I been out of the loop since I have left a DC, so forgive me for asking but is ComAir still around? Last I heard, they were slowly downsizing it and giving aircraft over Pinnacle, SkyWest and ASA...

As for the DCI movement, It would not surprise me to see SkyWest back east again and like wise with ASA coming back west and bringing Pinnacle over to the west once all the Mesba CRJs are moved over. Having worked both at Delta and Skywest - It's typically Delta having their way with the DCI flying where they want and when they want it. But keep this in mind with the slots, it will really come down to what airlines get what slots out of LGA and DCA. I know Allegiant is looking at the LGA slots along with Southwest - so if they get slots, Delta may end up keeping the LGA/DCA flights to mainline Delta, at least on long haul flying.
