Seoul Incheon International is one of two airports serving the Korean capital – the other being Gimpo International – and it's the busiest of all airports in South Korea.
Incheon is split into two areas – Terminal 1 (or Main Terminal) and Concourse, with a third under construction. The Main Terminal handles flights from local carriers such as Korean Air and Air Seoul, while foreign airlines use the Concourse.
Terminal 2 is scheduled to be opened in 2018, and will handle flights for Korean Air and members of the SkyTeam.
As well as the usual array of shops and restaurants, Incheon Airport has a Museum of Korean Culture, an ice skating rink, indoor gardens and a golf course to help you pass the time.
For those stopping over in Incheon with a wait of more than eight hours, it's possible to book a tour to the DMZ (Demilitarized Zone) that stands between North and South Korea. Some free tours are available from the arrival hall for people with shorter transit times.
