This is my experience with a career success rate.
Every person I know that has been motivated, hardworking, ambitious and busted their butt has gotten anywhere from a decent to excellent pilot job. I have noticed a direct correlation between motivation and where people end up.
When I started at the commuters, we had 9 of us in our new hire class. This was 9 years ago. One guy washed out. I don't know what ever happened to him. Here is where the others are:
Three at AirTran.
One at JetBlue.
One at Southwest.
One is a sim instructor for Flight Safety (I don't know how great of a job this is but he seems to like it).
One is at UPS.
Shoot. I can't remember the last guy but I know he is at a somewhat decent airline.
