These Were Officially The World’s Busiest Flight Routes In 2025, Canada Reviews

At the end of each calendar year, along with Spotify Wrapped and insight into how many minutes you spent on a lime bike, we get the chance to see which of the world’s flight paths were traversed more than any others.

How? Well, thanks to flight data and statistics company OAG, of course. It produces an annual list of the planet’s most-flown flight paths based on Global Airline Schedules Data from January to December, and the results for 2025 have just landed.

It seems that this year, nine out of the top 10 are located in just one region – Asia Pacific – and the path that saw more seats filled than any other (around 14.3 million, to be specific) was in South Korea between Jeju International and Seoul Gimpo airports.

While this number is still 17 percent behind pre-pandemic numbers from back in 2019, the route did see an increase of 1 percent compared to 2024.

In second place is the flight path in Japan between Sapporo New Chitose and Tokyo Haneda (with 12 million seats), and in third place is the route from the same Tokyo airport to Fukuoka (which saw 11.4 million seats sold).

In fifth place was the one entry from outside the Asia Pacific region: Jeddah to Riyadh saw 9.8 million seats sold, which is a staggering 22 percent increase compared to 2019 (the biggest jump in the top 10). Scroll on for a look at the top 10 global list.
