The ticket is owned, issued and serviced by AA - the travel agent will need to call AA sAAleslink to get a soon-to-be-very-annoyed agent who will be tasked with transferring the call to pricing, who will then spend an endless amount of time figuring out the new fare, who will then refuse to reissue the ticket, but send the TA into the reservations queue for the customer's status rank, if any, who will then reissue the ticket.

This is how it works today when the ticket is partially flown and the GDS can't handle the reprice and reissue....but going forward it will be for every AA ticket issued in this system regardless of coupon status.
