Air Busan will suspend its flights from Gimhae International Airport to Guam from the first of next month.
The flights, which resumed in November, are being suspended due to a lack of passengers due to the Omicron breakout.
According to the Korea Airports Corporation, the seat occupancy on the once-a-week flight was 6%.
Jeju Air also suspended its flights from Gimhae to Saipan on the 19th due to a similar situation.
The sharp drop in reservations is attributed to the 10-day quarantine measures upon returning to Korea.
