This was a very informative thread for me. I learned a lot from those who travel on FFM's. One of these days when I retire (this year) I will unlock the vault and try to cash them in. At least I won't have pressing matters and it won't upset us in the least if we encounter a situation like Mathpink.

I didn't really understand the problems that could happen when you book on FFM's as to standings on next available flights. Thanks to all who participated, especially craz.
