Hi there,

I am strongly thinking about going for DONE4 but I am still new to OWE RTW and would appreciate your inputs. I am flexible with originating position, but based on what I read here and EF, CAI still remain cheapest place to start? I would like to explore Europe, South America, and Asia, along with few months break between trips so I'll go for DONE4 but open to add Africa if it doesn't cost too much.

CAI-xAMM-xDOH-MOW-PRG-xDOH-JFK-SCL-BOG-GRU-xJFK-TYO-HKG-SIN-DOH

Hope I did follow the rules properly with this route, but feel free to make suggestions how I can improve this routing, TIA.
