Are travelers from the 94 visa-exempt countries allowed to enter Thailand with a return ticket exceeding 60 days but within 90 days?

It will depend on your airline. Some airlines won’t jet you board without an onward ticket. I just flew in with air Asia and there was no issue with them . Nobody asked I’d had a visa before. Immigration just asked me how long I was staying and where I was going next.

They asked me, the lady said must have a ticket out within the 60 days if no visa. I showed her my 60 day tourist visa and everything was ok. Flight home within 90 days… 🤷‍♂️

My wife is Thai. I am flying to Thailand on 27th Dec on a 60 day return ticket, but will extend the 60 day visa to 30 days more, then change my return ticket when i am in Thailand. I thought that was the best way to do it, since i too couldnt find the answer to the same question.

Indeed, you won't find this in official rules. That's unfortunate because you certainly aren't the only one in this particular situation.

Another problematic aspect of this rule is that the only real enforcement of it is the pre-check of entry eligibility, done by airlines. Immigrations rarely check anyone for it. So now the interpretation suddenly depends on a party who can't deviate and is supposed to only strictly do as the rules state. Quite a messy situation.

The most commonly accepted interpretation of the rule, as unfortunate as it is, appears that extendability is not accounted for. Not saying that it makes sense, why would a country on one hand allow anyone to extend a visa and on the other hand require having booked an exit trip before the original date, but most airlines, if they check, appear to follow this rationale. But not all, some will allow you to get aboard with proof of onward travel within the 90 days instead of 60.

I've booked a 90 day return flight and a 90 day accommodation stay with a 60 day visa. No problem just tell the place you are staying (only if they question you on your passport date stamp) that you will be applying for a 30 day extention because they have to vouch for you on an immigration form (T30). But they can maybephone the hotel/owner where you're staying. Don't worry just do it. Or if you are concerned get a flexible flight ticket.

Buy a bus ticket to Cambodia on line or plane ticket to Cambodia and then you can show it to the immigration if they ask you, then you can cancel the tickets

Thai immigration won't care unless they're looking for a reason to deny entry. Your airline on the other hand might not let you board your flight without an onward flight from Thailand, it's them you need to ask

The consulate can't answer you for 2 reasons:

1) The consulate doesn't dictate airline policy

2) The consulate doesn't dictate immigration policy. Immigration is a different government agency.

Proof of onward travel is not normally asked for by immigration when you enter Thailand. But it is often asked for by your airline before they let you board your flight. So you need to check with your airline what their policy is for people flying to Thailand without a visa.
