Obviously this new-fangled idea of getting pilots to do degrees and diplomas to make them more commercially and organisationally savvy has fallen well short of that grand ideal!
Pilots are still pilots, and although some think they have a grasp of high finance and can solve all of Dixons/Strongs/Eddingtons/add executive name here/ difficulties, truth is that many would struggle running a corner shop.
Frinstance, anybody BOTHERED to go to the airservices page on enroute charges? Kym, me lad, ever pointed the mouse in that direction? Try comparing the enroute charges alone for a standard gross weight B717 against a 146-100 BNE-MKY. Just try it, my lad! Aha, one discovers that heavier MTOW aircraft get slugged more money by AsA every time they fly the route! Next, try looking up landing charges. Then look at leases. How about cost of spares and rotables, and a place to put them. Etc Etc.
Maybe the 717 is a better performer than a D8-400/146/F100 on a number of key routes. But any similarity between the outcomes of QF management actions v the predictions of tossers like young Kym will be purely coincidental, and about as reliable as investment decisions guided by Anastasia the Gypsy Mystic and her crystal ball (ref: Picture magazine classifieds, right after home girls).
Why do you insist on wasting perfectly good electrons by posting such drivel, kid?
