Changi Airport
Changi Airport (IATA: SIN, ICAO: WSSS) is the main international airport of Singapore, and functions as one of the most significant aviation gateways in the Asia-Pacific region. Situated within the Changiplanning area in the eastern part of the country, the airport is approximately 24 kilometres (15 miles) east from the Central Area and occupies a site spanning about 25 square kilometres (9.7 square miles). The airport is a base for more than 100 international carriers with scheduled services linking Singapore to destinations across Asia, Oceania, Africa, Europe, the Middle East and North America. As of 2025, Changi Airport handled about 70 million passengers and ranked the 16th busiest airport by passenger traffic as well as the 4th busiest international airport by seat volume based on OAG's records.
Changi Airport serves as the headquarters for several aviation and ground handling entities. It is the home base of Singapore Airlines, the nation's flag carrier, along with its associated subsidiaries Singapore Airlines Cargo and Scoot, a regional low-cost carrier. The airport also hosts the operations of BOC Aviation, a major aircraft leasing firm. Ground and catering services are provided by SATS and dnata Singapore (formerly CIAS), whose facilities are located within the airport precincts. Owing to Singapore's central geographical location and high volume of international transit traffic, the airport has also been designated a principal cargo hub by FedEx Express, reinforcing its logistical and commercial importance within global air transport networks. The airport is managed by the Changi Airport Group, a corporate entity owned by the Singapore Government while solely maintained by the Ministry of Finance.
The airfield infrastructure comprises three operational runways, each measuring 4 kilometres (2.5 mi) in length. While the main airport code is WSSS, the third runway, designated 02R/20L, was formerly part of the adjacent Changi Air Base (East) and used by the Republic of Singapore Air Force (RSAF), carrying the ICAO code WSAC. The terminal complex includes four passenger terminals, of which Terminals 1, 2 and 3 are directly connected to Jewel Changi Airport, a mixed-use development featuring retail, dining and entertainment facilities integrated with airport infrastructure. A fifth terminal is currently under construction.
