I am considering a June trip to TPE and would fly BR in a heartbeat just to check it off my *A partners list and a quick glance at the earning grid they currently have with UA, I would likely earn at least 75% percent mileage for my Economy fare, whereas, we know AC would only earn 50%. Right there, I will give BR a try.
My only hesitance right now is that knowing that AE and UA earning charts don't always match up, I could be screwed by booking this early.
Not sure what to do as yet.
