Reply: Qatar, but flying Cathay more since they join OW. Sometimes AA US domestic.

I am deciding between Qatar and Cathay. One biggest factor of the move is that I cannot upgrade using mileage in OneWorld airlines with Qatar's mileage. Plus Qatar is getting more and more expensive in their business class. Is the move worth it? How hard is it to earn CX Diamond membership?

Thanks!
