Quick trivia question...the first one to know (or even have been to) all these airport codes gets a free drink...
The following routing is possible with this RTW ticket - all flights in business class, total cost (excluding taxes and fees) about 3,300 Euro:
CAI-xNBO-SEZ-xNBO-xJNB-CPT-EZE-xPTY-CCS-xPTY-UIO-xPTY-SJO-xPTY-xGUA-xIAH-NAS-xIAH-HNL-xMAJ-xKWA-xKSA-xPNI-xTKK-xGUM-ROR-xMNL-xKUL-MLE-xDXB-CAI
If you want to see how that looks on the map...

I'd probably never really do this one, it's just to show that this RTW seems to offer some interesting routings not possible with the other carriers...
