In the latest blow to Boeing, Japan’s All Nippon Airways (ANA) will cancel all Boeing 787 flights until at least the end of May.
Aviation regulators grounded all 787 Dreamliners in January so that safety checks could be carried out on the aircraft’s batteries.
ANA is cancelling more than 1,700 flights in April and May, a period that includes Japan’s Golden Week holiday, the BBC reported.
Of the newly announced cancellations, 1,250 are domestic and 464 are international flights, including those bound for Seoul, Seattle and Frankfurt.
ANA is Boeing’s biggest Dreamliner customer, with 17 of the world’s 50 operational 787s.
Boeing’s entire fleet of Dreamliners was grounded after a battery on a Japan Airlines 787 caught fire, and a malfunction forced an ANA flight to make an emergency landing.
Investigations into the battery have so far proved inconclusive.
Last week, Boeing gave US regulator, the Federal Aviation Administration (FAA), its plan to fix the battery problems, which reportedly involves a significant redesign of the battery pack.
The FAA is reviewing the plan.
