I really agree with Ryan2000 and I am from Ennis. I used to use the airport twice per week up until January 2010 (but that is another story). My travels took me on alot of flights from Shannon to various destinations in Europe. I did meet alot of Cork people on those flights. It was not just the holiday maker but even the business traveller. One of my customers was temporarily transferred to Scotland for 6 months with his weekly flights paid for by his company (incidentally only 3km from Cork Airport). Cork airport had the same destination but the company saved money (including fuel travelling to Shannon) by opting for Ryanair from Shannon.
I would even say that the Girona flight was 60% full of Cork people anytime I was on it because it flew early morning and was cheaper than EI.
