I hate to open another thread, but perhaps I should -- I've pondered joinging the CX program or BA, mainly because I hate not being able to use the SFO-LHR nonstops on BA.
I fly pretty much KUP domestically in the states, and a lot of I/D fares with a few others mixed in. Last year in AA I had a point/mile ratio of 1.4.
I've got about 36,000 points amassed this year but have an AONE3 coming up as well as some other flights, so I could still generate some points in other programs...but is it worth it? Both BA and CX seem less "friendly" in benefits, but as much as I've tried to dig and search, I'm still not sure.
