How does Jetstar make a profit from Cadets?
Money for training goes to OAA/CAE/Swinburne, not Jetstar.
The 30-odd grand for an A320 type rating goes to CAE/OAA in the UK.
I've met Jetstar cadets from four or five courses, and from what I can tell about 90% complete the training and I haven't heard of one to completed not getting a job.
The former cadets now flying for Jetstar regularly complain about OAA/Swinburne being a bit disorganised, but seem generally happy with the deal they got.
If you were a young guy keen on the airlines and got offered a similar cadetship you'd be mad not to jump at the opportunity.
