If the A380 has to land, taxi to a stand, and offload by steps and busses meaning some passengers may take more than an hour to disembark, unless the costs of flying to America on the A380 is much less than on the other aircraft, why bother?
Americans allways find a way to make things harder for the outsiders; Before it was the noise of the Concorde, now its the size of the 3-eighty.
My worries are that no American airline has bought the passenger version and is hardly likely to in the near future, therefore the Americans have no national urgency to provide the ground infrastructure required for the aircraft.
I agree with that. If they're smart they will not spend what they don't have. Thankfuly the rest of the world is very much interested on the new machine.
Americans could make a commercial double deck version of the C-5 Galaxy, couldn't they? just change the engines, and they'll be in the game.
