Never happened to me before but I will be utilising a 60 day TV right up to the day. Then the airline pushed me further out 1 day on my return flight which will make it 61 days, the original flight cancelled. What are my options here? I'm thinking just turn up at the airport and pay the 500 baht fine but this was not of my doing but the airlines. I have the original e-ticket. What would a more experience person in this situation do? Thank you. 

If leaving from a airport from either airport in Bangkok you will not be fined for a one day overstay. A one day overstay is common due to flight changes and etc.

Thanks for that ubonjoe, much appreciated, I don't frequent here that much so I've been a bit out of touch, cheers. ????????????
