AA/LA are both in Sabre - it should be updated for both...
BA/AB/IB/AY/CX/JJ/QF/QR/RJ are all in Amadeus (although IB is also in a older system as well, hence some seating trouble) and will see each others update easily.
Sabre/Amadeus status updates can sometimes take some time - but Sabre/Sabre?? If it's still happening for the OP, then LA can't repush the status to AA - but AA can certainly call their oneworld helpdesk as and when they need to verify a status.
