Incheon International Airport
Incheon International Airport
Incheon International Airport Korean: ??????, romanized: incheongukjegonghang (IATA: ICN, ICAO: RKSI) is the main international airport serving Seoul, the capital of South Korea. It is one of the largest and busiest airports in the world. This airport opened for business on 29 March 2001, to replace the older Gimpo International Airport, which now serves mostly domestic destinations and shuttle flights to several East Asian metropolitan areas, particularly Shanghai–Hongqiao, Taipei–Songshan and Tokyo–Haneda. Incheon International Airport is located west of Incheon's city center, on an artificially created piece of land between Yeongjong and Yongyu Islands. A shallow sea originally separated the two islands. That area between the two islands was reclaimed for the construction project, effectively connecting the once-separate Yeongjong and Yongyu islands. The reclaimed area and the two islands are all part of Yeongjong-gu, an administrative district of Incheon. The airport has 111 boarding gates altogether, with 44 in Terminal 1, 30 in Concourse A (connected to Terminal 1), and 37 in Terminal 2. This airport was constructed to share the demand for air transport in the 21st century and to serve as a hub airport in Northeast Asia.

History
International air traffic to South Korea increased after the 1988 Summer Olympics. In the 1990s, it became apparent that Gimpo International Airport could not cope with the increased air traffic. The government decided to build a new international airport to reduce the load on Gimpo International Airport.
In November 1992, the construction of the Incheon airport began on reclaimed land between Yeongjong Island and Youngyu Island. It took eight years to finish, with an additional six months for testing. Completion was initially scheduled for 1997 but delayed due to the Asian economic crisis. The airport was officially opened on 21 March 2001.
On 15 November 2006, an Airbus A380 landed at the airport as part of the first leg of its certification trip. Tests on the runways, taxiways, and ramps showed that the airport is fully capable of handling the A380.
To further upgrade service, Incheon and a major Korean logistics firm Hanjin Group (parent company of Korean Air) agreed on 10 January 2008, to build Yeongjong Medical Centre, which was completed in 2012. This hospital serves nearby residents and some 30,000 medical tourists who come to Korea annually.
