South America is a huge continent, which means the most popular months can vary depending on each region and what you plan to see and do. September to November are often considered to be good months to visit. Several destinations, like Buenos Aires and Rio de Janeiro, experience mild, spring-like conditions. Summertime is high season in Patagonia, when hiking trails are easily accessible, and at the beaches of Colombia. Wherever you go, be sure to do some research beforehand. For example, July and August is usually peak time for Peru's Inca Trail, but it closes for maintenance in February. June to September is the ski season in Chile.

Many international carriers offer flights to South America from continental USA. They include American Airlines, Copa Airlines, LATAM Airlines and plenty more. The availability and prices of flights can vary according to each specific destination and the time of year you choose to fly. To see if your favorite airline flies a certain route, simply enter your departure and arrival airports into Expedia.
