The air route linking Singapore and the Malaysian capital Kuala Lumpur has become the busiest in the world, research shows.
Planes made 30,537 trips between the two airports in the year to February 2018, OAG Aviation said.
The route overtook Hong Kong-Taipei in a list dominated by Asian destinations.
Flying between Singapore and Kuala Lumpur takes about an hour, and there are plans to build a high-speed rail link between the two.
