Amazing isn't it - three years ago you would probably have gone anywhere and flown anything for a first job, and a dash 300 at British European based on your own rock must have seemed like manna from heaven.
15k bond - so what. If you don't leave you don't pay, so the only ones who it effects are the ones who want flybe to pay for a type rating so they can sod off and leave the company in the lurch (and their ex colleagues who will sufferfrom even more roster turbulence whilst replacement crews are hired). Hence the bond in the first place.
That said, best of luck with your new employer - presumably no bond, no roster changes, nothing but really green grass.
(And from my side at least a shame we never got to fly together)
