I've been at Jet2 for some time now. I would honestly say to those of you who have been turned down.....think of it as a lucky escape!
The advice I have offered to my friends thinking of applying has been this: if you can afford by any means possible to wait for other companies to begin hiring then do so.
I completely understand what it's like trying to get a job (three years non stop letter writing to get my first airline position! ) but believe me when I say that leaping at the first offer can be a very expensive mistake that will take you years to recover from.
