South Korea’s Incheon airport beats Heathrow to become world’s busiest

Incheon International Airport in South Korea has recently claimed the title of the world's busiest airport by international passenger traffic, surpassing London Heathrow Airport. According to preliminary data from the Airports Council International, Incheon served 38.4 million international passengers during the first six months of the year. London Heathrow Airport came in second place with 37.79 million passengers, followed closely by Singapore's Changi Airport, which handled 34.53 million passengers.

Incheon's rise to the top spot can be attributed to several factors, primarily the diversion of passengers from Middle Eastern hubs due to tensions between the U.S. and Iran. Dubai International Airport, which had held the second position in both 2024 and 2025, is anticipated to fall outside the top five this year. Both London Heathrow Airport and Incheon International Airport ranked 12th and 13th, respectively, in the previous year.

The shift in passenger traffic from Dubai to Incheon has resulted in an 18% increase in transfer passengers bound for Europe, with 210,000 travelers now using Incheon as a transit point. The airport corporation attributes this growth to the expansion of its infrastructure, which has enabled it to handle a larger volume of air traffic.

Incheon International Airport, which opened its doors in 2001, serves 158 international destinations, compared to Hong Kong's International Airport (139 destinations), Shanghai's Pudong Airport (92 destinations), and Tokyo's Narita Airport (86 destinations).

The Incheon Airport Corporation's acting president, Kim Beom-ho, expressed gratitude towards the South Korean government, public support, and the dedication of staff members, attributing the airport's achievement to their collective efforts. Kim also emphasized the corporation's commitment to further enhancing the airport's competitiveness by prioritizing passenger convenience.
