Just on the minor point of "these fares are all that they do," a few years ago, AA merged their Meeting Services and RTW teams, so RTW agents also do group bookings. And they handle overflow regular calls. That minor quibble aside, yes, the AA RTW desk is an excellent choice for booking RTWs. They won't book another airline's code on an AA-operated flight, and they are not the cheapest for carrier overcharges, but those two fairly minor issues aside, there's no reason not to use them.
