What I am saying is that airlines have to make money to survive and the reality is that Shannon does not attract enough passangers.If not enough passangers buy tickets, then the airlines pull out and move elsewhere.This applies to Aer Lingus, Ryanair,Delta and Continental.So if the people of the area want to keep their air services then buy a ticket.
I believe that Cork makes money for Aer Lingus so they will stay.Its not rocket science and its not personnal its just economics.
