For a leisure traveller such as myself, mainly in Y, the changes are a terrible. The longhaul to Europe in J has almost doubled the miles needed!!! The 50% award wont even bring it back down to present levels.....
The before/after mileage award redemptions on TG are as follows:
AKL-BKK return Y. 75,000, from Oct 83,000 (11% increase)
AKL-BKK return J. 130,000, from Oct 170,000 (31% increase)
AKL-LHR return Y. 90,000, from Oct 170,000 (89% increase)
AKL-LHR return J. 170,000, from Oct 350,000 (206% increase)
