Second that^ CRJ’s are here for a long time to come. we still are taking New 900’s. (Yes replacing some older 200’s/700’s) but 60 NH’s alone in the CRJ every 2 weeks with no end in sight.. that being said. DEN ERJ is UA.. we don’t have anymore UA 175’s coming at the moment.. so i would go CRJ... Denver is supposed to be are largest Hub by summer....
