Back to the original subject, it is probably accurate to say that the A380 is too large for most US airlines. Many of the major US airlines don't fly 747s for that matter.
But the A380 better succeed for my nephew's sake, here in the USA, who is building parts for it.
When United first configured their DC-10s there was a little lounge at the rear of coach. They laid out "party platters" back there so you could have a snack. How times have changed.
