No outright award seats available on dates we can do unfortunately so will go with our upgrade changes which hopefully should be pretty reasonable.
Thw lounge is still just a lounge to spend an hour or so before the flight - the flight to Europe is the main thing - a short time in lounge plus quite feasible 24 hours in economy (or premium economy if purchased) vs using the Singapore lounge at Sydney and a guaranteed business class journey - to me it is a no brainer decision
