AA forum is better place to ask.
Yes, perhaps technically it is difficult to transfer miles between One World members.
However, there is no need to transfer miles. Merely give the AAdvantage number at booking and ask that the miles be credited initially to your AAdvantage account.
Note that this only works within the One World alliance or with AA partner airlines.
