hey!
Long haul out of ireland is vertually non exsistent!! EI as you know are a mix. Its a pity that Ireland hasnt got a long haul only airline like virgin. But with a population of only 4 and a half million theres only so much you can do. Airlines like XL and first choice do the odd charter but even though they have local crew during the summer i dont think they use them as they are only one one type of aircraft.
Truth is if you want only long haul you'll have to go to london or commute. A lot of people commute. I know crew who live in ireland and work for AIr NZ, Virgin, BA, United..... and they commute. But they have very little time off and the cost of flights mean you can really settle down.
