What are the world's best airports?

Yesterday, Skytrax held its annual World Airport Awards ceremony. To determine which airports took out top prizes, millions of air travellers were surveyed in hundreds of destinations.

This year's survey saw a few positions changing, with some perennial favourites being knocked off the perch and other airports moving up dramatically in the rankings.

The top airports by continent were as follows:

And what about Asia? Well, the top Asian airport was also ranked number one worldwide: Singapore's Changi Airport, a sprawling megalopolis that's only part airport (and part shopping mall/entertainment hub).

The overall second- and third-ranked airports were longtime superstars Seoul and Hong Kong. The USA nudged into the top 20 with San Francisco.

And the biggest improver? That title goes to Abu Dhabi, which skyrocketed from 73 last year to 26.

What do you think? Did the survey get the airports right, or are there lesser-known gems that aren't getting the press they deserve? What's your favourite airport?
