I'm still in BKK, but I will say my outbound in CX's PE was very good. I'll post a review when I get back - but mileage wise, I did much better with AA's program than I would have done with BR; even the lowest PE fare on CX gets 110% AA miles.
I will miss being a big fish in a pretty small pond, but I forgot just how much I enjoy transiting HKG over TPE.
