10 years in the A380 had been shown to fill a specific role in the market.
As the article (on the 10th anniversary) says, the best years are likely still ahead, as markets increase and airport slots are harder to get. Places like Heathrow will need A380 to transport the masses as extra runways are an even harder option.
The A380 is also loved by the SLF.
Smaller craft will be in the numbers game but I think the A380 will plod ahead filling a need.
