Incheon International Airport Expansion Plan

This time I investigated about the expansion plan of Incheon International Airport. So I explain about this expansion plan.

Incheon International Airport is the largest airport in South Korea. It is the primary airport serving the Seoul Capital Area and one of the largest and busiest airports in the world. Since 2005, it has been rated the best airport worldwide by Airports Council International every year. It is also rated as the world’s cleanest airport and the world’s best international transit airport by Skytrax.

The airport opened for business on 29 March 2001 to replace the older Gimpo International Airport, which now serves mostly domestic destinations and shuttle flights to several East Asian metropolitan areas including Beijing, Osaka, Shanghai, Vladivostok, Taipei and Tokyo.

Incheon International Airport is located west of Incheon’s city center, on an artificially created piece of land between Yeongjong and Yongyu Islands. The two islands were originally separated by shallow sea. That area between the two islands was reclaimed for the construction project, effectively connecting the once separate Yeongjong and Yongyu islands. The reclaimed area as well as the two islands are all part of Jung-gu, an administrative district of Incheon.

Incheon International Airport’s terminal has 111 boarding gates altogether, with 44 in Terminal 1, 30 in Concourse A , and 37 in Terminal 2.


 A fourth construction phase the airport is scheduled to be completed in 2024.
