Jet2 'up norf' do a very good Pilot Apprentice scheme! Also they employ seasonal folk in ground positions by the coach load, have a look at what's on offer for Summer 2015!
Do not rule out focusing on the turbo-prop operators, it's the best way to set your career up with all the right skills...and far more fun than managing big boring jets in straight lines for hours on end!
Which I have to go and do now!
Good luck!
