What is the busiest airport route in the world?

KEY POINTS
  • The busiest international airline route in November 2023 is Hong Kong (HKG) to Taipei (TPE) with 525,628 seats. ...
  • Cairo (CAI) to Jeddah (JED) is the second busiest international route with 410,584 seats.




As of 2026, the undisputed busiest air route in the world remains the short hop between Jeju International (CJU) and Seoul Gimpo (GMP) in South Korea. This domestic corridor consistently handles over 14 million seats annually, driven by the immense popularity of Jeju Island as a vacation destination for mainland Koreans. Following closely in the global rankings are other Asian domestic routes, specifically Sapporo New Chitose to Tokyo Haneda in Japan and Hanoi to Ho Chi Minh City in Vietnam. In the international category, the route between Cairo and Jeddah has recently surged to the top spot, reflecting massive travel demand for religious pilgrimage and business between Egypt and Saudi Arabia. These rankings highlight that while long-haul transoceanic flights get the most attention, high-frequency "commuter" style routes in Asia and the Middle East move the largest volumes of passengers globally.
