Hi there,
I’m based in Paris and although usually it’s easier from here to find availability it is very erratic.
I’m not on my phone so I can’t see what your home airport is but I had the same problem finding availability so I booked EY in F to Australia... I did a lot of research and the F apartment is incredible. That’s what I would do :-)
My return is in J on QR (consensus is that it’s not worth using extra miles on QR for F).
Anyway good luck!
