With Brexit in mind I expect to see those 3 E195 in Aer Lingus colours and all being based in Dublin with one being used for SEN. They can operate some smaller European routes with it.
And for the ATRs they need a British airline that uses them as a wetlease from SEN. No more Flybe it seems, so why not as Easyjet... not likely to happen, but would be a better channel to sell tickets on European routes than Flybe which is hardly known on the continent.
