Singapore Changi is the most decorated airport in the world, named best by Skytrax for a record 13th time in 2025, and it matched the honors with volume: a record close to 70 million passengers in 2025 through four terminals and the Jewel, the nature-filled complex whose indoor waterfall made Changi a destination in itself. It is the fortress hub of Singapore Airlines and the great crossroads of Southeast Asia.

Changi is now building its future: Terminal 5, whose construction began in 2025 on the airport's eastern land bank, will handle about 50 million passengers alone when it opens in the mid-2030s, roughly doubling Changi's size and consolidating a third runway into civil operations, Singapore's answer to the mega-hubs rising across Asia and the Gulf.

Terminals & infrastructure

Changi's four terminals and the Jewel, the glass toroid whose 40-meter indoor waterfall is aviation's most photographed sight, form the benchmark airport experience, crowned world's best by Skytrax for a record 13th time in 2025. Construction of the gigantic Terminal 5 began in 2025 for a mid-2030s opening that will roughly double capacity, with a third runway being integrated into the civil airfield to serve it.
