It's a sad fact that few people these days seem to move up the ranks on to jets. You either get straight on to a jet or your stuck turbopropping for a long time.
I've seen this turn on it's head this year, the turbo-prop outfit I fly with has lost dozens of people to big jet operators, the industry seems to have turned on it's head.
Good times to move up the ranks, just make sure you're in a seat you're happy with when the music stops!
