Here is my ideal routing:
LAX-SYD (travel in Australia would be based on what fit our needs while there, either an airpass, some train or bus travel etc)
Australia to New Zealand (figure we'd do that near the end of our trip to get advanced purchase for a 1-2 day trip to meet with Maori)
Australia - Japan (same situation in Japan where we move around ourselves as needed)
Japan- Bangkok, Thailand
Thailand - China (need to check out visa requirements, mostly want to see the great wall and more of a tourist stop than anything)
China (or Thailand) - Calcutta, India (same travel plans as above)
India - Isreal (relatively short trip, huge fan base there surprisingly enough!)
Isreal - Europe (once we're in Europe we'll be touring in a Tour Bus).
Perhaps -
LAX-AKL-SYD-<Oz>-NRT-BKK-HKG-PEK-HKG-DEL-CCU-DEL-LHR-TLV-LHR-LAX
That won't actually work because it has too many segments in Asia and there's no Oneworld service from DEL-CCU. You can check the validity of a Oneworld routing
here, (plug the routing into the "Oneworld Explorer Validator" box). Though the list of routings (Oneworld flights) this tool uses isn't always fully up to date, it's useful for helping to validate a proposed routing and/or playing with it to see what works.
