Thanks, but I think that information is for BA miles redemptions for flights on BA and/or one partner airline.

BA oneworld awards are for flights on
* Two or more oneworld™ partner airlines, not including BA or
* Three or more oneworld™ partner airlines, if the itinerary includes BA

The information on the BA website https://www.britishairways.com/trave...g/public/en_gb only specifies the miles needed for the economy cabin on these awards, not business and first class. I don't know if it's safe to assume that the miles required are the same as for BA only / one partner awards i.e. 2x for business and 3x for first class.
