South Korea’s Incheon airport has become the world’s busiest airport for international passengers, in part owing to disruption in the Middle East caused by the Iran war
The airport, South Korea’s main gateway, about 30 miles (48km) west of Seoul, handled 38.39 million international passengers in the first half of 2026, according to preliminary figures compiled by the Airports Council International (ACI), the global trade body for airports
Heathrow in the UK was second, with 37.79 million, followed by Changi airport in Singapore with 34.53 million
It is the first time Incheon has topped the international passenger rankings since opening in 2001. The airport was 10th in the world in 2002, rising to fifth in 2018 and third in 2024 and 2025
Part of the increase was attributed to disruption caused by the US-Iran conflict, which weakened the role of Middle Eastern hubs such as Dubai and diverted some transfer traffic to alternative routes through east Asia, Incheon International Airport Corporation (IIAC) was quoted as saying by the Yonhap news agency

A four-phase expansion completed in late 2024 increased the airport’s annual capacity to 106 million passengers
