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.

Yes, I've seen simulations of the wing flex on PBS/Discovery/NatlGeographic, but never in reality. I am going to insist on a window seat and we will hopefully be far aft.

Sorry for us, we have to fly coach. More's the pity, we have a layover at LHR before getting on a ScareBus something or other.
