Having flown Ryanair a few times I shudder to think what they’ll do to Aer Lingus! If they are successful then they might operate two tiers – Ryanair will be the free-for-all that it always has been while Aer Lingus will be for the more discerning traveller.

O’Leary said that the two airlines would compete on the few routes they share, but that really won’t happen. It can’t. Shareholders will want the best return on their investment they can get and being competitive on price won’t do that.
