If you want your AA flights to earn Asiamiles credit, yes, you give AA your Asiamiles account instead of AA # during booking and checkin.
It does CX a while to credit your account though. Do keep your boarding passes and ticket until miles credited. I had to send fax to HK when CX failed to credit my parents's Asiamiles accounts for their domestic AA flights.
