Yes dudly my point has always been that there may not be a big enough market for, "several hundred" aircraft, Bahrainlads mention of, "one or two arriving early morning" may be a bit nearer the mark, in which case Airbus won't break even. Aircraft the size of the B777 or Airbus 330 seem to be the current favourites.
Of JFK, LAX, ORD, SFO which ones have plans to cater specifically for the A380?
