I have travelled to Thailand many times and have never been asked to show a return flight even though I have always had one, what I have read here worries me though I have done this twice now, come to Thailand on a two month visa and then extended it another 30 days, my return flight was at the end of the 90 days but I here people say your return flight must be just for the 60 days so if I was asked by the air line when boarding I would be refused because I had a 90 day return, is that right?
