Does anyone know why Qantas does not accept flight upgrades when u choose to upgrade a booking. I am GFF and in the past have always been able to upgrade a flight booking. Now when I try it says no upgrades are available at this time when I know via Expert flyer that there are upgrades available. Is this a qantas problem or the rules have changed re upgrades being available until close to departure. Apologies if this enquiry has been already answered.
