EK are busy taking market share, and flying around with very full aircraft. They have from a business perspective, found the right balance between the hub and spoke model, and being able to connect any two points on the globe that are currently worth going too in terms of revenue.
The future is all about access to new markets...just listen to the frightened noises made by the Canadians regarding EK's entry there, or the pointed words from the KLM/Air France chairman.
There is ample potential to fill all those 380's and 777's, the problem will be getting into the markets so it can happen.
If it all goes pear-shaped..orders will get binned.
