Any idea why Qantas would have a block out period for Classic Reward flights from Sydney to all New Zealand cities from 10 December 2021 - 9 January 2022? There is plenty of availability both before and after these dates, but all NZ cities have this blackout with no classic reward availability for that month period. I haven't seen it before, and we were able to book classic reward flights for the same period last year (well actually January 2021...which of course covid meant we were unable to use).
