All Nippon Airways is extending its fleet of Boeing 787 Dreamliners to more than 100 with a new order for 20 aircraft.

The airline is acquiring an additional 11 B787-10s and four B787-9s on firm order with five options.

The larger B787-10s will be deployed on Japanese domestic routes between 2022 and 2024 as it phases out B777s to cut carbon and noise emissions.

The B787-9s will operate on international routes from 2024 as part of a fleet update following orders for 83 B787s, including 71 in service with the airline.

The value of the latest order was not disclosed.

But the airline said the 787 was selected after a “thorough evaluation process”.

Executive vice president Yutaka Ito said: “Boeing’s 787s have served ANA with distinction and we are proud to expand our fleet by adding more of these technically advanced aircraft.

“These planes represent a significant step forward for ANA as we work to make our entire fleet more eco-friendly and to reduce noise output.

“Introducing the 787-10 on domestic routes will help ANA Group maintain its leadership role and improve our ability to operate as a responsible corporate citizen.”
