Another update (and success story for once). I'm planning on flying back home in February (home for me is Canada and DTW is the nearest airport from where that is). After checking on the loads I found the most ideal flight itinerary that had I availability : QF415 (SYD to MEL) > QF 21 (MEL to DFW) > AA 2508 (DFW >DTW). I called up the QFF Platinum desk and spoke to Karen who was lovely. Unfortunately, QF21 wasn't available for release
despite it being I5, she tried a couple more options and found one that would at least get me to the Americas in business: QF550 (SYD > BNE) > QF 15 (BNE > LAX) which I accepted. I'll now need to work out getting to DTW from LAX, but that shouldn't be too difficult.
And yes, I know it's QF 15 on an A330, it's no luxurious experience like on the A380 or 787, but you know what, it's a J seat and I'll take it!
