As international oil prices have surged due to the war between the United States and Iran, domestic airlines with worsening profitability are successively cutting flight routes.

According to the aviation industry on the 1st, Jeju Air, a low-cost carrier (LCC), decided to cut a total of 110 flights on three routes operating between Incheon and Hanoi, Bangkok and Singapore from next month through June. This is the largest reduction plan announced so far by domestic airlines.

Specifically, from the 12th of next month to June 30, the Incheon–Hanoi route will be reduced from seven times a week to four, for a total reduction of 44 flights. From the 8th of next month to June 30, the Incheon–Bangkok route will be reduced from seven times a week to four, for a total of 48 flights, and from the 8th to the 26th of the same month, the Incheon–Singapore route will be reduced from seven times a week to four, for a total of 18 flights, respectively.

Jeju Air is said to be planning to offer alternative flights to customers who booked flights that are already scheduled not to operate.

As jet fuel prices rise due to the war between the United States and Iran and the possibility grows that passenger demand on international routes will decline, airlines have recently been announcing a series of flight reduction plans.

Asiana Airlines, which entered emergency management on the 25th of last month, decided to cut a total of 14 round trips on four international routes, including China and Cambodia, through next month.

Jin Air decided to reduce 45 round-trip flights this month on a total of eight routes, including routes between Incheon and Guam and Nha Trang, and routes between Busan and Cebu. AIR SEOUL will also reduce flights on the Incheon–Guam route this month.

In addition, Aero K will reduce flights from this month through June on four routes including Cheongju–Ibaraki, Narita, Clark and Ulaanbaatar; AIR BUSAN will reduce flights this month on three routes including Busan–Da Nang, Cebu and Guam; and Air Premia will reduce flights from this month through next month on Incheon–Honolulu and Los Angeles (LA), and next month on Incheon–Washington and Bangkok, for a total of four routes.
