Sadly, I have no status. I was SO CLOSE last year to being Delta Silver (which isn't much, but for someone who doesn't fly often, it was still close). Presuming I'm dressed properly and am polite, is this something I can ask for when checking in?
To the tune of:
"Is this flight very full? I'd be happy to volunteer my seat if I could fly out later today in Prestige/First class."
Or is that too forward? Or do I wait until I'm at the gate and they actually make the call?
