Can anyone give advice as to the “success” of upgrading from Premium Economy to Business on CX flights Perth to Hong Kong & Hong Kong to Toronto, using Asia Miles?
How difficult is it to upgrade from Premium Economy to Business Class on Cathay Pacific flights using Asia Miles?
I do quite a few redemption flights with Cathay. I assume the upgrades work similarly. In my experience you have to plan way out (like 360 days, as the availability it released) or wait til just a few days out when they release unsold seats. The second option is fine if you have lots of flexibility, but you don’t get any certainty that a seat on a specific flight will become available.
