Nearly 80,000 departures per year – busiest flight route in the world revealed


It might come as a surprise to hear that the world’s busiest air route worldwide isn’t London to Paris, Los Angeles to San Francisco or Beijing to Shanghai.

It’s actually the 282-mile stretch from Seoul to Jeju, an island popular amongst South Korean holidaymakers.

According to UK-based aviation data monitor OAG 79,460 planes departed between Jeju and Seoul Gimpo between March 2018 and February 2019.

Jeju is the largest island off the Korean peninsula and it is sometimes labeled “the Hawaii of South Korea”. It boasts volcanic landscapes that have been afforded UNESCO World Natural Heritage Site status as well as impressive hiking trails and stunning beaches.

It is so popular among Koreans that there are 200 daily services from Seoul spread between eight different carriers.

Across the globe, the ten busiest air routes are all domestic and the connection between Melbourne and Sydney is the second busiest. During the same period, there were 54,102 departures on the 443-mile route between the two Australian cities. Mumbai to Delhi comes third with 45,188 departures.

The busiest international flight path is from Kuala Lumpur to Singapore with 30,187 departures divided between eight different carriers.
