My friend has a complex itinerary coming up, so I wanted to tap the collective knowledge of the forum here regarding a LONE3 leaving from either the USA or Brazil.

First, how much does each one of these cost? I tried pricing the on the OW website but it errors out. I'm curious if it's cheaper than a bunch of separate tickets.

Here is the high level routing:

RDU-GRU(stop)-SIN(stop)-ATL(stop)-RDU

After doing some research, I came up with some routing ideas as follows:

RDU-MIA/JFK-GRU-LHR/DOH-SIN-HKG/TYO-LAX/DFW/JFK-ATL-RDU

I know that we can add more segments. Do you have any tips in that regard?

Any other thoughts?
