Will my return ticket be an issue if it shows I'm staying for 61 days after extending my 30-day visa exemption in Thailand?

and we're done.

IF the O/P can't figure out what to do with all those comments and suggestions, they should probably not come here :O ;) :P

I think most airlines know you can extend the30 day visa exempt by another 30 days now so I don't think you will have much of a problem,just even print off the page showing about the 30 day extention and show the airline and explain that to them,this will cover your 60 day holiday,30 plus 30 days.as others have said 1 day overstay at airports is free.

he could do that and get a 60+30 days Single Entry Tourist Visa, yet he mentioned that this is not for him. He said before: " I won't be getting a visa though, i plan on entering on a 30 day visa exemption and then getting a 30 day extension"

When I first came here I received a 90 day visa from the Thai Embassy in my country (USA)Before I came.

The problem is the airline on his first flight will not allow him to board because his out of Thailand flight is not within the first 30 days. He should buy a both ways flight out of Thailand to Vientiane oder Siem Reap on day number 28 or 29 and allow himself a holiday for 3-4 days. Then return to Thailand. In which case he will not only never be in overstay and it is btw cheaper than changing your ticket. A ticket out of Thailand within the first 30 days will guarantee that the airline of his first flight will let him board. Also when he returns from the neighbour country to activate the next 30 days visa exempt, his original 61st day return ticket is important, as it is within the 30 day timeframe and thus the airline in the neighbour country will allow him to board. All other options considered, I would not risk to go to my home country's airport unprepared without a Visa for Thailand and a return flight 61 days later. That's already where his journey will end

You may have a problem boarding your flight without a visa or a return/onward travel within 30 days

500 thb fine for overstay. If on weekend you are probably lucky..

you could buy a both ways flight out of Thailand to Vientiane oder Siem Reap on day number 28 or 29 and stay there for 3-4 days. Then return to Thailand. In which case you will not be on overstay and it is probably cheaper than changing your ticket. A ticket out of Thailand within the first 30 days furthermore will guarantee that the airline on your first flight will let you board. This aspect of refusal of boarding because your return ticket shows it is OUTSIDE of 60 days may indeed become a problem otherwise

If it's your first trip to Thailand it's overwhelmingly likely that the biggest problem you will have is with the airline you're flying with, not with immigration.

Okay, it seemed we wandered off topic :O

AS A GENERAL RULE if you have an overstay of under 24 hours they waive the 500baht fine when you stamp out to fly out of the country and all you get is a small stamp in thai next to your triangular departure stamp.

That stamp looks like this...

An overstay of 1 day is not a problem, it says so in their documentation, it’s just a fine of 500 baht. Some will disagree but that’s the official word. As I mentioned in a previous post, the immigration officer did not let me obtain a 30-day extension because it was cheaper to pay the 2-day overstay rather than the extension. And while onwards travel is something they can check, I haven’t arrived in Thailand with onward travel in about 5 years. And yes, I realize they can check next time and I might get turned away.

So, based on some facts (the overstay not being a problem) and some personal experience (yours may differ) I wouldn’t worry about changing your ticket, I’d just play the 500 baht at the airport on the way out of Thailand.

You won't have a problem extending 30 day's they don't ask to see your plane ticket and no problem at the airport. The only problem is getting caught on the way to the airport.

They won't let board the plane !
