Hmmm. The more I think about this, the more confused I could get. If most of the carriers require an inter-continental hop to count the arrival, than the previous poster would seem to be correct - one RTW will only get one carriers full awards.
There seem to be two possibilities: to zig-zag in between adjacent continents en route E-W or W-E, or to add minor hop returns off the RTW ticket. The former is in the itinary, the latter depends on finding inter-continental desinations that are both close together and served by a OneWorld carrier (sorry for restating the blindingly obvious). So - what are the most interesting city pairs in this category? I would think that there should be something in the Caribbean that would give you US and S.America; following the islands I noticed Guam counts as Australasia, and so on.
Any suggestions?
