AFA, I think you're mis-interpreting the logic. You're not signing over anything even if the bond is £100k so why would you sign over your first born and house? Yes plans change etc, but you can say that about anything, like why pay Ryanair £30k for a type rating to then realise it's not what you thought it was, or why pay £120k for flight training to only realise the job isn't what it cracked up to be. Yes I agree it's pretty disgraceful making a type rated bod sign an £18k bond but there are choices in life, and those choices are either don't join, call them up and ask exactly why the bond needs signing and what is it for exactly or just get on with it.
