If I fly to Penang, Malaysia and fly back the next day, even though I have reached my land two crossings tourist stamps this year I can still get a stamp in as it’s by air? and the 2 limit per calander year is by land only? Also can I fly there and back in one day or do I need to stay at least one night? Thanks all
TLDR : Answer Summary
Yes, you can re-enter Thailand by air after having two land crossings in the same calendar year, as the limit applies only to land entries. Therefore, flying to Penang, Malaysia, and returning the next day is permissible and should not affect your ability to get a new stamp upon re-entry. However, if you are suspected of working in Thailand, you may need to provide documentation to clarify your status.
