Way I did it was as follows,
First Job after Cpl/Ir, Flying A320 round Europe Major Apts.
-Company Sponsored MCC & A320 TR
-Couple of Obs Flights
-First 30 sectors Training Cpt & Safety Pilot Followed By Route Check
-120 sectors with training Cpt Only then final route check, to fly with normal line Cpts.
All Sectors are Rev Flights
About 28 Sectors a month appx 72 hours
Training is great; Already flew into most Major EU apts a couple of times. Looking forward to the Charter ones now
