2012 is irrelevant. What is concerning now at the huge loss of routes over the last few months at DSA. Whatever the reason, it hardly gives confidence for the future of the airport to operate passenger services.
The airport haven't managed to replace any of the lost FlyBe or Wizz routes. Ask yourself why.
Yet all they talk about is their huge growth etc etc. That will look pretty stupid, when they are back down to 600k passengers again.
