So when a CRJ CA can no longer hold CA and is now a CRJ FO, that's not being displaced? When LGA closed, CAs were displaced back to the right seat in ATL. When ATL closed, people were displaced to the right seat in DFW and so on.

Your attitude suggests you were burned hard one day. This is no ones fault but yours. You can keep being angry and bitter about it but if this is how you treat others on the line, you have been a large part of the problem. So glad people like you do make up the majority.
