I -feel- like there's some trepidation in the threads I've been reading through, or maybe it's simply a desire to not deal with re-issues down the line. But I always found them kind of "fun" believe it or not.

The Sabre PNR still might not have all the post-AA flights, and it could potentially be an issue with AA not being able to see the original PNR. But none of that is new, and in my experience the AA RTW desk has been very helpful in reworking partly-flown RTWs. So, I don't see any reason not to try it. In the absolute worst case, the AA RTW desk is unable/unwilling to help, so you fall back on Plan B and have the original ticketing carrier make the changes.

For sure.
