You didn't mention which airport you would be flying from, which would make a difference to some extent. $600 pp though in the summer to Ireland is not all that bad actually. I think my ticket last June, Charlotte to Shannon, was a little over $600 and I shopped for months. At one time it was around $500 and I thought I could get something better if I waited and kept checking, but a better price never did come up. Prices just kept going up! Looking for good air deals during the summer is like a crap shoot, the chances of the dice rolling snake eyes are slim to none. Only other thing you may consider is finding a good fare to London and then taking Ryanair or some other budget airline to Ireland. It's work a look anyway if you have the time.
