Ryanair mulls investing in Spanish airport operator, AENA - ch-aviation.com.
So if Ryanair did invest in AENA would Ryanair be more likely to base more aircraft at Luton? I wonder what motives Ryanair has in basing any aircraft at Luton after their cosy deal with Stansted seeing that their Dublin service could be based in Dublin leaving them with just a single Luton route.
I think that as far as Ryanair is concerned it doesn't really matter which airport is used as they often just shift routes between the two North London airports.
