Japan Airlines has been identified as the customer for four Boeing 787-8s that were previously attributed to an unidentified customer.
Boeing says that the deal is valued at more than $900 million at list prices.
JAL president Yoshiharu Ueki says that the order is part of its efforts to bolster its network ahead of Tokyo hosting the 2020 Olympic Games.
"The superior noise performance of the 787 will play a critical role in meeting our commitment for quieter operations within our domestic network going forward," he adds.
Flight Fleets Analyzer shows that JAL already operates a fleet of 25 787-8s and nine -9s, while it has 11 more of the latter on order. All of its 787s are powered by General Electric GEnx engines.
With JAL now identified, Boeing’s orders and deliveries website shows that there are 27 787s attributed to unidentified customers.
