These are really good suggestions.
I did love the QF5/QF6 flights though, they were so convenient and saved a lot of time. Almost effortless to get to my desired location. Also, I do need to pay J to maintain status...
I was just surprised that the Qantas prices are SO significantly more expensive compared to when I booked the same flights in March this year for flights only a few months later, when demand was already high and the invasion had already started (remember I am specifically comparing Qantas' prices for specific routes, and not comparing the prices of other airlines).
Maybe the fares will decrease a bit when a sale comes on, or maybe I just need to consider the other helpful options of booking a less convenient route.
