It's fascinating that we are still considering the re-mortgaging of parent's homes as "sponsorship" by the wonderfully magnanimous and fiscally cunning airlines. REAL sponsorship entails a wee bit of risk and investment by the airline, and a then virtually guaranteed loyalty and commitment by the recipients. Back in the "when we "days of real airlines with Flight Ops and Flight Taining Departments led by REAL pilots and not KPI MBAs, selection was the key....the right cadet! A good Cadet made a good Second Officer made a good First Officer made a good Commander made a good etc....! From Cadet to Chief Pilot. Quality, not the ability to pay was the key. Selection based on suitability and merit, not bank balance.
