Route notes
Why this routing works
This itinerary is built as a multi-stop South America routing with a clear west-to-south progression: Pereira to Cartagena, Lima, and La Paz, then an overland break to Sucre before flights resume in Chile. Structuring the ticket this way separates the non-flight segment cleanly while preserving the onward sequence into Calama, Santiago, Easter Island, Montevideo, and Buenos Aires.
The Chile section is timed around a necessary Santiago return, with a short stop before Easter Island and a longer stay after coming back from the island. That sequencing keeps the Easter Island flights embedded within the larger ticket rather than treated as a separate side trip, which can simplify the overall flow of the itinerary.
The final portion moves efficiently from Chile across the southern cone to Montevideo, then finishes in Buenos Aires without backtracking. In economy class, this kind of open-jaw and overland combination is typically about making the route logic work first: using flights for the long hops and leaving room for a surface segment where the itinerary naturally shifts between countries.
With only 1 week shown for total duration, the routing reads as flight-focused and tightly sequenced, especially with multiple short stays early in the trip and a longer stop in Montevideo near the end. December departure timing places the whole itinerary in the Oct-Dec season window provided.
