If using Amex MR transferred to NH it's a high value redemption. But between HKG & the Philippines there are no nonstop Star Alliance flights. There are CX flights that one can use BA/IB Avios for redemption or a cheap paid LCC ticket. For getting to HK it's good to look at BR out of JFK,IAH, ORD, SFO or LAX and if need be SEA. Service in J is really nice, award availability tends to be good and the connection is easy. Do segment searches (for example SFO-HKG using the UA search tool for availability to built an itinerary and then feed the flights to the NH rep. Be sure to open your NH account now and get the paperwork done for your wife to qualify for a redemption.
