25% extra is wishful thinking. Looking at how the US carriers do it, we're probably looking at multiple hundred thousand points for last minute Upper Class flights...
I voted 10% extra in points. If taxes for UC stay the same as 1k per person for a return trip, I could not bear myself to pay more than 10% extra in points... if they are going to increase the price in points of reward seats, they need to start refitting the 787's.
