If you are looking for clues, then take a look at the recent British Airways FPP (cadet) scheme. Who are they utilising for their source cadets? Are they the same FTO's that other major airlines use as integral partners, and resource for their cadets?
One of the suggested FTO's offer modular training. Could this route, which is cheaper, be feasible? Or is the 'modular' bit less advantageous?
