Re: CORK
We have to be wary of the notion that Aer Lingus have some kind of duty to provide transatlantic services from Cork. Even though, they are government owned, they are still a commercial organisation and from their perspective will only consider it if it is to be profitable.
As regards the range of an A319. The distance to Boston would be 1,000 NM under it's stated range; the distance to New York would be 800NM under. Destinations in the North-East of the US shouldn't be an issue for range; profitability, the technical issues decribed by Handover and the lack of ETOPS certification would seem to be stinking points.
