SINGAPORE — A one-hour flight linking Singapore with Kuala Lumpur is the world’s busiest international route.

Planes made 30,537 trips between the island-state and the Malaysian capital in the 12 months to February, according to a report by OAG Aviation Worldwide Ltd. That is the equivalent of 84 flights a day in one of the world's smallest countries with a population of just 5.6 million.

In a top-20 list dominated by Asia, the highest-ranking route outside the region ran between New York and Toronto. There were 16,956 flights on that leg. The trip between Dublin and London Heathrow ranked 14th and was the busiest European entry with 14,390 flights.

In terms of passenger numbers, Hong Kong-Taipei tops the list with 6.5 million people flying that route in the 12-month period, the report showed. That is followed by Jakarta-Singapore with 4.7 million and Kuala Lumpur-Singapore with 4 million.

Asia is the world’s fastest-growing travel market. But even the most frantic international routes do not come close to the most popular domestic flights.

The world’s busiest air route, bar none, is between Seoul and a tiny island off the coast of South Korea. Planes made 65,000 trips between the South Korean capital and Jeju island in 2017, according to OAG. BLOOMBERG
