Well for the sake of the staff who wind up working for them (and iv a feeling it could be a load of ex Jetgreen/Jetmagic staff) I hope it works but the choice of SNN-DUB seems a bit futile! Aer Lingus never made it profitable and if/when the SNN stopover goes that will be EI's excuse to get off the route, then when Aer Arann went onto it with the better economics, they still couldnt make it profitable!!!
But best of luck to them anyway, will be watched with curiosity!
