Main Articles: Incheon International Airport and Gimpo Airport
There are two airports that serve Seoul. Gimpo International Airport, formerly in Gimpo but annexed to Seoul in 1963, was the only airport for Seoul from its original construction during the Korean War. Multiple airports were built in and around Seoul immediately before, during, and after the war. The most famous was on Yeouido, which once served as the country’s gateway to the world.
Upon opening in March 2001, Incheon International Airport on Yeongjong island in Incheon changed the role of Gimpo Airport significantly. Incheon is now responsible for almost all international flights and some domestic flights, while Gimpo serves only domestic flights with the exception of flights to Haneda Airport in Tokyo. This has led to a significant drop in flights from Gimpo Airport.
Meanwhile, Incheon International Airport has become, along with Hong Kong and Singapore, a major transportation centre for East Asia. The 2005 AETRA passenger survey, jointly administered by the IATA and Airports Council International, voted it the best airport in the world. It was named by Skytrax as the world's 5th best airport for 2006.
Incheon and Gimpo are linked to Seoul by highways, and Gimpo is also linked by subway (line #5). The Incheon International Airport Railroad, a rail line connecting Incheon Airport to Gimpo Airport opened in March 2007, but the line to Seoul Station in central Seoul will take at least a year more to open. Shuttle buses transfer passengers between Incheon and Gimpo airports.
