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.
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 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.
