I am in Australia on an AA-issued RTW, and would like to make route changes for later this month. I have had little help when I telephoned AA here (she can't even view the reservation in her computer), and QANTAS also can't see entire reservation and directs me back to AA. (Even at airport, QANTAS can't help with AA flights, they say). What I will do is call the AA RTW desk in the USA (on my dime from New Zealand), make the booking changes, and then hope I can handle the reticketing during a 2-hour layover in LAX.
Anyone have similar experience or suggestions?

Thanks.
