Agree to all the above.
As well, whenever I offer to take a bump (and I do whenever I can..usually on the trip home as I can't chance it on a business trip out) I ask if this means I will lose the seat I already have. They always say, no. I ask, even though I alreadt know this. Can't hurt to re-inforce it! Being an elite, I usually have an F or a coach aisle emergency-row exit reserved so I REALLY don't want to give those up.
I have never gotten changed to a crappy seat when I didn't get bumped. Actually, the last times I have taken a bump I was put in F on carriers where I didn't even staus!
YES!
