Route notes
Why this routing works
This routing is built around a necessary backtrack through Santiago: Dallas to Santiago, onward to Stanley, then back to Santiago before continuing north to Santo Domingo and Le Lamentin, with the trip closing in Dallas. That sequencing keeps the South Atlantic segment grouped together first, then shifts to the Caribbean for the final portion of the trip.
At four weeks in economy, this is a moderate-length multi-stop itinerary with a clear geographic progression across South America, the South Atlantic, and the Caribbean. Repeating Santiago as both an outbound and return connection point is the key structural feature of the ticket, and it helps link a less-direct stop into the wider route without breaking the overall flow.
Because this is an MSI rather than a simple round-trip, the ticket is doing several jobs at once: handling an open sequence of international stops, preserving the stop order, and wrapping the itinerary back to Dallas at the end. November timing places the whole trip in the October-December travel window, which is useful when planning connection spacing and the overall four-week pacing.
