Japan Airlines has postponed the planned March start of direct daily service between San Diego and Tokyo, due to the continued global grounding of the Boeing 787 aircraft. The airline announced that four-days-weekly service will be offered from San Diego International Airport during the month of March.

Inbound and outbound flights are scheduled for Mondays, Wednesdays, Fridays and Sundays for the March 1-30 period, except for March 27, according to a statement from the carrier. Schedules for March 31 and beyond have not yet been finalized.

The carrier’s schedule revision prompted cancelation of a total of 28 local flights previously slated for Tuesdays, Thursdays and Saturdays during March, impacting approximately 1,800 passengers.

“We sincerely apologize to all customers and related parties for the inconvenience and concerns caused by recent issues with the Boeing 787 aircraft,” Japan Airlines spokeswoman Carol Anderson said in an email.

The San Diego region’s first-ever direct service to Asia started in December with four-days-weekly service, which was originally scheduled to become daily on March 1. The Boeing Dreamliner grounding, prompted by electrical system issues, forced cancelation of 22 local flights that had been slated for January and February.

Japan Airlines since late January has been operating the local international flights with the larger Boeing 777 aircraft.
