I was on 727’s, once on a 707 (what a bird), and I think even once on a DC-8.
And my favorite, the Lockheed L-1011 Tristar. A few times.
During my Air Force days, I remember boarding a Delta flight in Atlanta for a (relatively) short hop to Dallas, and discovering my aircraft was an L-1011. Of course, the ATL-DFW segment was the first leg of a flight that continued to LAX, as I recall. Nice flight, albeit short, on a very underrated wide body jet.
I flew an L-1011 a couple of times years ago. . . massive plane. Hard to tell you were moving sometimes. It was very impressive.
