OK, let's try to get my list in here ...

Never got to fly them, but I rode jumpseat in the B727, B737 (100, 200, 300, 500, 700), B757, DC-9, DC-10, MD-80, and ATR-42 back in my Continental days.
Interesting 737 jumpseat story ... one of Continental's (now-retired) antique 737-100s was an airplane that was delivered new to Lufthansa. It was subsequently sold to PeoplExpress and added to the Continental fleet during the "Big Bang". During it's Lufthansa days, the airplane was hijacked by a gunman who, in the course of the hijacking, shot several holes in the airplane. The FOs said that on the walkaround, you could see the fuselage patches where the bullet holes were repaired before the airplane was returned to service. (That story was told to me on the jumpseat of the very same airplane on an early morning ATL-IAH trip.) Interesting ...
