Like johnp012001 says, the ticket no. is included in the e-mail confirmation.
AS has to have the AA ticket number, otherwise, it wouldn't let you on the plane. The e-ticket virtual "coupon" has to be used by AS for them to get paid for the flight, and it must be accessible in some field by the AS agent.
