First time poster to this thread. Did a quick search and didn't find anything on the topic.
On flights for 26-Dec, SYD->ADL, on ITA Matrix, it only lists QF flights at the 'Flexi Saver' price, even when I select 'Cheapest Available' cabin.
On the same search on qantas.com.au, I see availability for 'Red e-Deal' fares, at more than $100 less.
Does ITA Matrix not show QF 'Red e-Deal' fares? Does it make a difference since I'm signed into my QF account?
