abscond on your next Melbourne trip
Why would he want to go to Melbourne when he's from North America?
My advice mate? go and see the Fleet Managers, tell them your reasons, tell them you are leaving, tell them you are an honest person, tell them you want to repay the bond as that is what you signed up to do, that you are sticking to your side of the bargain. Arrange whatever finance you can in order to repay the bond and then go head held high and not looking over your shoulder for the rest of your career.
But that is what I would do. Moral issues aside, in the first world, a training bond is only enforceable if the skills acquired are transferable. For example, company A pays for your training, you sign a bond for $36K and you start working for them repaying your bond as you go. Company B then starts hiring people with the skills that Company A gave you, but at 30% more salary; then the training bond becomes a valid point. The fact that the Boeing or Airbus rating is on your nice shiny UAE gold ATPL is worth considering as the validity of our licence and its associated ratings, is worthless outside of the UAE. But then that is in the first world...
Good luck with whatever path you choose, maybe you could let us all know the outcome?
