SINGAPORE - Changi Airport has been named the world's best airport for the seventh straight year.

In the global survey by London-based research firm Skytrax involving more than 13 million travellers, the Singapore airport was also named the best in Asia and the best in the world for leisure amenities.

Tokyo International Airport (Haneda) came in second, followed by South Korea's Incheon International Airport which took third spot.

Changi Airport has bagged the best airport title 10 times in the 20-year history of the World Airport Awards.

In receiving the award, Changi Airport Group chief executive Lee Seow Hiang said: "This achievement was made possible by the strong support from our airport partners... We thank our passengers for their continued support.
