Twenty countries, split three ways. Nine sit in South America: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru and Uruguay. That block is what most buyers come here for, and it carries the whole Andean backpacker loop on one plan.
Six more sit in Central America: Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama. This surprises people. A plan sold under a South America name will also carry you down the Central American land route without a second purchase, which is the kind of detail rival hubs leave you to guess at.
The last five are Caribbean territories: Guadeloupe, Martinique, Puerto Rico, Saint Barthelemy and Saint Martin. Puerto Rico is the odd one out, a United States territory sitting on a Latin America plan. It works because the plan is built on Claro's regional footprint, and Claro operates there. Orange carries the four French islands.
