Delta said that its consolidation of Tokyo flights at Haneda Airport beginning March 28 will still happen as planned. Flights between Seattle, Detroit, Atlanta, Honolulu and Portland will transition from Narita to Haneda beginning March 28 for departures from the U.S. to Tokyo, and March 29 for departures from Tokyo to the U.S. Delta’s Tokyo-bound flights from Minneapolis and Los Angeles already fly into Haneda and will continue to do so.
Delta’s service between Narita and Manila will continue to operate daily until March 27, after which the flight will be suspended as part of the carrier’s previously-announced consolidation at Haneda. The airline’s new service from Incheon to Manila, previously scheduled to begin March 29, will now start on May 1.
The airline’s seasonal summer service between Seattle and Osaka will be suspended for the summer of 2020, with a planned return in summer 2021. Delta will continue to serve Osaka from Honolulu.
Full schedules will be available March 7.
