Thanks for posting! I have found that AA ticketing may take up to 48 hrs, but you can always call the RTW desk and check on progress. I'm not sure if the agent has any way to "push" things along, but YMMV.
The cc charge will show as pending for a while, even after ticketing is complete. Who knows why.

Good luck if you voluntarily choose the OW tool -- I have found that any "crazy" itinerary will almost certainly trigger an error, even if it's a legit routing... or it may offer you only one carrier, despite having availability on multiple carriers.
