Japanese airline cancels 177 more Boeing 787 flights

More flights using Boeing's 787 Dreamliner passenger jet were canceled Monday by Japanese airlines as investigators from the U.S. and Japan visited a firm that makes batteries for the plane.

TOKYO — All Nippon Airways said Monday it canceled 151 domestic and 26 international flights scheduled for Jan. 23-28 after Boeing Co.'s 787 Dreamliner passenger plane was grounded, affecting more than 21,000 passengers.

The cancellations add to the 72 flights scheduled for Jan. 19-22 that ANA called off last week.

ANA, which flies the most Dreamliners of any airline, said in a statement it will announce Thursday its plans on flight cancellations for dates from Jan. 29.

Rival Japan Airlines Co. said on Monday it will cancel four flights on its Tokyo-San Diego route for Jan. 27-28, adding to the eight flights originally scheduled for Jan. 19-25 on the same route it called off last week.

Any schedule changes for flights slated for Jan. 26 have yet to be decided, JAL added in a statement.

U.S. and Japanese aviation safety officials investigating the Dreamliner's recent battery-related incidents Monday visited the Kyoto headquarters of GS Yuasa, the firm that makes batteries for the 787, seeking clues into why one of the planes made an emergency landing last week.
