The email does mention 15%, but when it comes to the calculation side, it adds on another 3% onto your VFF account.
ERewards is no longer my best mate when it comes to earning points.
Will now look into booking MEL - WLG and then WLG - MEL - ADL with FB travel in J and watch the points come in.
Yes, eRewards is "points for not spending $, but spending time/wasting time", might as well spend a bit of $ and earn VFF points and also more importantly, VFF SC!
WLG - MEL - ADL is quite cheap, Nzd$7xx in discJ! All on the one PNR. Even cheaper at Aud$1k if MEL - WLG - MEL is booked as a return in discJ.
So, earn FB points transferable to VFF for the booking with FB travel, plus 15% bonus for the future transfer, and then earn VFF and VFF SC for the flights.
Sorry for the offtangent, but FB has a lot of ways of earning VFF points than eRewards.
