Are all terminals at Changi connected?

Changi Airport currently has four terminals, T1, T2, T3, and T4, with a total passenger annual handling capacity of 90 million. Terminals 1, 2, and 3 are directly connected via a people mover system, with airside passengers being able to freely move between the terminals without going through immigration.



Yes, all passenger terminals at Singapore Changi Airport (T1, T2, T3, and T4) are connected, though the methods vary. Terminals 1, 2, and 3 are directly linked both "landside" (public area) and "airside" (transit area). In the transit area, passengers can move freely between these three terminals using the automated Skytrain system or by walking along integrated passenger bridges. The Jewel Changi Airport complex also serves as a central landside hub connecting T1, T2, and T3 via pedestrian link bridges. However, Terminal 4 is physically separated from the main cluster. To reach T4 from the other terminals, passengers must take a free shuttle bus service. Airside transit buses run between T4 and the other terminals for those with connecting flights, while landside shuttle buses are available for the general public. As of 2026, T4 remains an "odd one out" in terms of physical connectivity, requiring a short road journey, whereas the other three terminals function as a single massive interconnected transit zone.
