Dublin is still important for FR even though MOL is not too keen to say so....
It is and always will be....also FR related they are being slowly squeesed out of Stockholm route from DUB. They have cut capacity a lot since Aer Lingus and SAS announced new route and increased flights. I got an e-mail two weeks before I was travling saying my FR flight was canceled due to low demand and I could be transfer to another flight or have a refund which I did and booked with EI and my flight from DUB was full and my return was upgraded to a A321 and was also full and they were cheeper than Ryanair. They have the lowest presance on the route this summer compared to 2011.
EI are expanding in areas that are not served by FR mainly and the regional accounts for a lot and they can compete with FR just fine.
