My two cents,
I think Delta pilots are going to have a tough time getting a competitive cost structure for a CRJ-900. Sure, it would be nice to have them, but, at the same time I want to see the mainline recover. I still have 25 years left in this industry and I'm not planning on retiring at ASA. I think the aircraft itself will be a huge boost to the passenger. Granted, I know it is a tighter squeeze than that overgrown jungle jet. That tighter sqeeze also equates to faster speeds at lower fuel burns while carrying the same load.
Since we are talking about the CRJ-900, lets talk about costs outside of pilot pay. First off, the 900 and the 700 are almost identical in systems. The 900 has a different pack, but it operates the same from a pilot perspective. ASA has a simulator on property (100% leased at FSI), trained IP's, trained mechanics, and trained pilots (I can't imagine more than a day of SOE for the 700 pilots). We have a parts inventory and are currently replacing existing 700 engines with 900 engines(no new thrust, just lower temps. Hoping to increase life). I think you will find that the CASM is quite good on the 705, and much better than the EMB-175. It is difficult to analyze how the revenue potential for having first class plays into it. As with the mainline, I would bet most seats will go to mediallion upgrades. Passenger moral will improve dramatically. Thats worth something.
Let me reiterate, I want to be a Delta Pilot someday. But, unless the plan is to operate 200 of these jets, ASA is in a position to operate these aircraft with lower costs and almost no start-up costs. Maybe the line in the sand should be drawn at anything bigger. The CL-65 has no additional size potential.
pup out.
