His average a380 incomes are out by quite a fair bit too. Put it this way, there are very very very few a380 captains earning more than $350k and there are very few a380 FO's earning more than $250k and there are very few a380 SO's earning more than $180k.
I'm still yet to meet an a380/744 FO on more than $250k or a SO on more than $180k.
I wonder if FBN has seen the a320, A330 and 777 contracts for China Southern and Hainan Airlines, these a330 captains are earning $250k net after tax and before allowances, bonuses etc. I don't think you will find any QF a380/744 captains earning that kind of money after tax.
Even the 777 captains at Virgin Australia have a base salary of around $286k which isn't very far off the QF 744 pay.
