ion batteries, as well as adding new containment and venting systems. Both expect modifications to be completed by mid-May.
Data from Flightglobal Pro shows that ANA has received 17 787-8s, with an additional 19 -8s and 30 787-9s on order. JAL, meanwhile, has seven -8s in its fleet, with an additional 18 -8s and 20 787-9s on order.
