When you are ready to reticket, send Emeco the information re flights you have flown, what is left, and what you are adding. They will send the info to Ireland for AA to reprice. AA then prepares a ticketing mask; it takes about 1 minute for an airport agent to issue the ticket. Do this after 4 segments are flown so that the new ticket can be machine printed.

I had a ticket reissued at the Charlotte Airport this way last year. The agent needed no knowledge of RTW pricing; it was all prepared for her. Worked like a charm.
