Unless you want to be based out of DEN. COS, or perhaps PHX, the CRJ is nearly gone on the West Coast. Delta is down to only 4 CRJs out of SLC and you'll never hold it. LAX, SFO, and PSP are basically done as CRJ domilciles with only minimal staffing now. The American flying with 700s out of PHX, DFW, and ORD seem safe from not disspearing soon. Fifteen new ERJs are going to replace current UA 700s in a year or so. I don't know how many we fly for them right now.
I'd really push for getting the ERJ as well. They haven't been doing transitions from either airplane for most of this year as well. Probably won't for a while either. They'll be no hired into the CRJ and transition into the ERJ a little down the road.
