Onward ticket for Thailand

Travellers from many countries can enter Thailand without a visa. That visa-exempt entry comes with a condition that catches a lot of one-way travellers: you may be asked to show that you will leave before your permitted stay ends.

Thai immigration can ask for it on arrival, but the check you are most likely to meet is at the airline counter before your flight to Thailand. If you have a one-way ticket, expect to be asked.

What Thailand asks for

Thai embassies list a confirmed onward or return ticket among the conditions for visa-exempt entry, together with a passport valid for at least six months and proof of funds. The amount usually given is 20,000 baht per person or 40,000 baht per family, in cash or an equivalent.

The length of visa-exempt stay depends on your nationality and has been changed more than once in recent years. Check the current figure for your passport on the Thai embassy or Ministry of Foreign Affairs website before you book anything.

Date it inside your permitted stay

The onward flight is evidence that you'll leave before your stay runs out, so its date has to fall within your visa-exempt period. A reservation dated after the last permitted day doesn't show that, and an agent checking the dates will notice.

If you plan to extend your stay at an immigration office in Thailand, the date still has to fit the period you are entering on. The extension is decided later and isn't guaranteed.

Leaving overland to Laos, Cambodia or Malaysia

Plenty of travellers leave Thailand by bus or train. Whether a bus ticket counts as onward travel is up to whoever checks it. Immigration may accept it, but airline check-in staff are often instructed to look for a flight.

If you are leaving overland, a flight reservation out of Bangkok, Phuket or Chiang Mai is the version every check-in desk understands. You don't fly on it; it just satisfies the check.

Thailand Digital Arrival Card

Foreign travellers entering Thailand also need to complete the Thailand Digital Arrival Card (TDAC) online, within three days before arrival. It asks for your travel details, so have your onward or return date ready when you fill it in.

Time the hold for check-in

The reservation has to be active when the check-in agent looks it up, which is the start of your trip, not the date you book it. Holds last from a few hours to several days depending on the airline, so book close to your departure.

Each flight in the search results shows roughly how long it holds. For a same-day or next-day departure, most fares are long enough.

Frequently asked questions

Does Thailand really check for an onward ticket?+

It can. Thai immigration lists an onward or return ticket as a condition of visa-exempt entry, and airlines flying to Thailand often check it at check-in because they are liable if you are refused entry.

Can I show a bus ticket to Cambodia or Laos instead?+

Sometimes. Immigration may accept it, but airline check-in staff often want to see a flight. A flight reservation is the option that works at every counter.

How long can I stay in Thailand without a visa?+

It depends on your nationality, and the length has changed several times recently. Check the current rules for your passport on the Thai embassy website before you travel.

What date should the onward flight be?+

Any date within your permitted visa-exempt stay. A flight dated after your last permitted day doesn't show you'll leave in time.
