Incheon International Airport has surpassed 1 billion cumulative passengers, 25 years and three months after it opened. The airport reached 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 25 years and three months after opening on March 29, 2001, a total of 9,232 days. That works out to a daily average of 108,000 passengers, 4,513 per hour and 75 per minute using Incheon Airport.
Based on the world's population of 8.3 billion, that equals one in every eight people, or about 19 uses per South Korean citizen.
This is the fastest record among the world's major hub airports that compete 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 corporation held a ceremony Monday afternoon to mark the 1 billion cumulative passenger milestone at the Great Hall on the first floor of Terminal 2 at Incheon Airport. The 1 billionth passenger was Hara Ayaka, a Japanese national who departed for Tokyo, Japan, on Korean Air flight KE713, and the corporation presented her with a commemorative plaque and airline tickets.
Since opening, Incheon Airport reached 100 million cumulative passengers in October 2005 and passed 500 million in July 2016. It then added another 500 million over the next 10 years, even through the COVID-19 pandemic, to record 1 billion cumulative passengers.
By country, cumulative passengers on Japan routes were the highest at 204.79 million. Next were 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 recorded 74,071,475 international passengers and 2,954,684 tons of international cargo, rising to the world's third-ranked airport by the Airports Council International (ACI) standard. Transfer passengers also reached 8,046,572, establishing it as a leading hub airport in Northeast Asia.
Its air network has also expanded. Currently, 101 airlines connect 183 cities in 53 countries, and its 31 Japan routes serve more regions than Narita Airport and Kansai Airport. In air cargo, it handles 99% of semiconductor exports, serving as a gateway for the national economy.
Infrastructure has also steadily expanded. In November 2024, Incheon Airport completed its Phase 4 construction project, establishing the world's third-largest international infrastructure capable of handling 106 million passengers annually. A total of 18.017 trillion won was invested in the Phase 1 through Phase 4 expansion projects, 82% of which was self-financed through means such as corporate bond issuance.
Based on the construction and operational expertise it has accumulated since opening, the corporation is also expanding its overseas business. To date, it has won 42 overseas projects in 18 countries worldwide, with cumulative orders reaching $585.58 million.
"We are grateful for the government's support, the public's encouragement and the hard work of resident staff in growing Incheon Airport 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 and contribute to the development of the national aviation industry through continuous facility investment and service innovation."
