Does the AA RTW desk have any other contact methods, or just the phone number in Dallas?

With the booking tool as it is, I'm looking at other options to book. Current plan is to contact the RTW desk to set it up, then pay at the AA ticketing desk at NRT when I'm there in mid August (assuming I have it all planned out by then. Damn QF program/flight changes causing planning delays). But given my last experience with the AA RTW desk, I don't exactly relish the idea of making several long international phone calls.
