British consultancy OAG has published data on the world’s busiest routes in 2024, which are based on seat availability between January and December 2024.

The route between Seoul (Gimpo) and Jeju Island, both in South Korea, was the busiest route in the world, with 14.1 million passengers between the two airports.

Despite being significant, the number is 19% lower than in 2019, before the SARS-COVID-19 pandemic.

Asia stands out with nine of the ten busiest domestic routes in the world, due to the dynamism of the Asian economy and large population.
