The airport topped the charts at the Skytrax 2019 awards, which are voted on by passengers from all over the world.
Changi connects passengers to 200 destinations worldwide, with 5,000 arrivals and departures a week on 80 airlines.
The transport hub advertises itself as “More than an airport”: attractions include art installations and sculptures, a butterfly park, cactus garden and cinema.
Changi’s Jewel Airport, a 137,000sqm “indoor sanctuary” connected to terminals 1, 2 and 3, will enhance the offering even further when it opens on 17 April.
The £951m development adds a suspended trampoline, giant slide, indoor forest, hedge and mirror mazes and “foggy bowls” (a children’s park with mist clouds to chase).
The airport also has an array of shops (155 in total) and dining options (105) for travellers to choose from.
Jewel Changi will break a few national records with its attractions, and one of them is thanks to the Rain Vortex, which will be the world’s tallest indoor waterfall.
The 40-metre (131-foot) beauty, which will light up at night, will be part of the stunning 40,000 square-metre (430,550 square-foot) air-conditioned attraction, Canopy Park, which includes gardens and walking trails.
Canopy Mazes will the largest hedge maze in Singapore – there, another record broken.
