It’s no surprise that Changi came out on top again. The international transit hub has incredible amenities, such as a butterfly garden, rooftop pool, movie theatres, hotels, spas, and showers — and even a four-story slide.
Skytrax based its rankings on 12.85 million customer nominations across 110 nationalities and includes 410 airports worldwide. It incorporates passenger satisfaction across nearly 40 categories, including service and shopping and security and immigration.
All the airports commended last year made the 2014 list, but in a slightly different order.

Yearly passengers: 69.4 million
Why it's awesome: Despite London Mayor Boris Johnson's concern that Heathrow gives visitors 'a terrible impression of the U.K.,' the overcrowded airport made it into Skytrax's top 10.
The third-busiest airport in the world in 2011, it took home the awards for Best Airport Shopping and Best Airport Terminal, for T5, which opened in 2008 after a $US6.2 billion, 19-year design and construction process.
