What happens if you are denied entry to Thailand? Can you fly to another country instead of being sent back?

Okay, what controls where you have to go when you get a denial of entry at an airport is NOT the thai immigration officers :O it is the airline you flew in to thailand on. :(

Let me say that one more time so you people have got your head around it. The people that control where you have to go and how you have to go when you are denied entry into thailand at an airport are NOT the immigration officers it is the AIRLINE you flew here on. That's why some will let you go to any country you can get into without a visa, some will let you go back to where you just came from and some make you fly back to the country of passport origin. It is the airline policy on how that specific airline handles people who are denied entry that controls where and how you leave thailand.

If it is a land border, they usually will not stamp you in unless you make a fuss. In which case they will actually place a refusal stamp in your passport with a reason.

Airport bordet they will send you back on the same airline that you came from :(

In cases that you are detained and deported, you can be forced to buy a ticket elsewhere or your home country.

Hmm, immigration may be slow to let you fly elsewhere as if you were refused there the airline would only be responsible to return you to Thailand.

The airline also has the right to refuse boarding, and they do keep checks on visas across ASEAN. Speak with immigration, find out why they denied you, see if you can sort it. Don’t risk losing money on a flight and being denied boarding let alone arriving at the other countries immigration.

No matter if you have a visa or not, if you're denied entry at the airport it is totally up to the immigration officers if they'll let you go to a country you can get into without a visa OR if they send you back to the country your passport comes from.
