Japan Airlines Co <9201.T> may buy about 20 A350 jets from Airbus for around 400 billion yen ($4.23 billion), the Nikkei daily reported on Sunday, a move that would reduce its reliance on Boeing .
The Japanese carrier is considering using A350-1000 jets on flights to Europe and the United States to replace its Boeing 777 jets, and is set to make a final decision on the purchase by around June, the newspaper said, without citing sources.
Japan Airlines and Airbus could not be immediately reached for comment.
The deal for the 350-seater planes would be the first with the European aircraft maker and includes a simulation facility for pilot training.
Japan Airlines is set to retire its lone McDonnell Douglas MD-90 jet after a final flight on March 30, leaving it with a fleet of more than 100 aircraft, all manufactured by Boeing, the report said.
The carrier's seven Boeing 787 Dreamliner jets have been grounded since mid-January after problems with its lithium-ion battery.
