BFS, LTN and NCL will go Airbus when the Boeing 737-700 leases run out or they can sell them on. Another 2-3 years I would expect.
As for social life at easyjet - life is what you make it. If nothing is happening at your base organise something. Whether it's a curry night, pub night or whatever.
At my old small base we might only get 6 people turning up for a curry but better than nothing.....
