Incheon International Airport

Incheon International Airport (IATA: ICN, ICAO: RKSI) is the main international airport serving Seoul, the capital of South Korea. It is also one of the largest and busiest airports in the world.

As of 2021, the airport has been rated by Skytrax as the fourth-best airport in the world. Skytrax has also rated the airport as the world's best international transit airport and one of the world's cleanest airports. The airport is one of Skytrax's 5-star airports and has also been awarded for the best airport security in 2021.

During the entire run of the best airport worldwide ranking by Airports Council International (ACI) from 2005 to 2011, Incheon International Airport topped the ranking every year. ACI also rated the airport as the best airport in Asia-Pacific for 10 consecutive years from 2006 to 2016 until the ranking series ended in 2017. The airport has been ranked first place in the services field, regardless of the COVID-19 term. Incheon International Airport Corporation declared 'COVID-19 Free Airport.' It took the lead in quarantine against the spread of coronavirus. Also, the airport tried to prevent the collapse of the aviation industry during COVID-19. At the same time, despite the huge deficit, a policy of rent reduction and mooring usage fee exemption was implemented to ensure employment stability for 70,000 airport workers.

This airport has a golf course, spa, private sleeping rooms, an ice skating rink, a casino, indoor gardens, video game center and the Museum of Korean Culture. The airport's average departure and arrival take 19 minutes and 12 minutes respectively, compared to a worldwide average of 60 minutes and 45 minutes, ranking it among the fastest airports in the world for customs processing. Its duty-free shopping mall has been rated the world's best for three years in a row in 2013 by Business Traveller. Incheon International Airport also reports a 0.0001% baggage mishandling rate.

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, including Beijing–Capital, Osaka–Kansai, 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 as well as the two islands are all part of Jung-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.
