I flew on a CRJ-700 for the first time 2 weeks ago to Guadalajara, nice plane for an RJ, but I was in FC! The 700's are leaving America West and more 900's are coming in. As for the 200, I hate the 'lawn dart', gotta fly on one for UA next month, then transfer to a nice EVA 747-400.
Great plane. Along with Flight Technique Analysis, I got a chance to completely dissect and learn how to program the 744's FMC and do an entire overview on the systems (the only thing lacking from a type rating course is we didn't have to worry about numbers).
The 900 is a sweet plane and the profitability is just amazing (26 pax to start turning a profit). Not bad for a ninety seat airplane.
