I have been preaching how the A380 would be a flop for years now. Airbus has slightly over 160 firm orders, but 43 of those orders come from one airline (Emirates). They are the key. If Emirates dumps its order, the A380 program will be dead. Done. Stick a fork in it. Also, a cancellation of their order by any of the numerous airlines that are "considering all options" could lead to a domino effect that will cause many airlines to follow suit.
