Jeju International Airport
Jeju International Airport is the 2nd largest airport in South Korea, just behind Incheon Airport in Incheon. It is located in the city of Jeju. The airport opened in 1968.
Jeju International Airport serves many mainland destinations in South Korea, as well as international destinations in China, Hong Kong, Japan, Taiwan, Thailand and Malaysia. In 2015, 26,237,562 passengers used the airport. It is home to the world's busiest airline route, to Seoul-Gimpo.
Due to the large number of passengers using the airport and its limited capacity it was announced that a second airport would be constructed on the island near the southern city of Seogwipo with an investment of 3.8billion USD. It is expected to open to the public in 2025.Airlines and destinations
