My older son runs an A320 Sim business. I have met a couple of groups of Jetstar cadets who have spent time in the sim prior to leaving for England for their A320 Type Ratings.
When the former cadets start at Jetstar they are on "flex contracts", which may mean fewer hours. Some buy time in the sim for extra A320 experience and to polish their skills and procedures.
Ah now I understand why you think the flex contracts at Jetstar are so well paid! The employment conditions at that sim make Jetstar look like the golden age of legacy conditions.
Back to my earlier post, I don't recall hearing any former Jetstar cadet here on PPRuNe complaining?
Because all cadets sign a social networking agreement when they join the course. It's a violation of contract. The Qantas Cadets were not even meant to post picture of themselves in uniform or aircraft pictures that identified the registration of their aircraft on social networks. Jetstars wasn't as strict but strict enough to discourage people from posting I'd say.
Also as I mentioned many people like their anonymity on here and there aren't that many cadets around. It doesn't take long to figure out who one might be if they did post. Again they may not want that to happen, particularly if they are bagging the course.
