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. 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 has a golf course, spa, private sleeping rooms, an ice skating rink, a casino, indoor gardens, video Game Center and a Museum of Korean Culture. Airport authorities claim that average departure and arrival takes 19 minutes and 12 minutes, respectively, as compared to worldwide average of 60 minutes and 45 minutes, respectively, ranking it among the fastest airports in the world for customs processing. Its duty-free shopping mall has been rated the world's best for three years in a row in 2013 by Business Traveller. Incheon International Airport also claims that it has only a 0.0001% baggage mishandling rate.
The airport opened for business on March 29, 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.
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.
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 was constructed to share the demand for air transport in the 21st century and to serve as a hub airport in Northeast Asia.
