To add my 2 cents, I think we'll see an overall reduction in CRJs in the Delta system.
Eagle flying is possible, but I wouldn't expect a significant number of airframes. After all, how are we able to compete with the cost structure of places like Republic and GoJet? Not one airline could staff all the Eagle flying that will put out to bid, and that is why we will probably see a piece of it. I wouldn't expect new airframes either. If there is, it could be a while before we see that get into motion, we would definitely need a new contract first. In fact, the company has said at least once that they want a contract before bidding on Eagle flying.
The attrition on the CRJ side is slow. In fact, they have only lost 20 guys in the last 6 months! ERJ side has seen triple that. However, most are FO's that are leaving, 58% to be exact.
What this means is, while we upgraded a lot during the summer, upgrades will be slow into the future since Captains are not seeing a lot of movement. Frankly, there are not a lot of places to go to right now.
