Sorry, I just can't agree with those who think it's a good deal to part with 100,000 FF to buy retention of their QF Platinum status, or 80,000 to retain Gold. This is NOT a good deal!
To start with, if you use your points just for Business Class travel, then 100,000 pts is typically worth around $3,000 and that's a lot of money to justify status retention. Even for Economy travel, the value is around $1,000.
To add to this, I see it as poor behaviour and a lack of respect on the part of QF, because they have already declared their hand - and told us the actual value of status credits. At every 500 SC level, QF offers an extra 50 SC or 8,000 pts ... therefore QF has clearly declared their hand in pricing the value of 50 SC as 8,000 pts (or visa versa). If you were offered 50 SC or 80,000 pts, then this is a whole different story!
So, for those of you at Gold, sitting at 500, or 550 and being asked for 80,000 QF pts as a 'gracious' offer to renew, surely if you're only 50 pts short you should be being asked for only 8,000 points, not 80,000 !!! ... because that is what QF themselves are saying 50 SC translates to.
