I've had a bit of a look around just now for J/PE seats to LHR, LAX, YVR, HKG and BKK and don't see any of this extra availability! Has it been snapped up already or has Qantas just not released that much?
Edit: If I log in I can see some seats 11-12 months out (as a Gold member). But still not seeing much other than that.
I had a quick look around the dates I have currently booked for SYD-SFO (so Mar/Apr 2022). There was maybe one or two extra PEY seats released, but otherwise nothing
