Japan Airlines (JAL) and All Nippon Airways (ANA) have made further cuts to their summer international schedules as demand continues to fall amid the COVID-19 pandemic.

JAL said Apr. 1 that it is suspending 85% of its previously planned flights for the Mar. 29-Apr. 30 period. This is a significant increase from the 77% reduction announced just two days earlier. Under the latest update, JAL will cut a total of 4,366 flights during April. Flight reductions will now apply on all 60 of its international routes.

Among the markets most affected, JAL will operate just 1% of its planned China flights, 3% of Hawaii/Guam services, 4% of its Australasia flights, and 7% of its Korean schedule.

ANA also announced new route cuts Apr. 1, saying it will suspend 3,983 international flights on 72 routes during the Mar. 29-Apr. 24 period, out of a previously planned total of 4,653. This represents a cut of just over 85%, slightly more than in its last update.

Among ANA’s latest changes are reductions on routes to Hanoi, Ho Chi Minh City, San Francisco, New York and Frankfurt.
