All Nippon Airways (ANA) of Japan has temporarily cut by half its flights between Seattle and Tokyo, canceling two-way flights Thursday, Saturday and next Monday due to the grounding of its fleet of 17 Boeing 787 Dreamliners.
The largest current user of 787s said in a schedule update Monday it has reduced its daily Seattle flights to every other day, and is using 777s for those flights.
Approximately 150 to 200 passengers are affected by each cancellation, according to data provided by the airline.
Whether there will be additional cancellations beyond that depends upon how long the grounding of the 787s continues, ANA said.
The airline also canceled through Monday its new daily route between Tokyo and San Jose, Calif., except for a flight Thursday.
Since the grounding last week, ANA has canceled a total 51 international flights and 320 domestic flights.
Last Wednesday, an ANA 787 domestic flight made an emergency landing in Japan after a battery overheated and sprayed hot chemicals into the electronics bay.
The airline grounded its 17 Dreamliners shortly afterward.
Regulators in the U.S. and Japan are investigating the cause of that incident and a 787 battery fire a week earlier in Boston.
