I'm thinking about building my RTW in Sabre (I use a host agency), queuing it over to AA to price out, and then issuing the ticket myself. I want to do this for all the standard reasons people like to book complex itineraries themselves (mainly, to cut out constantly being on hold with a bunch of agents on the phone).

Are there any huge disadvantages to doing this? My worry is that I'll be somewhere in the world with no Sabre access and I'll need to make a change to my itinerary (most likely just a date change, not a reroute). I know DL now charges a fee for making any change to an itinerary booked by travel agents but I haven't found evidence that AA does this as well.

By the way, for those of you trying this at home: You don't need to queue the PNR to the regular international rate desk queue. RTW has their own pricing queue--QP/TUL91/11.
