For the fourth year in a row, Singapore Changi Airport been named the best airport in the world for raising the bar on passenger experiences.

In the 2016 edition of the World Airport Awards, Singapore Changi managed to keep a firm grasp on its crown thanks to features like tropical rooftop gardens, movie theaters, free foot massages, video gaming areas, and free sightseeing tours into the city for flyers.

Like previous years, the top 10 airports hail mostly from Asia and Europe, with Japan alone landing three airports on the ranking.

The list is also conspicuously absent of any North American hubs which could learn a lesson or two from airports like Changi which turn what can be a stressful place of transit into a destination in and of itself.

For instance, specs for the newest addition to the hub, Jewel Changi Airport, will boast everything from an indoor forest, walking trails and gardens to a 40-meter tall Rain Vortex which will be the world's tallest indoor waterfall when complete.

The glass biodome complex is expected to be complete in 2018.

The World Airport Awards are based on the results of 13 million surveys completed by flyers from 112 nationalities who rate their satisfaction levels across 39 indicators from check-in to departure.

The ranking included 550 airports for consideration.

Here are the world's top 10 airports 2016:
