I would skip the FL at LAX and just head to the QF FC, assuming you have access. All of the FL's seems to have taken a step down in terms of quality, especially the F+B offerings.
2.69x EQD's on AA so not as good as the OSL/ARN/CPH WT+ fares. My last OSL-LHR-LAX was 3.39x, and I'm waiting on my EU compensation to be "heard" by CEDR as BA cancelled my LAX-LHR since they reassigned our aircraft (a 787 obviously,) and cancelled. Stick to the A380 flights as the upper deck WT+ is good, very quiet, and comfortable if you have a bulkhead or at least the aisle. Some like the window with the "arm rest" storage area, but it depends on what you like.
