Cathay Flights booked through AA (upgrade questions)
Hoping I can get some clarity on using AM miles to upgrade on a Cathay Pacific flight but booked through AA.COM.
Looking at booking flights from NYC to Hong Kong & Singapore back to NYC during the Christmas break. The flights I am looking at are:
12/17 JFK-HKG CX845
01/01 SIN-HKG CX714
01/01 HKG-JFK CX830
It seems that if I booked through AA, the flights are significantly cheaper than booking it directly with Cathay. My question is, if I have a lot of AM miles, can I apply the miles to upgrade this flight if booked through AA. Also, what are my chances of getting upgraded during this busy holiday time.
