My family and I got a non-visa 30 day-entry permit into Thailand. Now we are in CNX, and I found that in our passports there is one day missing. According to the 30 day-regulation, our permit should end at Sept 10th, but actually it seems they did a mistake at IM and gave us only until Sep 9th. Now, all our flights back home are booked and confirmed for Sept 10th.

I read in this forum that this should not be a problem at all, if you just overstay one day and don't get cought before you get to the airport you will not even be fined. I would be OK with that kind of solution.

But --- we have a domestic flight first on Sept 10th from CNX-BKK, and the international flight out of BKK is the same day later at night. So, let's say we get to CNX airport to check in for our flight to BKK and they see that we overstayed one day, will they put us in jail and deport us, or will they be fine when I show them our flight ticket for the same day later out of BKK? Anybody with experience here, not just guessing around (I can guess myself...)?

Firstly what date did you arrive? The arrival date counts as day 1 of your stay.

If it really is wrong, visit CM immigration and get it fixed (free)

Alternatively you could visit immigration with your outgoing tickets and plead with them for a free extension.

Or, you could do nothing, I suspect you will be just fine on the domestic flight, check-in staff are only interested that you are who you say you are, they are unlikely to shop you to immigration

As Crossy says, the reason to show your passport on domestic is to verify that you are the person on the ticket and don't look at the visa stamp. Actually I never use my passport for ID on domestic, just my Thai DL with no problem.

But I don't have overstay experience so will not guess.

Crossy pretty well nailed it in one ....

Thanks for the explanation! Yeah, I didn't count day 1, then, so they are right with the stamp.

Agreed, lop! You got me here, and I really don't wanna break the law, am just in this awkward situation that I counted wrong...
