Allow me to bump this thread as it seems to be the most relevant.
I just recently flew BA and I didn't request for mileage crediting: I have an Asia Miles account and my flights will not earn any miles with CX. I'm also flying MA this week. If I presume correctly, standard procedure would dictate that I have six months to request retroactive crediting of miles, hence why I'm program-hunting for oneworld.
My shortlist so far seems to be BA/IB or AA. Which program is the best for me?
