I just found a potential change from PMUA regarding non-*A partner award redemption, although it's probably interesting to only a fraction of folks.
At PMUA MP, each non-*A partner had its own award chart, which was often more expensive than the *A chart for the same region pairs. On the preview site, however, non-*A partner pages just refer to the generic *A chart. It is very possible that they haven't created all the new charts yet, but if this is true, I might be interested in redeeming miles for some of those partners (say QR).
