Where can I find a temporary booking service for an exit flight from Thailand?

Garrett Greenwald , If you want to persist, I can do nothing for you. I traveled in November. Brussels - Frankfurt - Bangkok. In Brussel, I was denied boarding pass for Bangkok, as it will take him an hour to check if indeed, I would be on that plane out of Thailand. Told me to try in Frankfurt. I refused, and said I was not going to stand in line there again and pick up my suitcase. He then finally phoned, checked, and that was not done in an hour, but 3 minutes. Why take the risk, if even there is the smallest possibility, the COULD check it? Nort worth 10 dollar, don't you think so? If you flight is cancelled already, you are not travelling, point.
