Singapore's Changi Airport returned to the top spot in Skytrax's annual list of the world's best airports.

Skytrax, an airline and airport review and ranking site, compiles the list by interviewing travelers from around the world and asking them to rate the entire airport experience – from check-in to departures and beyond.

Skytrax told CNN that this airport "offers something for everyone." Some of its special features include a 40-meter-high waterfall, a butterfly garden, IMAX cinemas, not to mention 280 wholesale and retail stores.

Singapore Changi is primarily a transit airport and judging by traveler reviews, the airport offers a wide range of amenities for all types of customers.
