What should I do if my flight from Thailand is cancelled or if I want to re-enter after exiting?

Go and ask Immigration, it maybe all over by then but I have my doubts.

N9 fly out

I would personally do a border run now and stay a week or so. Come back and you'll have another 60 days to figure things out. The war is quite unpredictable now and could still be going on a year from now or be over any day. Give yourself a wide margin so it's a not a huge concern pending.

The 4th April is a long way away in terms of the war in the middle east. Anything could happen before then

If your flight is cancelled and you have proof you won't be charged overstay fees

As any extension will be down to the Thai Immigration office they are the only people who can answer so I would recommend that you go to an Immigration office and ask them and not bother getting advice online. I know I am giving advice online.

We’ve tried this we also have done 90 days only got a 7 day extension dispute flights been cancelled and we’ve rebooked alternative route via India too uk also looks uncertain for Monday nightmare 🙈visa also finished then

No charge for overstay if your flight is cancelled due to the problems, friend left the other day just show details of flight cancellations at immigration.

If your flight is cancelled you are still responsible for leaving Thailand before your permitted stay expires. Flight cancellations normally do not qualify for an additional extension. In practice you must arrange another flight. If necessary, immigration can issue the standard 7 day extension denied stamp, which gives you seven days to depart.

If you leave Thailand and attempt to re-enter after a few days, you may receive a new visa-exempt entry. However, entry is always at the discretion of the immigration officer. Given that your previous stay in 2025 and the current stay together approach around six months, you are already close to the upper range typically tolerated for visa-exempt tourism.
