Frequently asked questions

Can I leave Changi Airport during a layover?
Usually yes, if your layover is at least 4.5 hours. You need about 130 min for immigration, 40 min each way in transit, and 75 min to get back through security — so aim to be at the gate with margin.
How long does immigration take at Changi Airport?
Budget about 130 minutes as a planning estimate. It can be quicker off-peak and slower after several wide-body arrivals land together.
How do I get from Changi Airport to Singapore?
The Metro MRT East–West Line reaches Marina Bay / City Hall in about 40 minutes — the simplest, most predictable way to get in and back in time.
Do I need a visa to leave the airport in Singapore?
Changi has a large transit area; some nationalities also qualify for the Visa-Free Transit Facility to enter briefly. An SG Arrival Card is required if you clear immigration. Always verify the official source before you fly.
Is there sterile transit at Changi Airport?
Yes. On a short connection you can head straight to your next flight without clearing immigration, staying inside the international transit area the whole time.
What if I don't have enough time to leave?
Stay airside and use what the terminal already offers: sleep pods, showers, lounges. It's the safer call whenever the margin is tight.
Is it worth leaving on a short layover?
Only if you have at least 75 extra minutes beyond the recommended minimum. When in doubt, staying near the gate beats risking the connection.
