Rav,
Honest question, are you comfortable whith the level of experience of a cadet that has only flown for CX that now has 8 -10 years of experience?
Would you pax on a flight captained by the same (ex) cadet?
I too would prefer new joiners whith more experience but it's not up to me, and I also agree that an airliner might not be the right place for them to get that experience but Rav, how else are they going to get it?
