There is at least one Airbus where the deck slopes upward toward the
tail at the rear of the fuselage, where it begins to taper. Most of
the cabin has a level deck. I don't know the model; I just noticed it
one boring day at Heathrow. I assume this is to keep the passengers
sitting at the widest part of the fuselage as it tapers upward. For the 
same reason, I would bet that the deck follows the C/L of the tube 
pretty closely; otherwise cabin space would be lost.
