Am finally about to ticket my oneworld six continents itinerary. Please let me know if you think any of it breaks certain rules or if you have any suggestions on maximizing mileage. Although the stopovers are "musts", the order in which they occur is not. An o indicates a stopover whilst a x indicates a transit. Thanks for your help!!
