BBC News - Airbus and Japan Airlines agree landmark $9.5bn deal
The deal is a blow for Boeing, which has dominated Japan's aviation market.
"This is Airbus' largest order for the A350 so far this year and is the largest ever order we have received from a Japanese airline," said Fabrice Bregier, chief executive of Airbus.
"I must say that achieving this breakthrough order and entering a traditional competitor market was one of my personal goals."
According to the deal, JAL also has an option to purchase an additional 25 planes.
