Singapore’s Changi is often lauded as the world’s best airport – and it’s also one of the busiest.

Travel intelligence company OAG has released its annual listing of the world’s busiest international flight routes, and three of the top 10 involve going to Singapore: connecting with Bangkok (in eighth place), Jakarta (landing in seventh) and Kuala Lumpur (the very top of the list).

This data is based purely on the number of seats sold on flights throughout 2023. The busiest route, from Malaysia’s capital to Singapore, had 4.9 million total seats purchased. The flight, which lasts just over one hour, is popular with commuters who prefer to travel between the two neighboring countries by air, rather than by car.

All but one of the top 10 busiest routes are in Asia and the Middle East, with the lone exception being the New York-London hop across the pond. OAG notes that the JFK to Heathrow trip was the only flight route in the top 10 whose total capacity went up from 2019.
