Sorry EGDR I keep confusing you. My point was that rather than spend £50,000 on an integrated course, I would suggest the £30,000 modular route, £5,000 on FI Rating and then you'd have £15,000 to top up your FI wage (around £10,000 - £12,000).
However you don't have to bother with an instructor rating, you could stay in your current job and keep applying for airline jobs but this is likely to take quite a long time before you get one.
