Changi has topped most global airport rankings for a decade and a half. Its Jewel complex holds a 40-metre indoor waterfall and is landside, so anyone can visit without a ticket — which is the point: the airport is treated as a national asset rather than infrastructure.
The other code, WSSS
Every airport has two codes. The three-letter IATA code, SIN, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, WSSS, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why WSSS looks nothing like SIN.
