Delta: Reduced flight frequency
”Delta will reduce its weekly flying schedule to Japan through April 30 and suspend summer seasonal service between Seattle and Osaka for 2020 in response to reduced demand due to COVID-19 (coronavirus).
Delta’s planned consolidation of Tokyo flights at Haneda Airport beginning March 28 will 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.
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 on delta.com beginning March 7. The airline will continue to monitor the situation closely and may make additional adjustments as the situation continues to evolve.”
