If Aer Lingus added to their fleet in Cork with an A319 this winter, they could put on an evening service to Paris making it finally into a viable hub from Cork like AMS and LHR.
In addition to that they could increase their frequencies on routes like Geneva and the Canaries etc.
It`s also possible that Aer Lingus Regional could base an extra aircraft from their forthcoming new deliveries of ATR 72-600`s in the coming year.
Just to be clear it would still be 3 aircraft, 2 320's and 1 319.
