I am very pleased to have found all of the resources on flyertalk. It is fantastic!

I am planning a LONE4 ex CAI but, am discouraged by the ability to only stop over once in North America. My plan was to start in CAI, travel around and stop in the US.... make a trip to South American (hence the LONE4) and stop back in the US on the way to Europe to finish the trip. Apparently that is not allowed. Is there any way around that restriction?

MY planned itinerary is:

CAI-LHR-BOM

overland to SIN (can't get to SIN from BOM or MAA that I can find on One World)
SIN-HKG-PEK
PEK-HKG-YVR
YVR-DFW-CLT (stop here for a while)
CLT-DFW-SCL-PUQ
PUQ-SCL-IAD (stop here- This is the problem)
IAD-LHR-MXP
MXP-LHR-CAI

If I can't add the Patagonia trip, I guess I am stuck with a LONE3 without South America and that isn't what I had in mind.

Any suggestions to re-route any of the North American Segments (or buy an add on ticket) that will make this work?

Thanks;
Edward
