I don't think its heavily lossmaking!
I disagree. Looking at the prices of tickets this route is hemorrhaging reserve dosh from Ryanair's coffers.
I think when Ryanair concretely see how using their Cork based aircraft this summer to do a couple of Carcassonne rotations has been hugely profitable, and then compare it to the gigantic losses being made on the Dublin route, they'll finally realise that the aircraft can earn them millions (on routes such as Bergamo, Hahn, Budapest, Madrid, Palma, Charleroi, Riga, Krakow, Warsaw, Treviso, Beauvais) instead of losing them millions on Dublin.
