The largest Asian airline said Monday it would keep its current, lower capacity levels beyond the original April 26 expiration date by at least another four weeks.
Japan Airlines is currently flying five of its usual six daily flights to Hawaii, having suspending only its third daily flight from Tokyo Narita.
That leaves two flights from Tokyo Narita plus one apiece from Tokyo Haneda, Osaka Kansai and Nagoya.
JAL also scaled back flights to Beijing, Seoul, Taipei and other cities, and the airline says Narita flights to Hong Kong will be suspended entirely through the end of May.
British Airways, meanwhile, announced Monday it is suspending flights to Tokyo Haneda "until further notice." It still flies to Tokyo Narita.
