I need to put a bit more clarity on why i started this thread.
The A380 freighter is not a problem Fedex are buying and will provide the ground infrastructure, which is probably there already.
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.
If most flights into the USA are on 747, 340,777,330, 767, 757 etc. which will land and dock at a gate so passengers are disembarked in less than 20 minutes why should the American airports provide similar facilities for the A380 when it will only be used by airlines who are in opposition to American interests. 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?
This is the point I was trying to make....
