OK guys, not trying to be anal, but lets try to keep the terminology somewhat accurate so we know what we are talking about....
On the union newsletter you quoted "codeshare and/or marketing agreements".... that has nothing to do with a capacity purchase agreement under which most of the regionals are operating.
Also further down it mentions "Regional Jet (RJ) codeshare protections".... are you sure they don't really mean subcontracting of flying to an RJ operation???
