Like fishu, I can't see why this is being argued about, except that I do get a bit peeved when people say A380 can't succeed if it won't appeal to USA based airlines. ^
My view is that it will work well - for those airlines who have chosen it on the routes where they intend to operate it. When people are about to make a journey of 8000+ miles or 14000km lasting 15 hours, they're not thinking
"Now, shall I get the 9am flight or would I be better waiting for the 9:45am flight?" It's also going to help out here at LHR, where runway slots are saturated. That's why one in eight movements at LHR will be an A380 by 2016, and that does not surprise me in the least. Why send 10 planes to the same city when the job can be done with 5 A380s?
Someone posted the list of airlines who had placed orders, and not surprisingly, those based in Australia and Asia featured prominently. I have no doubt that they have done their market research, and will be able to fill every seat.
So who cares if a USA airline is going to make more money with a 7*7 in an entirely different market, half way around the world? Good luck to 'em. I don't see the need for a "mine is bigger than yours" pissing contest.
