Bangkok Suvarnabhumi-Singapore came 11th, with 14,859 trips and 2.9 million passengers during the period, followed by Bangkok Suvarnabhumi-Hong Kong, with 14,832 trips and 3.7 million passengers.
The trip between Singapore and the Malaysian capital Kuala Lumpur is the world's busiest global air route, with more than 30,500 flights between the cities in the year to February, a new study showed. This translates to 84 flights a day, the Bloomberg report said.
"The carriers are Air Asia, Malaysia Airlines, SilkAir, Jetstar, Singapore Airlines, Malindo Airways and Scoot".
In terms of passenger numbers, the Singapore-Kuala Lumpur route claimed third place with 4 million passengers carried in the 12-month period, trailing behind Hong Kong-Taipei (6.5 million) and Jakarta-Singapore (4.7 million). This is followed by Jakarta-Singapore with 4.7 million, and then Kuala Lumpur-Singapore with 4 million.
Two operate within Europe, two in North America, one between North America and Europe, while another is in the Middle East, it added.
The Singapore-KL connection topped OAG's busiest worldwide routes rankings with 30,537 flights, compared with 28,887 flights for Hong Kong-Taipei and 23,704 flights for Singapore-Jakarta. All eight of the 10 busiest routes that are located in Asia have at least six competing airlines, compared to routes such as Dublin-London Heathrow and Chicago-Toronto that have only four.
"Given the robust expansion of air passenger travel across Asia Pacific and the fierce competition between carriers in the region, it is unsurprising that 14 of the world's busiest 20 routes, including eight of the top 10 routes, are between Asian city pairs", said Mayur Patel, regional sales director JAPAC for OAG.
