With eight hours or more between flights in Bangkok, you can usually leave the airport and see something, as long as your nationality can enter Thailand visa-free (or you hold a visa), you file the free TDAC arrival card, and your bags are checked through or stored. Plan on about three hours in total for immigration, getting in and getting back, and use the trains, not the roads.
Bangkok is a common stopover between Europe and Australia, between China and South Asia, and for budget connections across Southeast Asia. Many transit passengers never leave the terminal, which is a shame: Wat Pho, the river and Chinatown are within reach of both airports by rail. But a layover is not the moment to take risks with immigration rules or traffic.
This page explains the entry rules that apply when you step out of the airport, what to do with luggage, how much time the trip into the city really takes, and three plans for 8, 12 and 24 hours. Rules are as of October 2026.
Layover checklist
- Minimum time
- About 8 hours between flights for a short trip into the city; less is not worth it
- Entry

- Arrival card
- TDAC needed if you pass immigration; free at tdac.immigration.go.th

- Airport Rail Link, 05:30–24:00, to Makkasan (MRT) and Phaya Thai (BTS)
- Into town from Don Mueang
- SRT Red Line, about 05:00 to midnight, then MRT at Bang Sue
- Back at the airport
- We suggest at least 3 hours before an international departure
Can you leave the airport on a layover?
Leaving the airport means passing Thai immigration and entering the country, exactly like a tourist. There is no special "layover pass". Whether you can do it depends on your passport:
- Visa-exempt nationalities. Since 15 September 2026, citizens of 60 countries and territories, including the UK, USA, most of Europe, Australia, India, Japan, Singapore, Malaysia and Taiwan, can enter visa-free for up to 30 days for tourism. Our guide to the visa exemption has the full list; the old 60-day rule no longer applies.
- Bilateral agreements. Citizens of China, Hong Kong, Macao, Vietnam, Laos and several others get 30 days under separate agreements; Korea and Brazil, among others, get 90 days. Chinese travelers can read our guide to the mutual visa exemption.
- Everyone else needs a visa before arrival (a transit or tourist visa through the official e-Visa portal, thaievisa.go.th) or, for Azerbaijan, Belarus and Serbia only, a visa on arrival.
The general rules on longer stays are summarized on our visa and retirement page. On a layover, two details matter. Immigration may ask for proof of funds (10,000 baht per person, or 20,000 per family, in cash or equivalent) and evidence of onward travel, which your next boarding pass or e-ticket provides. And the UK government's travel advice says visa-exempt entry for tourism is "normally limited to two entries per calendar year", while Thailand's tourism authority ties that limit to land-border entries. If you transit through Bangkok often and plan to leave the airport each time, check with the Thai embassy first.
Your layover is an entry to Thailand, with every rule that comes with it. You need the TDAC, your passport must be valid for six months, and Thai law applies from the moment you pass immigration. If you are unsure whether your nationality is visa-exempt, stay airside; missing an onward flight because of a refused entry is far worse than a missed temple.
The TDAC arrival card and the immigration queue
Everyone who passes Thai immigration must file a Thailand Digital Arrival Card (TDAC) on the official site, tdac.immigration.go.th. It is free; sites that charge a fee are not official. You can submit it up to three days before arrival, including the day you land. Transit passengers who stay airside and do not pass immigration do not need one. Our guide to the TDAC explains the form.
Fill it in before your first flight if you think you might leave the airport; it costs nothing if you then stay inside. Immigration queues at Suvarnabhumi can be long at peak arrival times, and you pass immigration again on the way out, so build both into your plan.
What to do with your luggage
Through-checked bags. If both flights are on one ticket and your bags are checked to your final destination, they stay in the system. Ask at check-in to be sure. You leave with only your hand luggage.
Separate tickets. If you booked two separate tickets, you must collect your bags, pass customs and check in again for the next flight. That alone needs a generous margin. Suvarnabhumi has a 24-hour left-luggage service on Level 2 (near Gate 4) and Level 4 (behind row P); our luggage storage guide has the prices and other options. Do not carry a suitcase around the old town in the heat.
Switching airports. Arriving at Don Mueang and leaving from Suvarnabhumi (or the other way) is common with budget airlines. The free shuttle between the airports is only for passengers connecting between flights, with an onward ticket and passport, and the road trip can take more than an hour. Our guide to Bangkok's two airports explains the difference. With an airport change, treat any sightseeing as a bonus.
How long the trip into the city really takes
From Suvarnabhumi (BKK), the Airport Rail Link runs from 05:30 to midnight from Level B1 of the terminal. It does not get stuck in traffic. Change at Makkasan for the MRT Blue Line, which takes you to Sanam Chai (Wat Pho and the Grand Palace), Wat Mangkon (Chinatown) or Sukhumvit; or ride to the end at Phaya Thai for the BTS. Taxis from the official Level 1 queue run 24 hours (meter plus 50 baht and tolls), but Bangkok's roads are slow at rush hour. Our guide to Suvarnabhumi to central Bangkok covers each option.
From Don Mueang (DMK), the SRT Red Line runs from about 05:00 to midnight to Krung Thep Aphiwat (33 baht), where you change to the MRT Blue Line at Bang Sue. One stop south, Kamphaeng Phet puts you at Chatuchak Market; further on, the line reaches Sukhumvit, Chinatown and the old town. Our guide to Don Mueang to central Bangkok has the details.
Our rule of thumb for planning: allow about an hour from landing to leaving the terminal (longer at peak times), about an hour each way between airport and old town by rail with changes, and be back at the airport three hours before an international departure. On an eight-hour layover, that leaves roughly three hours in the city.
Plan 1: eight to ten hours, Wat Pho and the river
Take the Airport Rail Link to Makkasan and the MRT Blue Line to Sanam Chai. Walk to Wat Pho (300 baht, open 08:00–19:30), see the Reclining Buddha and, if time allows, have a 30-minute foot massage at the temple's massage school (340 baht). Cross by the small ferry from Tha Tien pier to Wat Arun if you have an extra hour. Then head straight back the same way.
Wat Pho's long opening hours make it the best single sight for a short layover. The Grand Palace sells its last tickets at 15:30 and needs two to three hours on its own, which is usually too much. Our guide to Wat Pho and Wat Arun describes both temples and the ferry. Wear long trousers or a long skirt and covered shoulders.
Plan 2: twelve to sixteen hours, temples by day and Chinatown by night
With a daytime arrival and a late-night or next-morning departure, you can do much more. Spend the morning at the Grand Palace and Wat Pho, rest through the hottest hours, then take the MRT two stops from Sanam Chai to Wat Mangkon for an evening in Chinatown, where street food fills Yaowarat Road after dark (many street stalls take Mondays off). Return to the airport by MRT and Airport Rail Link, which stops at midnight, or by taxi.
On a Saturday or Sunday, swap the palace for Chatuchak Weekend Market in the morning; it is especially convenient from Don Mueang.
Plan 3: a 24-hour stopover with a hotel night
A full day lets you sleep in a bed, which after a long-haul flight is worth more than any sight. Choose a hotel near a rail station on the line back to your airport: near the MRT for Don Mueang, near the Airport Rail Link or a station on the Blue Line for Suvarnabhumi. Our guide to where to stay in Bangkok compares areas by station. Then follow day one of our three-day itinerary: temples in the morning, the river in the afternoon and dinner by the water.
A hotel next to the airport is a better choice only for a very late arrival and an early departure, when you will not go into the city at all.
Money, data and other practical points
- Cash. Withdraw a small amount at the airport for ferries, food stalls and temple fees. Foreign cards pay an ATM fee of 250 baht (Visa, UnionPay) or 350 baht (Mastercard at some banks) per withdrawal, as of October 2026.
- Trains. The MRT accepts contactless Visa, Mastercard and UnionPay cards at the gates, which saves time; the Airport Rail Link has taken contactless cards too since November 2025, while the BTS still uses its own tickets or a Rabbit card.
- Data. A tourist SIM or eSIM lets you use maps and Grab; the shortest AIS and True plans start at a few hundred baht. See our article on SIM cards and eSIMs.
- Heat and clothes. Wear temple-appropriate clothes from the plane, and carry water.
- Back on time. Set an alarm for when you must head back, and stick to it whatever the traffic map says.

Frequently asked questions
Can I leave Suvarnabhumi airport during a layover?
Yes, if you can enter Thailand: either your nationality is visa-exempt (30 days for 60 countries as of October 2026, or a bilateral agreement) or you hold a visa. You pass immigration like any arriving visitor, need a TDAC arrival card and must clear immigration again on departure.
How many hours do I need to leave the airport in Bangkok?
We suggest at least eight hours between flights. Immigration, the train into the city and the trip back, plus three hours at the airport before an international departure, take about five hours, leaving roughly three hours to see Wat Pho or another sight close to the MRT.
Do transit passengers need to fill in the TDAC?
Only if they pass immigration. Transit passengers who stay airside do not need a TDAC, according to the official FAQ. If you leave the airport, even for a few hours, you must file one, free of charge, on tdac.immigration.go.th, up to three days before arrival.
Can I store my luggage at Bangkok airport during a layover?
Suvarnabhumi's left-luggage counters on Levels 2 and 4 are open 24 hours and charge per piece per 24 hours. If your bags are checked through to your final destination on one ticket, you do not need it, because they stay in the airport system.
What is the best thing to do on a short layover in Bangkok?
Wat Pho, with its Reclining Buddha, is the most practical choice: it is near MRT Sanam Chai, open daily from 08:00 to 19:30 and can be seen in an hour or two. With more time, add Wat Arun across the river or an evening in Chinatown.
