Route notes
Why this routing works
This 23-week business-class round-the-world itinerary starts in Los Angeles and uses two overland sections to reduce backtracking in the ticketed flight path: Los Angeles to Seoul, overland to Milan, then overland from Milan to New York City before returning to Los Angeles. That structure works well when some long-distance movement is handled outside the flight ticket while still preserving a clear westbound-to-eastbound sequence.
After the New York City overland endpoint, the routing resets through Los Angeles before continuing to South America. The final ticketed section is Los Angeles to Buenos Aires, then onward to Sao Paulo, and back to Los Angeles. With 26 nights in Buenos Aires and 2 nights in Sao Paulo, the South America portion is weighted toward a longer stay in one city with a short final stop before the return.
From a ticketing standpoint, this is a complex multi-continent build rather than a simple circle route, because Los Angeles appears multiple times and the itinerary mixes flown and overland sectors. Pricing is listed from USD 9,204 to USD 14,040 in business class, with August departure timing within the July to September season window. That makes timing and segment order central to keeping the route coherent across Asia, Europe, North America, and South America.
