The Ministry of Land, Infrastructure, and Transport will investigate air traffic demands at Jeju airport in June of this year. The investigation will include a base benchmark that is then measured against the differentiated demands of each airport in the nation. The project will decide whether to expand existing airport facilities or construct a new airport in preparation for increased numbers of tourists.

Jeju is in the running to be selected for new airport construction as reflected in the fifth airport development long-term plan to be reviewed at the end of 2015.

The Ministry of Land, Infrastructure, and Transport forecasts that Jeju International Airport will become overcrowded, and is expected to peak in 2019, six years earlier than previous estimates.

President Park Geun-hye pledged to expand Jeju International Airport or construct a new facility during her presidential campaign last year. In addition, at the Supreme Council held in Jeju in February, the ruling Saenuri Party stated the project was a top priority.
