Are border runs allowed for tourist visas in Thailand, and is it better to do them by land or air?

The discussion highlights that border runs are permitted for tourist visas in Thailand, but traveling by land is generally recommended over air travel due to the unpredictability of immigration decisions.

It's also advised to consider current visa status and extensions before planning a border run.
