Trying to change the date of my QF27 (SYD->SCL), which I booked as part of my DONEx, but facing a very sad picture in terms of availability.
According to expertflyer, the entire month of March 2025 is zeroed out on the flight for any business booking class but J and C. I know that the PoS might change things, but not optimistic that EG might have better availability than US.

Does anyone have experience with this route and the sales / booking class strategy from QF?
Is it likely that this will remain all zeroed out or is there hope for QF to release seats in the D booking class?
