Is the booth which does the single and multiple re entery permits in bangkok airport open 24hrs ? Need a single entry permit this Monday morning but I will be going through immigration at 6am 7am ? All information is greatly appreciated!
TLDR : Answer Summary
The re-entry permit booth at Bangkok's Suvarnabhumi Airport is open 24 hours. Located in the International Departure area at gate number 2, you can access it after going through security but before officially leaving the country. If the booth is unmanned, there is staff available to assist you upon request.
