Incheon International Airport's terminal has 111 boarding gates altogether, with 44 in Terminal 1, 30 in Concourse A (connected to terminal 1), and 37 in Terminal 2. The airport holds a record of being ranked the Best Airport Worldwide for 11 consecutive years by the Airports Council International (ACI)'s Airport Service Quality Award from 2005 to 2016, and has also been rated the world's best among airports of its size (25–40 million passengers) and region (Asia-Pacific) since 2012 due to the institution's decision to discontinue the Best Airport Worldwide category. The reclaimed area as well as the two islands are all part of Jung-gu, an administrative district of Incheon. That area between the two islands was reclaimed for the construction project, effectively connecting the once separate Yeongjong and Yongyu islands. The two islands were originally separated by shallow sea. Incheon International Airport is located west of Incheon's city center, on an artificially created piece of land between Yeongjong and Yongyu Islands.


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 Tokyo, Osaka, Beijing, Shanghai, and Taipei. It is also rated as the world's cleanest airport and the world's best international transit airport by Skytrax. Since 2005, it has been rated the best airport worldwide by Airports Council International every year. Incheon International Airport (IIA) (IATA: ICN, ICAO: RKSI) (sometimes referred to as Seoul–Incheon International Airport) is the largest airport in South Korea, the primary airport serving the Seoul Capital Area, and one of the largest and busiest airports in the world.
