Hi everyone. I have read many posts but still couldn't decide which program to focus on. Thanks in advance for ur help.

I have Cathay's silver status now, which is a OW Ruby. It doesn't give me any actual benefits when I am not flying with Cathay. In addition, to keep the status and to attain higher one in Cathay is really painful...so I am considering switching to *A.

(1) What is your home airport?
My base is CAN (Guangzhou), and HKG is okay for me as well. However, I also spend a lot of time in the US. Most of the time I fly between JFK/ORD/LAX and HKG/CAN.

(2) What types of fares do you usually buy ?
Most of the time would be Economy Y, but sometimes when flying between Chinese cities, First Class A is also a choice.

(3) How many miles do you usually fly each year?
I could only answer this question in a two-year basis. I normally fly three round trips between US and China in two years. After adding up some short haul flights in US and China, it turns out to be around 45-60K in two years.

(4) What is most important to you in a FFP?
Priority Services, lounge access, and upgrades

(5) Preferred Airlines
I prefer OW Cathay, but the FFP is changing my mind.

The question I have is to choose between A3, OZ and UA.
Since A3 may or may not change its requirements to keep the status, I am not sure if it is still worth to get it. After attaining A3, I can choose UA since UA is a superior program in redeeming miles. The problem is, if A3 changes requirements, I have no other backup plans for *Gold.

I can get OZ's status easily, but OZ's miles are not that competitive to UA.

So could talkers plz give me some advice? A3+UA, A3+OZ, OZ+UA or OZ only?
Thanks a lotttttttttttt!!!
