QF have been running a cadetship for over ten years so it's hardly a Jetstar thing.
Lol. Closer to 20 years. First course started in early 1990. A hiatus between the end of '92 and about '97 and then it went for about ten years. I think it's in hiatus again. Given the lack of recruiting in mainline I suspect that hiatus will be a long one indeed.
Many of the graduates of those early '90s courses are now 767 and 737 Captains.
