It's gone live. Redeeming a simple SIN-HKG one-way in Y looks like the following:



No, I don't think I'll be rushing to do this anytime soon... Ironically, 65,000 miles is enough to redeem 2x F Saver on the same route.

PS. Bookings that have been part-paid with KF miles will apparently only earn miles with KF (i.e. can't credit to other Star partners), and will only earn the pro-rata amount of miles corresponding to the amount of cash paid. So, if I pay for this SIN-HKG with ~65,000 KrisFlyer miles, I get... zero miles! And if I pay 10% of the amount in cash, I get 10% of the usual miles I would earn...
