Probably the "RJ". It sort of defines the "Regional Jet"; we've got a slew of them.
Ridden the cockpit jump seat no them several times. Seems a very nice aircraft to operate. Somewhat power/altitude limited though and not especially fast for a jet.
Still, all airline managements are "hot" for these things. They were initially cheap to buy. IIRC, Comair got their first bunch for under 15 mil each. Now I hear they are in the 22 mil range. Usually flown by pilots at "entry level" in the industry so they can pay them low wages crap and get crews. (Son: Hey Mom! I'm an Airline Pilot now! F/O on an RJ! MOM: What do they pay you son? Well, $18K a year and I had to pay $18K for my training but NEXT year I'll make $18.5!) <--- Yeah, it's not that bad but it isn't real great.) And you'll notice management still charges the same for a ticket as they do for a flight on a "normal" jet
I don't think the comfort level in the back is anything the traveling public is going to fall madly in love with, however.
Still, RJ's are the "hot button" for the management lemmings and the phenom will have to run its course. RJ's have their uses and their limits. Right now, management has a hard time seeing the limits. Like when ours tried to run RJ's from Cincinnatti to Colorado Springs in the winter non-stop. Flight Ops told them it was too far but they flew for months stopping in KC to get gas.
