I also think that the DAA will have to be realistic about Cork's status among the airlines of Europe. They will not pay premium rates to land or park there so it's important that incentives and charges are competitive and that costs are kept under control.
The DAA have been playing hardball with Ryanair in relation to Cork for almost 15 years now and they're not winning. They might as well accept that they'll have to give them a generous package if they want to achieve serious growth.
Let the same offer be made to Aerlingus and any one else that's interested.
Having said that the decision to grant Shannon debt free status has seriously undermined Cork and has allowed Ryanair to withdraw from one of the airports and get incentives at the other for the same route something that was never possible when both airports were under Aer Rianta and the DAA.
Maybe it'd be worth asking Wizz to return to Cork now that Ryanair have withdrawn from 3 their former routes.
