Are there any options to use FC mile to ugrade on partner airlines at all? I'm looking for flights to Tokyo in November What is the best routing? Hoping for some v-flyer wisdom. Thanks.
Miles can only be used for 100% reward seats on partner airlines, not upgrades.
So your options are to use miles for 100% reward seats on ANA (probably tricky) or to use miles to upgrade on VS to PVG or HKG and find a connection from there.
