smile. nail, head.

if they make you move, you should be able to get your original seat back. the GA i dealt with didn't want to make the passenger move. but, in effect, that was what they did to me so why shouldn't the person that got my coach seat have it done to him.

in the end, i accepted $100 but CO should have some type of service recovery kit like other airlines (although i am a bit confused by the moniker "service recovery." it's more of a "goodwill" kit.).
