I was looking at YVR/SFO-AKL a few days ago on FJ; can confirm they've jacked up the one way fares to 400k through MileagePlan. Check out BA - I am seeing late March 2026 availability SFO-NAN for 77k Avios in J.
FJ is absolutely not worth 400k each way, even in the A350. This is what I'd expect at SkyPeso prices.
