actually talking more to them they really just want to be sure to get on at all.

Since no seat assigment and all fare classes 0ed out on this itin, any suggestions on how to ensure they get a seat in Y?

If they get invol DB on this, any advice on what kind of compensation to expect? THey paid $1100 for each tix, so they should get hotel, F the next day, and at least $1100 in cash each right? Or if not, what?
