Flybe, from my experience, are an excellent employer. As has been mentioned 'a great first job' but also alot more. Since the transformation into Flybe in 2002 where they were on the verge of going under as Jersey European they have come along way. 80 odd airframes - not too bad and I expect that to grow in the near future with rumours surfacing of further mergers (baby, bmi regional, who knows). With the downturn and silly fuel prices flying the Q4 and the 118 seat 195 I think they will fare better than most.
Getting your first job is the biggest hurdle but once you've got it you are still at the bottom of the seniority list, and at risk cause if things go tits up you are the first to go. I believe that for the foreseeable future, as new starters, you are alot safer at flybe than at the likes of easy, jet2, ryan etc.
