Well I am not sure how gaining a CPL/IR & having a pass in year 12 qualifies someone to know anything at all about business or financial matters.
The reality is that if the QF pilots had real expertise & skills in airline management this fact would have been identified & they would have been hired by airline boards all around the world to run their airlines. As we know not one QF pilot has been hired to run an airline anywhere , but my goodness they talk a big game.
Check the average wages of QF V CX cabin crew & you have your answer right there, then tip in the weekly wages of the Sydney Glamour Boy (A380 Second Officer), & you are easily over $20k crew cost differential per service.
