....some people here seem to think QF should be running multiple flights from every city everyday.
Historically more than 50 per cent of the origin of passengers on say Oz - SIN and Oz - HKG plus quite a few other destinations including the USA has been Oz not foreign ports, because Australia used to have more of us going overseas than foreigners coming here. We still exceed overseas visitors, but obviously not on every route - mainland China is one set of routes where there are now more foreigners coming here than us going there.
As a small example, at least twice as many Australians still visit Canada annually than Canadians visit here.
So from this, if CX and SQ can run multiple departures from their home ports into Oz each day, but QF has far fewer seats (and typically - crucially - fewer flight frequencies) - than its major foreign competitors (including TZ v JQ and other similar comparisons), why?
High, unionised unrealistic Australian wage and salary rates might be one reason, our high costs as a nation might be another, but overall, sadly for QF, it's been unsuccessful compared with its foreign peers. It doesn't even fly to KUL, and its list of abandoned destinations could fill a small book (although admittedly markets and demand change over the years.)
60 per cent plus of the total market of international travellers into and out of Oz flies with an airline other than QF, JQ or EK, and including EK is generous because QF does not get every cent in revenue from the total passengers on EK.
