Why are all flights to South Korea cancelled?

KOREA, South Korea (Reuters) – More than half of flights to the Korean Peninsula are to be canceled, with all flights cancelled in the first three months of this year, according to a survey conducted by Korea Air, which flies to the country by private aircraft.

More than 80 percent of the flights to Korea were cancelled in April, while 55 percent of flights in May and July were cancelled, Korea Air said in a statement on Monday.

Korean Air has said it has a limited supply of fuel, and said it would reduce its fuel consumption by up to 25 percent this year.

Korea Air also said it was increasing the number of domestic flights in April to 12,000 and to 6,500 in June, from 4,000 flights in March and May.

The carrier said it had cut its domestic fuel consumption and increased the number and frequency of domestic routes, which it says is a result of increased demand.

Koreas air transport system operator Koryo Tours said last month that it expects to cut its flights by 60 percent in 2020.

Koryo said it will add new routes to the service in 2019.
