The positive is that as things are configured I can't see why BA would halt the FPP (at least this round) - they have nothing to lose!
The negative is linked to the above in so much as all the risk is loaded on the FPP 'successful applicant'. If you get through, have your eyes wide open - you've paid for their recruitment costs, you'll provide upfront financing for their training needs and ultimately if/when their business need changes (and it most certainly isn't improving), YOU will be holding the debt. Think wisely with your head and not your heart. Good luck to all.
