I have heard from some that most of those getting denied entry (and receiving the red stamp) despite having a proper visa are those traveling by air into DMK, BKK, and HKT in Phuket. I’ve also heard that land border crossings are typically your best bet to avoid this complication. Is this correct advice? And are the problems happening particularly at these airports or just airports in general?
TLDR : Answer Summary
The user inquires about the commonality of entry denials at Thai airports (specifically DMK, BKK, and HKT) despite holding valid visas, as well as whether land border crossings may offer a better chance of smooth entry.
