Back before deregulation I once flew on a United 747 from Chicago to Seattle as one of 17 passengers. After we were up and cruising the flight attendants set up a self service bar in the back of the main cabin and then they all disappeared upstairs for the rest of the flight until landing. I had fun checking out seat positions from the most forward where you almost felt in the cockpit to the most rearward where you could see the twisting of the fuselage when the plane banked. The tail clearly banked a split second after the wings.
