I think a third ATR is definately possible, not sure it would be to DUB, BHD or the London airports, although I agree they would seem likely on the face of it. however LGW has never performed as well as I would have expected for EI, switching to an ATR or to SEN may help, but the overlap between SEN and STN may be too great for Cork? Other destinations mentioned by Mr Muller were specifically EMA (being launched by Ryanair in a few weeks) and Leeds/Bradford, I guess Aberdeen might be another reasonable route, but probably not daily. After that obvious destinations are a bit thin on the ground, maybe Cardiff, perhaps Southampton/Plymouth/Exeter? I think most of these have been tried in the fairly recent past by one airline or another, some more than once. Maybe the EI/RE partnership can alter the dynamics a bit.
