Singapore Changi has been voted the world's best airport by Skytrax more than a dozen times, and it earns it with things most airports do not attempt: a butterfly garden, a rooftop swimming pool, free cinemas and a slide that drops through several floors of a terminal. The current schedule feed lists 178 airports in 50 countries connected to Singapore.
Its Jewel complex, open to the public as well as travelers, is built around the Rain Vortex — the tallest indoor waterfall in the world — ringed by an indoor forest. Changi is the hub of Singapore Airlines and Southeast Asia's principal connecting point.
