Yes I have compared the Jetstar V Qantas pilots wages
At Jetstar an FO on the 330 who absolutely pushes for all overtime will sometimes crack $200K as compared to the QF FO less flying and with a little overtime reaching $300K
The QF guys on the 330 are miles in front of the Jetstar guys on every metric wages, rosters, always having an SO tagging along, allowances etc etc etc
And really on forums such as this the QF guys have sneered at and taunted the Jetstar guys for a decade - telling them they are on "sh*t money" etc etc
