Route notes
Why this routing works
This three-week itinerary is built as a single multi-stop loop from Nashville to Cuzco, then onward to Istanbul, New Delhi and Abu Dhabi before returning to Nashville. The sequencing keeps the trip moving in one direction across four regions instead of doubling back between continents.
In ticketing terms, this is a clean open-loop structure with four intermediate stops and a return to the origin city. That layout is useful for travelers who want distinct long-haul sectors spaced by stopovers, rather than a simple out-and-back fare with repeated routing.
Timing matters on a route like this. Over three weeks, each segment functions as both a transit leg and a reset point before the next intercontinental flight, with the final Abu Dhabi-to-Nashville leg closing the loop in one push. In business class, that pacing is especially well suited to a compact trip that still covers widely separated stops.
