Most airlines are not even filling their 747s at the moment so the A380 will only be a success in certain markets (like Singapore where the aviation market has grown exponentially). The A380 is the right aircraft in 10 or 15 years time when the industry will have grown considerably but it is not the correct aircraft for the present times - too big, too many unfilled seats.
The last I heard, the only airline benefiting from the A380 is Singapore Airlines while Qantas and Emirates are making losses on the A380s. Boeing got it perfect for the current market with the 787 and it shows in their order book.
BA 77.
