The orders from Boeing and Airbus are worth $2.3bn and $1.99bn respectively, according to list prices, but airlines typically get large discounts.
The purchase is the first in Japan for Boeing’s latest edition of its best-selling 737 model, and comes as the country faces pressure from US President Donald Trump to cut its trade surplus with the United States.
ANA was the first Japanese firm to pick Airbus’ narrowbody plan five years ago, and has now ordered 18 of the A320neo model, the newest version of the A320 jet popular with Japan’s low-cost airlines.
“The decision was based on the economic growth of Asia and emerging countries, with demand in the Asian aviation market and inbound demand on the rise,” ANA said of the fresh orders.
Deliveries of the planes are pencilled in to begin in 2021, stretching through until 2025. ANA said it also had options for another 10 of Boeing’s jets.
Earlier this month it emerged Boeing had pipped its arch-rival Airbus to the post in the race for the most aircraft orders in 2018 for the first time in six years. Boeing had 893 orders against Airbus’ 747, while the American firm also won the race to the most deliveries for the seventh straight year.
