To me, self funding is you paying for it all with no remuneration for the training. The whole point of CTC's financial plan is that the airline pays back £1000 per month tax free for training costs incurred...
Why question was whether they were scrapping the unsecured loan, making it all or part secured but still having the airline pay back the agreed money directly to the loan owner (therefore not strictly self-funded because the airline is paying for some of it) or whether they are making it self funded and the partner airline won't pay any training costs.
Big difference in cost.
