Fuel for the "my plane is better" fire:

The E-170/175/190 has wider coach seats than any aircraft at USAirways mainline, and the seat pitch is equal to or exceeds that of any USAirways mainline aircraft. I didn't bother to check every mainline carrier, but the larger embraers seem to have bigger seats than most every plane in Domestic mainline fleets, save for some 777 operators.

Don't worry, my SJS hard-on soon went away when I saw that the widest coach seats available on any USAirways aircraft were on the mighty Beech 1900!
