Most Indian travellers changing planes in Thailand do not need a transit visa: if you stay inside the international transit area at Bangkok’s Suvarnabhumi (BKK) or Don Mueang (DMK), have a confirmed onward ticket leaving within about 12 hours, and your bags are checked through to your final destination, you transit without any Thai visa (Thai Visa Services, accessed 2026-07-21). You only need entry permission when you must pass through immigration, and for Indians that is usually a Visa on Arrival or a tourist e-visa (the visa exemption having been withdrawn, with a 30-day replacement approved but not yet in force), not a dedicated transit visa.

When Indians can transit Thailand without a visa
You can transit airside without any Thai visa when you remain in the international transit zone and simply connect from one international flight to another. All of these conditions must hold (Thai Visa Services; VIZA transit guide, both accessed 2026-07-21):
· you stay inside the international transit area and do not pass through immigration;
· you hold a confirmed onward ticket leaving Thailand, generally within about 12 hours and on the same calendar day;
· your baggage is checked through to the final destination, so you do not need to collect and re-check it;
· your onward flight is to a third country, not a domestic Thai sector.
Bangkok’s Suvarnabhumi has the most complete international transit area of the Thai airports, which is what makes airside connections there straightforward.
When you do need to clear immigration
You need entry permission, not just a boarding pass, the moment you leave the transit area, and that happens in a few common situations. You must clear immigration if you want to leave the airport during a long layover, if you have to collect and re-check your baggage, or if your connection means switching airports, most often between Suvarnabhumi (BKK) and Don Mueang (DMK), which are separate airports on opposite sides of Bangkok. A stay of more than about 12 hours in the airport can also push you past the airside transit allowance.
For an Indian passport holder, clearing immigration in these cases does not require a separate transit visa, because India can enter Thailand for tourism on a Visa on Arrival or a tourist e-visa. In practice that means you enter on the same route a tourist would use, then re-enter the airport for your onward flight. Note that entry is itself in transition in 2026: the earlier 60-day visa exemption was withdrawn (2026-05-19) and a 30-day replacement was approved but not yet in force as of 2026-07-21, so travellers use the Visa on Arrival or e-visa in the interim; confirm the current position before you rely on it (Nation Thailand, accessed 2026-07-21).
The formal Thailand transit visa (category TS)
Thailand does issue a dedicated Transit Visa, but it is aimed at nationalities that lack visa exemption, so few Indian tourists need it; where it applies, it costs THB 800, is valid three months and allows a stay of up to 30 days per entry. It is applied for at a Royal Thai Embassy or Consulate before travel, with no on-arrival option, and processing takes about 3 to 5 business days (Thai Visa Services, accessed 2026-07-21). The THB 800 fee is about INR 2,300 at 1 THB = INR 2.87 on 2026-07-21 (XE). Typical documents are a passport valid six months with two blank pages, a confirmed onward ticket, a visa for the final destination if one is required, a recent photo and proof of funds of around THB 10,000 per person. Because an Indian can already enter for tourism on a Visa on Arrival or an e-visa, the transit visa is rarely the right route for an Indian traveller; use it only if an official source tells you the tourist routes do not fit your case.
Cover the risk that transit actually carries
The real exposure on a transit itinerary is not the visa; it is a missed connection, a delayed bag or a medical emergency far from home, and travel insurance is what handles those. Zurich Kotak’s Smart Travel policy for an Asia destination like Thailand is offered on the Excel and Prime tiers, with a sum insured up to USD 500,000 on Prime and a maximum entry age of 70 [insert current tier limits from fact sheet], covering emergency medical treatment, trip delay and missed-connection scenarios for listed reasons, and lost or delayed baggage, with claims handled by Europ Assistance India on a cashless or reimbursement basis. Whether you clear immigration or stay airside, take cover before you fly.

Frequently Asked Questions
Q: Do Indians need a transit visa for Thailand?
A: Usually no. If you connect between international flights and stay inside the transit area at Suvarnabhumi or Don Mueang, with your bags checked through and an onward ticket leaving within about 12 hours, you transit without any Thai visa (Thai Visa Services, accessed 2026-07-21). You only need entry permission if you leave the transit area.
Q: What if my layover means changing airports in Bangkok?
A: Suvarnabhumi (BKK) and Don Mueang (DMK) are separate airports, so switching between them means clearing immigration and re-entering. As an Indian passport holder you do this on a Visa on Arrival or a tourist e-visa, not a separate transit visa, since India can enter Thailand for tourism through those routes.
Q: How long can I transit in Thailand without a visa?
A: Airside transit without a visa is generally for layovers up to about 12 hours while you remain in the international transit area. Beyond that, or if you leave the transit zone, you need entry permission through a Visa on Arrival, an e-visa (or the visa exemption once it is in force) or, for some nationalities, a transit visa (VIZA transit guide, accessed 2026-07-21).
Q: How much does a Thailand transit visa cost?
A: The formal Transit Visa (category TS) costs THB 800, about INR 2,300 at 1 THB = INR 2.87 on 2026-07-21, is valid three months and allows up to 30 days per entry, applied for at a Royal Thai Embassy or Consulate (Thai Visa Services, accessed 2026-07-21). Most Indian travellers do not need it, because the Visa on Arrival or tourist e-visa route already covers them.
Q: Do I need the TDAC if I am only transiting Thailand?
A: If you stay airside and do not clear immigration, you are not formally entering Thailand, so the Thailand Digital Arrival Card is not triggered. If you clear immigration to leave the airport or change airports, you are entering the country and must complete the TDAC online within three days before arrival, like any other visitor.
