If that's an AA code-share flight, and your ticket shows the AA flight number, you would probably be let in. The version of the rules I just checked talks about being admitted on the day of "your oneWorld flight," but doesn't say whether that means marketed by, operated by, either, or both. At least you could make a good case.
That doesn't move the AC to the right terminal, though.</font>
Actually the odds are low. The rules are quite explicit in
"All oneworld benefits are available only to passengers on scheduled flights that are both operated and marketed by a oneworld member airline. "
