I think it's likely that both British Airways and Japan Airlines--already large 747-400 operators...

I get to fly a BA 747-400 in June (first time) and I'm as excited as a little school boy.

Try to get a first class or business seat if you can afford it, economy class is horrible in any large airplane no matter what company builds it.
I flew in 7 747's and I loved it, but, the seats bothered my back and behind, so try to get a comfortable seat if you can.
It was so neat to watch the wing's flaps in operation, and when your on the ground the wing is straight, but, in cruising altitude the wing bends up , don't worry, it's normal, and planes are engineered and tested beyond what the FAA requires for wing flex, ever see Boeing test wing flex ? it's so cool to watch the wing snap when flexed way beyond it's normal complicity.

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.
