Japanese and South Korean carriers have made further reductions to their summer schedules in light of the coronavirus outbreak.

ANA had planned to serve a total of 4,653 flights on 72 routes between March 29 and April 24, but says 3,813 of those, on 68 different routes, have now been affected by reductions or suspensions.

The major changes in an update provided on March 27 are China flights, in line with new Chinese government restrictions on international flights. ANA will now fly only once a week to Shanghai during this time. In India, it will only operate relief flights to Delhi over the next 10 days and says more of such relief flights are under negotiation.

Among the few ANA routes operating as planned are Tokyo Narita to Los Angeles and Chicago. However, new routes from Tokyo Haneda to San Francisco and San Jose have been postponed until April 25.

Japan Airlines said on March 27 it will operate only 28% of its previously planned international flights between March 29 and April 30. It continues to operate 46% of its planned schedule to the Americas, but capacity to Europe is down 73%.

Meanwhile, more than 90% of Korean Air’s aircraft are grounded, Chairman Walter Cho said during the parent group, Hanjin KAL’s annual shareholder meeting on March 26. In China, it is flying only to Shenyang. Many routes to the United States have been reduced, while all European routes have been suspended, apart from London and Paris, which are down to three times a week.

Asiana Airlines is reducing flights to Frankfurt over the next two weeks and London during April, while its Paris service is suspended until Apr 29. US routes affected by cutbacks include Honolulu, New York JFK, Los Angeles, Seattle and San Francisco.
