apply for MAM-its a Qantas Shorthaul flight attendant position. You will work 80 per month minimum but will probably work way over that. You will fly all over Australia and Asia. The money is great. What I'm trying to say is, keep your options open, as Jetstar isn't your only ticket into the airline industry. Obviously there are people around that work for MAM who are are bitter and twisted about not having a "fulltime" position as such, and not being eligible for staff travel, but I have really enjoyed my time there. If you are interested go to the website and apply there.

Good luck with your flying career!
