What’s the rhyme or reason on the lack of consistency with showing vaccine or other documentation traveling around Thailand?
As an example;
Traveling from Phuket airport to BKK i was not asked to show vaccine info. BKK to Phuket I was also not asked.
The ferry from Phuket to Phi Phi I was asked for it and told it is mandatory and again taking the ferry back to a Phuket I was told I must show it.
That doesn’t seem to make any sense.
TLDR : Answer Summary
Travelers in Thailand have noted inconsistencies regarding the requirement to show vaccine documentation when traveling between different locations, such as from Phuket to Bangkok and vice versa. While some ferry operators enforce strict checks, airlines may not require any documentation at all. This discrepancy is attributed to a lack of standardized enforcement and varying provincial requirements, leading to confusion among travelers.
