My suggestion would be to start banking points as quickly as is humanly possible.What's the strategy here? Book rewards for beyond the changes and cancel/rebook if truely positive options become available next year??
If Qantas moves to dynamic pricing or some tiered reward structure, they are going to throw out a lot of low rate redemptions (quite possibly lower than current prices) to soften the blow. My guess is that there's going to be a once in a lifetime opportunity to fly on premium routes for bargain prices. Once the good news cycle is over, they will hike prices and the window will be shut.
