I’ve heard of some folks just buying a ticket when the ticket counter stops them, so as long as you leave yourself sufficient time, you should be fine.
I’ve only had the gate check again when going to Vietnam. That was with Air Asia. I expect they encounter more problems than most since they’re local, but, boy, were they a nuisance.
I can’t speak for entering Thailand now because I’m on a non-O extension. The last time I entered as a tourist was in June, because my passport had been stolen. Hopefully, I won’t be entering as a tourist again for a long, long time. 🤞
