Before UA's massive first class partner mileage hike February 1 of last year, for me it wasn't even close....I only focused on UA in earning miles and flying. This year I finally began to realize the value of AA miles, in particular in first class to Asia, and I have begun to shift to AA. However, I am still burning through a lot of my UA miles. Next year, I'll likely shift all of my flying to AA/One World, IF (and it's a big IF) American does not insanely hike its partner redemption chart.

So, the ball is in AA's court. I don't really care if they switch to earning miles based on revenue (I mainly buy discounted Biz tickets to Asia), but I'll never fly AA if they insanely hike the mileage Biz/First redemption requirements...particularly to Asia.
