The bulk of Shannon’s growth was in the two years post separation, while growth in recent years has been weak compared to DAA airports.
The DAA has a fine line to tread with Cork. Too little growth and there will be calls for separation. Too much growth and It will be said that Cork could stand alone. Of course, it also depends on the attitude of the DAA. Is Cork perceived as a financial drain that they would happily lose or is it a defensive asset that allows them to keep Shannon in check?
