I'm planning to travel to Europe, (Germany,) end of June 2013 and am wondering whether I should hope for a sale of the upgradeable fares for mid 2013. At the moment I can get a return SYD - FRA with QF (Sale fare=non-upgradeable) for $2068. The same trip on an QF upgradeable ticket would cost me $3274. Should I hope for sale of these fares? I do not feel like paying $1300 more for a chance for an upgrade. Should I consider other oneworld airline and hope for an upgrade? Thanks for your thoughts.
