Is there any difference between the experience of flying a 747-400 as a passenger compared to a 747-100 or 747-200? What I thought was strange about the 747 classics was how much the wings bend up and down during flight. It's a little unnerving the first time you see it. I never got to fly on a 747SP, but I did see one at HNL in 1978.
We're probably going to try to sit as far aft as possible (honeymooners, you know) . . . so I'll keep an eye out for that wingflex.
I should point out that I've never flown any 747 configuration, just some 737s and a pair of 767s.
The 747SP is a rocket! I changed a whole vacation around just to ride on one! I had a ticket from Johannesburg to Miami, and I asked them if I could exchange it for Johannesbug to Frankfurt. My only flight on the SP.
As for the 100, I think I only flew it once on TWA, and we had 4 -200's. Only did the 300 once LA to Amsterdam round trip.
The 400 is great, I've been on combis and regular. Been upper deck in coach and all over the plane, its like a big flying house.
400 has better TV and audio and all that. Lots of 200's are gone, damn few flying. Wings do flex, that is what they are supposed to do.
