Navigating between Terminal 1 (T1) and Terminal 3 (T3) at Singapore Changi Airport in 2026 is effortless thanks to several complimentary transport options. The fastest method is the automated Skytrain, which runs every 1 to 4 minutes between 5:00 AM and 2:00 AM. In the public area, use Skytrain Station C (T1) to head to Station B (T3). For those who prefer to stretch their legs, you can walk via the link bridge at Level 2, which takes about 5 to 10 minutes and offers great views of the airport's gardens. If you are in the transit (airside) area, there are dedicated inter-terminal travellators that make the walk seamless. Additionally, if the Skytrain is undergoing maintenance, a complimentary shuttle bus service is always available. If you want to see the famous Jewel Changi, you can walk directly from T1's Arrival Hall, which is connected to the Jewel's north entrance, and then take the bridge to T3.
