Personally, I'd opt for the ERJ. The pay is the same for FO's. We have over 200 ERJs and less than 50 CRJs. Once you bid a jet FO position you can't bid the other jet in most cases, unless displaced. Long term, there will be more lines and trips to trade with if you are on the ERJ in ORD. You may spend a little longer on reserve in the ERJ, but not long as we will hire 300 in 2011. No matter where your life takes you, you would be able to commute to the corners of the US if you bid the ERJ. Eagle seems to be unsure about the utilization of the CRJ fleet. DFW, ORD, NYC, it's all up in the air right now. You don't want to be chasing equipment while junior. Hope this helps, remember it's just how I see it. Get some more advice before choosing.
