Racedo is correct on the PSO issue. Governments cannot subsidise routes which are being flown commercially. Given the two different schedules mentioned, the Kerry to Dublin business trips are facilitated, which are the main market. In any event, after our budget in December, I don't think there will be any PSO servies in Ireland apart from (possibly) a Derry - Dub - Donegal - Dub - Derry type rotation. Kerry / Shannnon / Galway now have motorway links which mean centre-centre journeys are faster than air; Sligo rail services have been vastly improved, and NOC is in the middle of nowhere with no large city nearby. And the government is broke (bonds now at around 6.8% and rising).
Oh, and to the poster who suggested RYR are upsetting the Irish govt over Belfast City, I think not - it is in a different country!
