yes,i will be on my first round the world trip next jan-sep 2009 and my first leg is LHR-HKG and she wants to come to HKG with me flying BA and as she doesn't care about miles,i thought i could collect both my and her miles on LHR-HKG but honestly,that would have been too good to be true.
anyways,thanks for all your answers,guys.

no, dh01, it's not so difficult to understand! i was just trying to find a way to avoid both her having to open an aa account she will never need again and to pay that fee...
