As a significant gateway to Southeast Asia, the city-state has an aviation infrastructure that places travellers just a short distance from the urban core upon arrival. Most passengers who book a flight to Singapore will arrive at a single, globally recognized facility that handles the vast majority of international traffic for the island.
Changi Airport (SIN)
Singapore Changi Airport, identified by the code SIN, is situated approximately 20 km east of the downtown core in the Changi district. It is the primary hub for Singapore Airlines, Scoot, and Jetstar Asia, including four main passenger terminals connected by an automated people mover system and pedestrian walkways. The airport is a major transit point for long-haul flights to Singapore and other regional destinations across Asia and Oceania.
Upon landing, the Mass Rapid Transit (MRT) system provides a convenient connection to the city via the Changi Airport MRT Station, located in the basement of Terminals 2 and 3. Travellers can reach the City Hall or Raffles Place districts in about 30 minutes, typically requiring a quick cross-platform transfer at Tanah Merah Station. For a direct route to specific accommodations, the Airport City Shuttle departs regularly for most downtown hotels, while public buses, such as Line 36, offer a scenic though slower journey to Orchard Road. Taxis and ride-hailing services are available 24 hours a day at designated bays, providing a 20-minute trip to the Central Business District depending on traffic conditions.
Seletar Airport (XSP)
Seletar Airport, or XSP, is located in the northeastern region of the island, roughly 15 km from the city centre. While it originally served as the main international gateway before the opening of the larger eastern hub, it now primarily manages secondary scheduled commercial flights, private aviation, and charter services. The airport operates from a single, passenger terminal that caters specifically to turboprop aircraft, notably serving regional routes to nearby Malaysian destinations.
Accessing the heart of the city from this terminal is convenient by taxi or ride-hailing applications, with a journey time of approximately 20 to 25 minutes to reach Marina Bay. While there is no direct train link to the terminal building, travellers can take public bus Line 102, which connects to the Sengkang MRT Station. From there, the North East Line provides a direct rail link to central areas like Dhoby Ghaut and Chinatown in about 30 minutes.
