Navigating between Terminal 3 (T3) and Terminal 1 (T1) at Singapore Changi Airport is exceptionally convenient and free of charge. The most popular method is the Skytrain, an automated people mover that runs frequently between both the "Public" (landside) and "Transit" (airside) areas. In the transit area, you can take the Skytrain from Station C (T1) to Station B (T3) in approximately 4 minutes. If you prefer to stretch your legs, you can walk between the terminals via the inter-terminal walkways, which are fully air-conditioned and well-signed. Walking from T3 to T1 typically takes about 10–15 minutes and allows you to pass through the Jewel Changi Airport complex, where you can view the HSBC Rain Vortex. In 2026, these connections remain a benchmark for airport efficiency, operating from 4:30 AM to 1:30 AM for the Skytrain, while the walkways and shuttle buses are available 24/7.
