I'm not sure I understand this. This thread is about the mention of the Colgan crash and codeshare airlines from the Magenta Line. EVERY airline codeshares with a regional partner. Some more than others. Some with EMB-170/190's. CAL only allows 50 seat jets. I'd say that's good. The only better you could do is all CAL flying is done by CAL pilots. I'm all for that, but I don't expect that to happen.
