Whilst there is a lot of speculation going on here, I can't for the life of me understand why the Jetstar pilots aren't willing to say "Excuse me Dixon, Borghetti, Joyce, but Qantas mainline pilots are paid $X00,000 to fly an A330, why can't we get the same amount if the aircraft is in Jetstar colours?"
Can any Jetstar pilot answer that question? Why on earth would you be willing to sell yourself short for essentially the same job?
When will they realise that low cost does not have to mean low salaries?
