It has to be said that unless there are any last minute changes, the offerings from Norwegian and Vueling this summer look pretty uninspiring considering that rather more was expected from both carriers.
Fortunately, there is decent growth from Ryanair and Easyjet. among the lo-cost airlines.
Not sure how Jet2 stacks up in terms of seats if there is no increase in based a/c, but we do have the A330 (I assume) and two or three new routes as I recall.
And not forgetting those BA flights - are any more routes expected from them?
