Will Thailand change its entry rules for visitors from the U.K. due to the rising omicron variant?

Nobody knows....

Those who know won't post on fb and those who opine on fb don't know.

This from Richard Barrow. “The Minister of Public Health is proposing for Test & Go to be scrapped and quarantine brought back for all international arrivals. This is despite the fact that only 0.14% of Test & Go arrivals tested positive. Even talking aloud about this plan will be disastrous for tourism.”

Here's where you are most likely to find the best answer:

Something to keep in mind though is the requirement to enter Thailand is stricter than European countries . In Thailand you need to be vaccinated , have a negative test before hand , and a negative test on arrival before you are allowed out. That catches a lot more people from coming in with covid than just requiring a vaccine or vaccine and test before flight like European countries do. My guess would be they would only take off Britain from test and go if they saw significant numbers of British nationals testing positive on arrival. But no way to know for sure.

I can't understand these questions Tbh. You either book or you don't.

I fly Thursday, hope nothing change

only the Thai govt would know and let's hope that they don't change their minds!

The next 48 hours will tell us fingers crossed for you

It's always possible and a risk of traveling during a pandemic. Likely IF they change anything, it will be removing a country from the safe list for test&go eligibility and making them use a sandbox or quarantine entry.

Nobody knows rules can change quickly if goverment think its required.

No one knows for certain and anyone who says yes or no is just guessing. My guess is no, but it's just that, a guess.
