It is simple really...A true regional should ONLY operate PROPs...seating size doesnt matter because they will still be a hell of a lot more efficient yet slower. So if they carry 120 pax on the new Dash 888...they wouldnt take it too far simply because it wouldnt be fast enough. 300 kts is fast but still not fast enough. They may take 120 people from Dallas to St. Louis. A route a jet just is not meant to do. All jets should be at the majors/legacies. The idea of a "regional jet" is the most retarded thing I have ever heard of. Of course it would be a lot nicer if there were no regionals or majors. It would be nice if the career path was you get on with an airline start off on the little beech 1900s and in 15 years you are a captain on a 747.
