Agreed. I commute on a CRJ-200 frequently on a route which makes perfect sense. I commute GRR-DCA on a Pinnacle or Mesaba CRJ and it is an ideal plane for this thin route. The flight is almost never full but full enough to support the premium ticket prices it likely commands as a way for folks to bypass DTW and take a direct flight.

It's about 1:20-1:35 depending on direction of flight and winds. ERJ or CRJ would be perfect. I do question it's place though when I am launching from PHL-MCI in the dead of winter and looking at 2:45 or even 3:00 on the FMS and every single seat is full. That, folks, is a long flight on a 50-seater. Too long.
