Is an exit ticket required for Americans entering Thailand?

You have 90 days then get out.

You’ll get completely different answers to this question because it’s up to the individual airline. Some people will never have been asked, some will always have been asked, and some a mixture of both.

There is no correct answer as you’ll only find out if you need one when you go to check in - or call the airline prior to check their policy.

With a visa, i'd say unless u dress like a bum u will not be asked for onward/return ticket

NO VISA and planning on using visa exempt ur chances are u will be asked for onward ticket by airlines

use onwardflights.com

i have been coming to Thailand for 20 years never bothered with a return ticket

Thailand profiles, and stereotypes, so if you fit into their stereotypes they will enforce things they don't enforce for others.

No they don't

I’m also American and have never had an onward ticket when entering Thailand. I’ve had airlines raise that issue when flying to some other countries, but normally they are satisfied if you just sign an indemnity form agreeing to be responsible for any costs they incur if you’re turned away at immigration and denied entry. They keep the forms somewhere at the check in area. I’ve never had it come up (for me at least) at the immigration counter.

Can only comment on experience. It technically states yes you do but ive never had 1 as I extend my stay and not exactly sure when I'll leave and last time I was there was march. Not at any airport on the way or airline immigration etc didnt even speak to me. I dont think they have the time to check

That depends on a lot of factors, none of which you have included in your question.

If you are traveling with a long-term visa then no you are not required to show proof of onward travel.

If you are traveling as a tourist (with a tourist visa, or no visa and planning to entire visa exempt) there are requirement to show proof that you'll be leaving within the number of days you will receive (60 or 30) and requirements to show that you have 20,000 baht or equivalent in another major currency IN CASH ONLY.

Neither of the above requirements are asked for by immigration often, in-fact they almost don't exist when you arrive in Thailand.

But your airline is very likely to ask you to show proof of leaving Thailand if you are traveling as a tourist, especially if it's with no visa at all. They will want to see you show them you have a ticket out of Thailand within the number of days you'll be receiving when you arrive, or they won't let you board your flight. It's best to check your airline for what their policy is on this before you get to the airport and forced to buy a ticket while standing in line.

Nah, if you cross the border for an extention and they ask wheres your return ticket, tell them your getting the train to Indonesia

yes. Actually the airline will require it unless you have a long term visa for Thailand.
