Japan Airlines said Wednesday it has selected Boeing Co.'s new 7E7 passenger jet to replace a fleet of older aircraft -- the latest development in the rivalry between the U.S. aircraft maker and Europe's Airbus to woo Asian carriers.

Japan Airlines said it will purchase 30 of Chicago-based Boeing's planned aircraft, called the 7E7 Dreamliner, with an option to order 20 more of both the long-range 7E7-8 and the short-to-medium-range 7E7-3.

JAL spokesman Tatsuo Yoshimura said the price of the deal was not disclosed, but said the catalog price for 30 7E7 jets is estimated at 430 billion yen.
