The major international gateways to South Korea are Incheon International Airport, Jeju International Airport, Muan International Airport , and Gimhae International Airport in Busan.

Incheon Internatinal Airport, which was named the world's best international airport in 2009, is the main hub for Korean Air, Aisiana Airlines, and Polar Air Cargo. Its 22-story tall control tower is lit 24 hours a day and is the third largest in the world. IIA connects to Seoul via the airport expressway. It features a suspension bridge which is the only way to the airport. Like all first-rate airports, IIA has restaurants, snack bars, foreign exchange, and over 40 duty-free shops.

Busan International Airport is 22 kilometers west of its namesake city and is South Korea's second largest airport. BIS primarily serves flights to the southern region of the country. The airport links with major routes via the Gyengbu Expressway. BIA was an airfield back in the 1950s, but by the next decade the number of flights increased significantly and the name was changed to Busan International Airport. BIA's terminals feature first-rate convenience services, including duty free stores and a food court. Western and Asian fare, as well as authentic Korean dishes, are served in the terminal restaurants. BIA is currently undergoing major reconstruction to expand its services to more locations, including Beijing, Hong Kong, Tokyo, and Southeast Asia.
