Interestingly, AA does not recognize OW status for BE. Rather it reserves status benefits for AA only and then includes BA, IB, and AY.

Elite benefits may vary for flights marketed and / or operated by British Airways, Iberia or Finnair.
AAdvantageŽ elite status members and eligible CitiŽ / AAdvantageŽ or AAdvantageŽ AviatorŽ MastercardŽ cardmembers are exempt from certain restrictions.

We'll have to see how this shakes out as BE for international has not existed for an appreciable period of time.
