The reality is that if you want the best possible chance of getting into an airline go with CTC. This year they have placed cadets at Easyjet(flexi crew),Monarch(permanent), Qatar Airways(permanent), Jetstar Pacific(Vietnam) in recent years(permanent),9 cadets with Thomson although I believe they will be doing their own thing from now on, Cathay Pacific 2nd officers(permanent) BA (future pilot program), and in recent years have had links with Jet2 and Flybe.
And before people jump down my neck I'm not associated with CTC.
Like it or not they are your best chance of getting into an airline provided you have decent training files and are eventually placed into their hold pool.
Ryanair take a lot of guys from Oxford but no official affiliation as far as I am aware. April 1st no more interviews for cadets(see website).
