I've already purchased one travel package (we'll be spending the 7 nights at the Parc 55 in SFO ^), and I dumped the miles into my AA account.

It turns out I could use some miles in more than one account. So the next time I buy a package, do all the miles have to go into a single account, or can I put, say, half in one account and the balance in another?

Would this actually be "forbidden" or could I work it out with the Platinum desk, or what? Chris?
