Incheon International Airport

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.

The new airport was originally planned to be located in Cheongju, 124 km southeast of Seoul, but due to its distance, it was opposed by Seoul and Gyeonggi citizens. Hwaseong, the other choice, was also rejected due to similar reasons. Finally, the area chosen was Incheon.

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.

Operations

The airport opened for business in early 2001 to replace the older Gimpo International Airport, which now serves mostly domestic destinations plus shuttle flights to Beijing–Capital, Kaohsiung, Nagoya–Centrair, Osaka–Kansai, Shanghai–Hongqiao, Taipei–Songshan and Tokyo–Haneda although flights to Beijing, Kaohsiung, Nagoya and Osaka also operate from Incheon Airport.

Located 48 km west of Seoul, the capital and the largest city of South Korea, Incheon International Airport is the main hub for Korean Air, Asiana Airlines, Jeju Air, and Polar Air Cargo. The airport is a hub for international civilian air transportation and cargo traffic in East Asia. In 2024, the Incheon International Airport was the sixth-busiest airport in the world and third in Asia by cargo traffic, and 13th in the world and seventh in Asia by passenger traffic.

In 2016, the airport served a total of 57,849,814 passengers.

Construction phases

The airport was originally planned to be built in three phases, incrementally increasing airport capacity as the demand grew. This was changed, however, to four phases after the airport was opened.

Phase 1

In Phase 1, the airport had a capacity of 30 million passengers annually, and a cargo capacity of 2,700,000 tonnes annually. In this phase, a passenger terminal with a floor space of 496000 m2, two parallel runways, a control tower, an administrative building, a transportation centre (the Integrated Transportation Centre, designed by Terry Farrell and Partners and Samoo Architects & Engineers), an integrated operations centre, three cargo terminals, international business centre, and a government office building were constructed.

Phase 2

Phase 2 construction began in 2002 and was originally expected to be completed in December 2008. However, in an attempt to have the airport ready for the 2008 Beijing Olympics, which took place in August 2008, the schedule was modified, and Phase 2 construction was completed on 20 June 2008. During this construction phase, a third parallel 4000 m runway and a 13 hectare cargo terminal area was added. A 16.5 hectare concourse connected to the main passenger building via two parallel 870 m underground passageways were added, with a Mitsubishi Crystal Mover shuttle train APM shuttling passengers between the concourse and the main terminal.

Many long-distance foreign carriers were moved to the new concourse, with Korean Air and Asiana Airlines continuing to use the existing terminal.

Phase 3

The South Korean government invested ₩4 trillion until 2017 to expand Incheon International Airport. The second passenger terminal was constructed in the northern field of the airport, and its existing cargo terminal and other infrastructures were expanded. The terminals are connected by the underground "Starline" train. Also, a Landside Connecting system (Bus shuttle) is used for airport employees and departing passengers who don't come to the right terminal. After completion, Incheon International Airport can handle 62 million passengers and 5800000 t of cargo a year, up from the previous capacity of 44 million passengers and 4500000 t. Construction began in 2011 and was completed in 2017. The terminal opened on 18 January 2018. Incheon's expansion also includes adding more aprons to park planes and extending a railway line to the city center of Seoul about 70 km away from the airport. The airport also signed an agreement to build a resort called "Inspire" which includes 6-star hotels, theme parks, and a casino.

Phase 4

Between 2017 and 2024, a fourth construction phase at the airport was taking place. There was an expansion of Terminal 2, the building of a fourth runway and additional apron and car parking facilities. Following completion of the works, it is expected that the hourly flight capacity of the airport will increase from 90 to 107. The 4th runway opened first on 17 June 2017 and phase 4 construction fully completed later on 3 December 2024.

There are long-term plans for a fifth runway and a third terminal to handle low-cost carriers.

Terminals

Terminal 1

Terminal 1 (measuring 496000 m2) is the largest airport terminal by area in South Korea. Terminal 1 was designed by Curtis W. Fentress, FAIA, RIBA of Fentress Architects. It is 1060 m long, 149 m wide, and 33 m high. Its construction cost was 5.632 trillion South Korean Won. The terminal has 47 boarding ports (all of which can accommodate the Airbus A380), 50 customs inspection ports, 2 biological quarantine counters, 6 stationary and 14 portable passenger quarantine counters, 120 arrival passport inspection counters, 8 arrival security ports, 28 departure security ports, 252 check-in counters, and 120 departure passport inspection counters. In 2015, an automatic check-in counter lane was introduced, which people travelling via Korean Air, Asiana Airlines and China Southern Airlines can use. Instead of having airport staff at the counter, there is a machine where travellers input their flight information, scan their passports, receive their flight tickets and lastly, load the luggage onto the conveyor. This system was planned to be introduced in Terminal 2, but in May 2015, Incheon Airport used one of the counter islands for the unmanned luggage handling system.

In December 2023, a Oneworld-branded and operated lounge opened in Incheon Airport Terminal 1 to serve passengers flying on seven of the alliance's 15 member carriers who serve the airport: American Airlines, Cathay Pacific, Finnair, Malaysia Airlines, Qantas, Qatar Airways, and SriLankan Airlines. It is the first in a series of planned lounges under development by the alliance.

Midfield Concourse

The passenger concourse was completed at the end of May 2008. It is connected to Terminal 1 by two parallel 870 m underground passageways equipped with IATs (Intra Airport Transit). It has 32 gates and six lounges.

Terminal 2

A new passenger terminal, designed by Gensler, opened on 18 January 2018, and Korean Air, Air France, Delta Air Lines, and KLM flights were relocated from Terminal 1 to Terminal 2. Other SkyTeam members such as Aeroflot, Aeroméxico, China Airlines, Garuda Indonesia, and XiamenAir started serving Terminal 2 on 28 October 2018. From 1 July 2023, Jin Air, the low-cost subsidiary of Korean Air, started operating at Terminal 2. And the rest of the SkyTeam members, such as China Eastern Airlines, Shanghai Airlines, and Vietnam Airlines will be relocated to Terminal 2 later in the future. From 29 July 2025, Air Busan started operations at Terminal 2, followed by Air Seoul (from 9 September 2025) and Asiana Airlines (from 14 January 2026) relocated to Terminal 2 as well due to the merger with Korean Air. From 13 September 2025, Scandinavian Airlines started an inaugural flight to Incheon, using Terminal 2. From March 2026, Virgin Atlantic will start flying into Incheon using Terminal 2 as well.

The airport area also has a golf course, spa, private sleeping rooms, an ice skating rink, a casino, indoor gardens, a video game center and the Museum of Korean Culture.

Accidents and incidents

• On 16 June 2011, an Airbus A321-200, operating as Asiana Airlines Flight 324 between Chengdu Shuangliu International Airport, China and Incheon International Airport, was fired upon by two soldiers of the Republic of Korea Marine Corps as it came in to land at Incheon. A total of 99 rounds were discharged at the aircraft, which was out of range and it made a safe landing without sustaining any damage. The soldiers had misidentified the aircraft as belonging to the North Korean military and were acting on orders that permitted them to engage without reference to senior officers, following the Bombardment of Yeonpyeong in November 2010.

Ground transport

Public transport

Rail

The Airport Railroad Express (AREX and styled as A'REX) has two stations located in both the Transport Centre adjacent to the Terminal 1 building (Incheon International Airport Terminal 1 station) and is in the basement of Terminal 2 (Incheon International Airport Terminal 2 station). It provides service to Gimpo International Airport and Seoul. Many of the stations along the line provide connections to Incheon Subway, Seoul Metropolitan Subway, and Incheon Airport Maglev.

For departing passengers, Seoul Station City Airport Terminal offers in-town early check-in service and has related immigration services before arriving at the airport. Seoul Station City Airport Terminal is the only available place in Seoul where in-town check-in service is provided. That is since CALT closed its in-town check-in operation at Gangnam in 2023.

The Korea Train eXpress (KTX) operated at the same station as AREX but used a different platform. It operated 20 times per day from the airport; twelve times on the Gyeongbu Line, twice on the Gyeonjeon Line, four times on the Honam Line, and twice on the Jeolla Line. The service started in 2014 but was suspended in March 2018 due to low ridership. The suspension became permanent in September 2018 as the line was officially closed.

The Incheon Airport Maglev opened on 3 February 2016 and closed on 1 September 2023. The first phase was to be 6.1 km long, spread over six stations (but eight stations were built, spanning more than 8 km), taking riders from the airport toward the southwest of the island where a water park is located. Phase 2 was to be 9.7 km long, extending the line to the northwest of the island. Phase 3 would have added 37.4 km, transforming the line into a circle. After converting the tracks from Maglev to orbital tram tracks, service is expected to resume from March 2024.

Bus

Airport shuttle buses transport passengers between Terminal 1 and Terminal 2. Buses are free, arrive every 5 to 8 minutes, take approximately 20 minutes of travel time, and stop at the Hyatt Hotel or airport fire station en route, depending on direction. Airport buses are called limousine buses. Standard limousine buses travel to Gimpo Airport & Songjeong station. Intercity buses connect with other towns and cities in Korea. The City Air Logistics & Transportation company runs an airport bus line directly connected to the bus station at COEX, Gangnam.

Ferry

A ferry service connects Yeongjong-do to the mainland. However, the dock is located a considerable distance from the airport. An alternative means of transport must be sought upon arriving at the island to be able to get to the airport.

Car

The airport provides a short-term parking lot for 4,000 cars and a long-term parking lot for 6,000 cars. Shuttle services connect the long-term parking lot to the passenger terminal and the cargo terminal. Car rental is located near the long-term parking lot. A link to the mainland is provided by the toll Yeongjong Bridge and an expressway. A second expressway on the Incheon Bridge also connects the island to central Incheon.

Roads

It is connected to the Incheon Bridge and the 2nd Gyeongin Expressway. Airport limousine buses, which have been operating since the day Incheon International Airport opened, and many visitors in private cars use this road. When the 3rd Yeonyukgyo Bridge opens in 2025, a general road connecting to the Gyeongin Expressway, Incheon Airport will be accessible by two-wheeled vehicles and on foot.

Traffic and statistics

In 2017, the airport was the world's fourth busiest airport by cargo traffic and third in Asia, and the world's 19th busiest airport by passenger traffic and ninth in Asia. In 2019, the airport served a total of 70,857,908 passengers.

Top destinations

As a general rule, Hong Kong is strictly separated from Macau because of historical reasons. However, the distance between the two cities is very short and also economical, cultural exchanges are so active. Thus, this table ties together for convenience.

Annual traffic

After COVID-19 ended, it recovered dramatically. In about nine months, the number of passengers increased to the level of the previous year.

Marketing

In August 2025, singer-actress IU was named promotional envoy for Incheon Airport customs. In September 2025, the Incheon International Airport Corporation (IIAC) announced that they have appointed actor Park Bo-gum as honorary ambassador. On Park's three-year honorary ambassadorship, the IIAC's president Lee Hak-jae said, "By appointing actor Park Bo-gum, a representative 'story maker' in the entertainment industry who possesses acting skills, star quality, and character, as an honorary ambassador, we expect that this will enhance Incheon Airport's brand value both domestically and internationally and further activate communication with the public."

In popular culture

The Sims 4 team released The Sims 4: Incheon Arrivals kit, inspired by the fashion at the Incheon airport.

Scenes in seasons 1 and 2 of Squid Game were filmed in Incheon International Airport. During the filming of the season 2 scenes, there was alleged mistreatment towards members of the public from the production staff, causing the production company to release an apology.

Accolades

As of 2024, the airport has been rated by Skytrax as the third-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.

Its duty-free shopping mall has been rated the world's best for three years in a row in 2013 by Business Traveller.
