韩国仁川国际机场在2026年上半年国际客运量达3839万人次，首次超越英国伦敦希思罗机场成为全球最繁忙的国际客运机场[1]。这是仁川机场自2001年开放以来首次登顶国际客运排名[1]。伦敦希思罗机场以3779万人次排名第二，新加坡樟宜机场则以3453万人次位列第三[1]。
仁川机场的增长与多方面因素相关。美伊冲突导致中东地区航运枢纽中断，大量转机流量改道经由东亚地区，为仁川机场带来了客流增长[1]。机场在同期实现了6.3%的同比增长率[1]。外国访客占比从2025年全年的35.2%上升至2026年上半年的39.3%，第二季度达到44.4%的历史新高，主要来自中国和日本[1]。
仁川机场目前服务101家航空公司，飞往183个城市，其中包括158个国际客运目的地[1]。机场在2024年末完成的四阶段扩建使其年承载容量增至1.06亿人次[1]。
South Korea's Incheon International Airport has claimed the title of world's busiest airport for international passenger traffic, marking a historic milestone for the facility since its opening in 2001.[1] During the first half of 2026, the airport handled 38.39 million international passengers, a 6.3% increase compared to the same period the previous year, surpassing London's Heathrow Airport, which processed 37.79 million passengers, and Singapore's Changi Airport, which served 34.53 million passengers.[1]
The surge in traffic reflects significant shifts in global aviation patterns driven by geopolitical developments. Analysts attribute the growth partly to disruptions in Middle Eastern aviation hubs caused by tensions between the United States and Iran, which have redirected connecting passenger flows through East Asian gateways.[1] International visitors now account for 39.3% of Incheon's passenger base, up from 35.2% for the full year 2025, with the second quarter reaching a record 44.4% share of foreign travelers, predominantly from China and Japan.[1]
Infrastructure expansion has positioned the airport to capitalize on this demand surge. A four-stage expansion project completed at the end of 2024 increased the airport's annual capacity to 106 million passengers.[1] Incheon currently serves 101 airlines operating flights to 183 cities worldwide, including 158 international passenger destinations.[1]
