Travel

Obviously, size doesn’t matter. Singapore and Kuala Lumpur make a small geographic impression on the world map, but from March 2017 until February 2018, the two made up the busiest international air route.

According to research by OAG Aviation, 30,537 flights between Kuala Lumpur and Singapore operated in the 12 months, carrying over 4 million passengers. The data also revealed that AirAsia was the most-used carrier and – surprise, surprise – Malaysia Airlines was the least punctual operator (61.4% of flights were delayed) on that rout.

Although the flight duration between Kuala Lumpur and Singapore is merely about an hour, there are plans to add another major travel option by 2020: a high-speed rail linking the two destinations. How this changes flight patterns, if at all, remains to be seen.

Of the top 20 routes, 14 are within Asia – Malaysia’s capital city gets another mention at fifth place in the Jakarta-Kuala Lumpur route. Even though the Hong Kong-Taipei route is second busiest, it boasts the most passengers carried (6.5 million).
