Incheon International Airport is the largest international airport in South Korea where all international flights leave and arrive every day. Gimpo Airport located near city Seoul used to be the international airport for Korea. However as the population grew and needs for places to stay increased in the area, Gimpo Airport no longer could expand its capacity to meet the growing demands for international flights. To solve the problem, a construction plan for a new 24 hour airport was started in 1992. Incheon International Airport is in Incheon City Jung-gu Unseo-dong (37°27′5″N, 126°26′4″E). Incheon International Airport Railroad (A'REX) and Incheon International Airport Highway were built to join the airport to Seoul. The airport is operated by Incheon International Airport Corporation (IIAC) and it is owned by the government of South Korea.
