Possibly. I was questioned a few months ago and didn’t (first time I can remember being questioned). I had quite a bit of money on me but had to sign a waiver promising to leave. Next time I go, if on a tourist or visa-exempt, I’ll definitely have a ticket.
I was asked last time I entered a couple months ago flying into Phuket. This was at immigration, not the airline. I didn’t and was pulled out of line to show proof of funds and sign a waiver promising to leave. They were nice about it as far as immigration goes for whatever that’s worth. I’ve also heard more instances that they're becoming more strict with that. If you don’t, I’d recommend you have plenty of cash on you, ideally baht.
Wow, even a year? Awesome. Yea, I when I was in China a while ago a visa had a stipend that you needed to enter within 30 days or something like that so just wanted to make sure. Thanks for answering mate.
