or like this person, you can find your backbone and stand by your principals. Some people just don’t like people screwing them, I am one also. And others love it.
We are facing almost exact same situation and and timeline. But coming from Australia.Not sure either exact dates going into Lao which is the problem. Worst case buy the ticket in the airport checking line if you are refused by airline.Good luck.
years ago we travelled many times and a return ticket 6 months later to our home always worked once we told them our overland travel plans eg. Malaysia Singapore Indonesia home to Aust. But same a bit nervous doing this in a months time. My fall back is I will buy a throw away ticket in the line. Just don’t get to the airport late to give enough time to do this if needed.
