Amsterdam Schiphol is already a hub for easy, they don't have a permanent base overthere, but they are the 3rd operator out of Schiphol at this time. EZ
also flies to Orly currently (is even a temporary crew base, possible to become permanent)
The talks with the airports is, as far as I know, to attract NEW
destinations in the easyJet network. Don't know about Charleroi, it is EZ
policy not to fly to regional airports as Ryanair does, but to operate on the 'real' airports, so it would be Brussels Zaventem if they were interested in Brussels - which I doubt, Ryanair in Charleroi and Virgin Express in Brussels.
I reckon EZ
will try to get some destinations without interfering to much with Ryanair, yet. What about eastern Europe? I don't think there's a lot of competition on those routes for a low cost operator... Maybe a good idea to get easyJet known to that growing market, before they will know Ryanair...
