Incheon International Airport has surpassed 1 billion cumulative passengers in 25 years and three months since it opened, achieving the milestone faster than major competing hub airports including Germany's Munich Airport, Singapore's Changi Airport and Japan's Narita Airport.
Incheon International Airport Corporation said Monday that the airport reached 1 billion cumulative passengers in 25 years and three months, or 9,232 days in total, since it opened on March 29, 2001. That works out to an average of 108,000 passengers a day, 4,513 an hour and 75 a minute using Incheon Airport.
Based on the world's population of 8.3 billion, it means one in eight people has used the airport, or about 19 times per South Korean citizen.
This is the fastest record among major global hub airports competing with Incheon. Reaching 1 billion cumulative passengers took Munich Airport 33 years and 10 months, Changi Airport 35 years and five months, Narita Airport 39 years and two months, and Dubai Airport in the United Arab Emirates (UAE) 58 years and two months.
The airport corporation held a ceremony marking the 1 billion cumulative passenger milestone at the Great Hall on the first floor of Incheon Airport's Terminal 2 in the afternoon. The 1 billionth passenger was Ayaka Hara, a Japanese national departing for Tokyo, Japan on Korean Air flight KE713, and the corporation presented her with a commemorative plaque and an air ticket.
Since opening, Incheon Airport reached 100 million cumulative passengers in October 2005 and surpassed 500 million in July 2016. It then added another 500 million over the following decade, even through the COVID-19 pandemic, to reach 1 billion cumulative passengers.
By country, cumulative passengers on routes to Japan were the largest at 204.79 million. Japan was followed by China with 185.37 million, the United States with 86.1 million, Vietnam with 67.07 million and Thailand with 59.25 million. By city, the Incheon-Narita route ranked first with 60.74 million, followed by Hong Kong, Kansai, Bangkok and Taipei.
By airline, Korean Air had the most passengers at 309.15 million. Asiana Airlines followed with 208.11 million, Jeju Air with 48.31 million, Jin Air with 37.96 million and T'way Air with 27.77 million.
Last year, Incheon Airport handled 74,071,475 international passengers and 2,954,684 tons of international cargo, rising to the world's third-largest airport under Airports Council International (ACI) standards. Transfer passengers also reached 8,046,572, establishing it as a leading hub airport in Northeast Asia.
Its aviation network has also expanded. Currently, 101 airlines connect 183 cities in 53 countries, and its 31 routes to Japan serve more destinations than Narita Airport and Kansai Airport. In air cargo, the airport handles 99% of semiconductor exports, serving as a gateway for the national economy.
Infrastructure has also steadily expanded. Incheon Airport completed its Phase 4 construction project in November 2024, giving it the world's third-largest international terminal infrastructure, capable of handling 106 million passengers a year. A total of 18.017 trillion won was invested in the Phase 1 through Phase 4 expansion works, of which 82% was self-funded through means such as issuing corporate bonds.
Drawing on the construction and operational know-how accumulated since it opened, the corporation is also expanding its overseas business. It has so far won 42 overseas projects in 18 countries worldwide, with cumulative orders reaching $585.58 million.
The construction and operation of Incheon Airport is currently regarded as a leading role model for successful state projects in the global airport industry.
The airport corporation plans to step up efforts to strengthen connectivity between Incheon Airport and major domestic regions, enhancing the convenience of overseas travel for citizens and actively supporting the government's goal of attracting 30 million foreign tourists.
"I would like to thank the government's support, the public's encouragement and the hard work of resident employees for Incheon Airport's growth into a world-class airport used by 1 billion passengers worldwide," said Kim Beom-ho, acting president of Incheon International Airport Corporation. "We will continue to enhance public convenience through ongoing facility investment and service innovation, and contribute to the development of the national aviation industry."
