You are correct, we don't have access to the accounts.
However, it is fact that passenger numbers on the DUB route exceeded those of the European routes. It is fact that fares on the DUB route were not lower than the European routes. Therefore if it lost money, it surely lost far less money than the European routes and contributed more to parking income, spend in the terminal and prestige.
It also seems to be the case that where EIR is up against competition elsewhere they are holding their own, probably helped by transatlantic connections.
