OK. So they would need to make a major investment in a base at an airport dominated by EZY. I wonder if they'd change their minds if EZY decide to reduce or withdraw their own base? Maybe they feel the south eastern holiday airline market is saturated already.
I still think SEN would be well advised to talk to continental carriers, offering them a rapid transit London gateway. No doubt they already have, but I hope the contact is ongoing and persuasive.....
