I wonder where P2F comes into it here. The primary complaint was about foreign pilots working during winter in Canada, mainly German ones apparently. Well, those are certainly not P2F pilots as those German carriers that take part in that program do not offer P2F in the first place. Pilots are hired based on entry selection and given the type rating against a 12 month deprecating bond. Or they are airline cadets trained from the get-go for their airlines in a program where the airline carries a substantial part of the cost. Unlike in Canada those pilots get their first jet job usually with either 80 (i believe non of the MPL guys went to canada yet) or 250 hours and their experience is mainly on type, in general between 4000 and 25000 hours.
By the way, in which way is the 737 rating broken into parts over there? Here in Europe it is two parts, -100/-200 and the rest rolled into one.
