tl;dr
With all the changes happening at CX I am considering my options in OW.

A little bit of background:
I am based in PVG and in the past travelled mainly to the US and Latin America. Mostly in Y.
I became EXP (OWE) in my second year and stayed EXP for about 3 years.
Generally I liked being EXP, especially for the crazy mileage earning and low redemption rates.

Then my travel profile changed and now I was travelling to the Middle East and Southern Africa more. Being in PVG CX was a good choice for me to reach these, but as many CX Y fares do not give miles on AA or just 50% I was looking for a change.
I heard good things about CXs program and the unofficial benefits. Got matched to Silver and hit Gold in the first year. Now I am Gold in my second year and on track to reach DM later this summer.
Up until about 6 months ago I was very happy with CX recognition and the occasional op-up happened as well, the last 6 month have been worse though. Reading in the CX forum this seems to be due to the "improvements" CX is implementing and planning for the future.

Now to my question:
I am planning to stay with CX at least until I reach DM. Maybe things will get better again once I hit that status and I will get hooked again and not look elsewhere anymore.

But right now I am considering to switch to AB later.

I am originally from Berlin and visit relatives about twice a year, I flew AB from time to time and think they are okay, so I think any requirements to fly them is easy.
The big advantage I see with their program is the possibility to credit EY miles to their program as well and reaching OWE faster than I would requalify on CX.

Any input on the situation or any would another carrier make more sense ?

Thanks for any input
