The only way the MPL will succeed is if airlines start paying for their pilot training again instead of relying on desperate 'self-improvers' or poaching pilots from other airlines.....
Beagle has, quite rightly in my opinion, focussed on the crux of this issue. Airlines should be much more proactive about where their new pilots are coming from, selecting and training same. As one who was originally sponsored (back in 1970 - with an agreement to pay £,1000, would you believe, back over the first 5 years of employment) I am quite appalled at the level of debt which our new pilots are encumbered with to enter our profession. But that's the way the world is at the moment - "too many worker drones in the collective".
As an aside the original meaning of the word "mortgage" means "debt until death"!. It seems many these days are indeed mortgaged until death - where's the freedom in that?
