I was thinking of a configuragion like the CO ERJ-135/ ERJ-145 which is or can be a 1-2 seat configuration rows (A and BC) - these are also 14/19 row aircraft. The YX Dornier 328 configuration is the same FWIW. This obviously would allow wider seats and would especially be more comfortable for those seated in row A because you would not be crammed in shoulder to shoulder as you often are in the CRJ-200s. Needless to say all the seats in such a 1-2 seat per row configuration should be a couple of inches wider and the aisle could be wider as well.

Once a woman who honestly did not weigh more than 100 # got on a CRJ-200and sat beside me and exclaimed "These seats were made for children." I thought she pretty well nailed it. I am about 5' 9" and under 145 # - i.e. even two smaller people felt cramped seated beside each other.

As far as I can tell, UA and of course AC and NW are the only North American airlines that fly the CRJ-135/145s.
