FR/EI
Ryanair will surely get their hands on Aer Lingus eventually... ... could be the start of serious transatlantic low fares.
I wouldn't count on it. Firstly the EU competition authority have blocked it, but even if they did get approval, the Irish Government and the Aer Lingus workers are totally against it and together with Denis O'Brien (who is totally against the takeover after MOL ran a Ryanair ad mocking him) they hold about 45% of the shares meaning that the max Ryanair could get would be 55%. With only a simple majority they couldn't pass any special resolutions meaning they couldn't merge the airlines, sell the Heathrow slots or make any major fleet decisions. The proposed EI/FR merger is definitely a dead duck.
