It began to operate flights on the routes from Incheon International Airport in Seoul on November 21.

The routes were launched amid a drop in Korean people’s demand for travel to Japan due to a trade row between the two countries.

Jeju Air shifted to a net loss of 30.1 billion won (27 million USD) in the third quarter of 2019 from a net profit of 31.1 billion won a year earlier.

It said Korean travellers have increasingly opted not to travel to Japan due to Japan's export curbs, dealing a blow to the quarterly earnings results. The won's weakness against the US dollar also weighed on the bottom line.

The airline operates 45 B737-800s on six domestic routes and 70 international routes, mainly to Singapore and other Southeast Asian countries. VNA
