EMA, being an ex Go base, is all, or predominately -300s. easyJet have been training new entrants on the -700 so it's inlikely that EMA would be an option for at least your first 6 months.
BFS is supposed to be full. I would say that LPL was a strong possibility, though.
There is a base transfer scheme which claims to work favourably, but it does rely on places being available at your preferred base, of course.
Newcastle is the latest base; no idea how numbers are stacking up for that one, though.
