Japan Airlines and All Nippon Airways will significantly scale down their international and domestic flights in the coming business year due to a sharp fall in demand, officials of the two airlines said Tuesday.

JAL will reduce the number of flights on international routes linking Narita International Airport with New York, Bangkok and Seoul. ANA will abolish its flights from Central Japan International Airport in Aichi Prefecture to the major Chinese cities of Guangzhou and Tianjin.

The airlines see slashing flights as necessary, even on international routes bound for key cities in North America and China, amid the deepening global economic slump.

They are expected to announce the downsizing plans later this week.

JAL earlier said that it will terminate its flights between Kansai airport and London.

Both airlines will slash flights between Tokyo's Haneda airport and Kansai airport.
