How does transit work at Changi Airport?

To qualify as a Singapore Airport transit passenger, you must ensure that both your flights are booked in the same booking itinerary and that your check-in luggage is tagged through from the origin airport to their final destination. Afterwards, you're left to do anything you want during your layover.



Transiting at Singapore Changi Airport (SIN) in 2026 is designed to be a "frictionless" experience. If your baggage is checked through to your final destination and you have your onward boarding pass, you simply land and stay within the airside (transit) zone. You can move between Terminals 1, 2, and 3 using the free, 24-hour Skytrain, which takes only minutes. For Terminal 4, you use a free shuttle bus. Changi is famous for allowing transit passengers to enjoy world-class amenities like a cinema, rooftop swimming pool, and butterfly gardens without ever clearing immigration. If you have a layover longer than 5.5 hours, you can even join a Free Singapore Tour (provided you meet visa requirements or the "Visa-Free Transit Facility"). The most important thing for 2026 travelers to remember is that you will undergo security screening at the individual boarding gate, so you don't have to wait in a massive centralized security line upon arrival.
