I couldn't find this info clearly laid out on aa.com, so I thought you would be the ones to know this answer.

Can you use AAdvantage miles to upgrade on other OneWorld Partners? If yes, what are the rules/mileage charts?

I'm trying to get from US - India on somewhat short notice and an upgrade is of paramount importance to me. UA won't let me upgrade on *A partners (except LH, which has rules that virtually eliminate it as a possibility) using MP miles. If I could get miles from an AA member, could I upgrade on BA or Cathay Pacific?

Thanks
