This really would be a great deal, I think. It would give EI the stability it needs to continue operations aswell as using MOL's well known talent for profit making. Ryanair would almost certainly benefit in uses of the terminal etc. etc. I see no reason why MOL would get rid of the EI logo and colours as it is such a strong brand name. But i really can't see Aer Lingus the low fares airline....
