Thanks for your input Bolthead. I have a review date of 14 Dec 12 on my Gold and my partner has a review date of 21 June 12 on her Silver. The 15 Apr 12 date is when our first lot of SC start to expire if we do not reach the next level of membership, which is Platinum for me with 39 SC to go and Gold for her with 261 SC to go.
I did consider the strategy of getting her to Gold as we will have flights to Brisbane in March and OOL and MEL in April but thought it might be possibly better to work on gaining the 800 points for me to maintain the Platinum membership as we fly together. I thought giving up the 261 SC to her might affect me getting the Platinum 800 re-qualify and the Platinum would be more beneficial to us.
I suppose getting into the technicalities of it. The return Business flight on 26FEB will move me into Platinum, however the question is will the 160SC I get for this flight count towards the Platinum re-qualify or will 151 of them be in limbo and I will have to earn another 800 for Platinum re-qualify. Hope I explained that part clearly enough.
