That may be the case but in that case the point is that the deal was sub economic and the airport couldn't survive without State Aid which has distorted the market place.
The airport more or less broke even in 2007/08, when they were handling just under 2.5m passengers, and 30,000 tonnes of freight.
They either need to get back to this level, cut costs, or increase the revenue they gain from each passenger.
Unfortunately, those passenger numbers look unlikely, and Ryanair will fight hard to avoid raises in fees, so its down to growing cargo and cutting costs.
