cherrie,
as expected: QR has a binding contract... if you leave within the first year you have to reimburse certain expenses.
I don t know the exact amount, (ex-) QR crew can advise on this.
Mind you: same at EY (If u quit within 6 months)
there is some sense in it: some airlines have enough trouble with people doing the training and then running off to another airline for more money!
