[Yo-Yo]

Worst seat in the air is a 737-200, coach, configured for short haul, with fixed arm rests.

Next is the 757 short haul.

The CRJs can be punishing, but they also add the insult of a HARD seat bottom.

You can't make blanket assertions about aircraft types. All interiors are specified by the airline buying the aircraft, not by the aircraft manufacturer. So one airline's 737-200 can be very different from another arline's 737-200.

You gotta name names!

OK ...

Delta, United, American, USAIR (been a while), continental/United.

You are right - not all airlines fly the same seat config. But, I have yet to encounter a 737-200 with wider seats.
