Hi Mags
It must nerve racking waiting for news about the situation in Thailand.I guess you have no choice and it's a matter of waiting and keep in contact with your airline. I know, I'm no help... sorry!
I've just read this report:
Bangkok Post | General news | Airports cannot be reopened quickly
My guess (and it it a guess) that after reading that link aircrafts may be redirected to other airports for a while until the airport is up and running again.
Cheers Geri
