Should I book a round-trip ticket or two one-ways?

Round-trip is almost always cheaper for South America flights, sometimes by $300-500. Only book one-ways if you're genuinely unsure about return dates or planning extended overland travel.

When do South America flight sales typically happen?

Major sales occur in January-February for travel later in the year, and September-October for travel the following year. Follow airline newsletters and use price tracking tools.

Are connecting flights through Europe worth considering?

Sometimes yes — KLM via Amsterdam or Iberia via Madrid can be $200-400 cheaper than direct US flights, but add 4-6 hours travel time. Good option if you don't mind the extra time.

What's the baggage situation for South America flights?

Most include one checked bag (50lbs) on international routes, but budget airlines like Sky Airline or JetSmart charge extra. Always verify baggage allowances when comparing prices.

How to Book Round-Trip Flights to South America

Book South America flights 2-3 months ahead for best prices, typically $600-1200 from North America. Use multi-city search tools, consider flying into major hubs like Lima or São Paulo, and be flexible with dates since shoulder seasons (April-May, September-November) offer significant savings.

Choose your entry point strategically. Fly into major hubs for better prices and connections: Lima (LIM) for Peru/western routes, São Paulo (GRU) or Rio (GIG) for Brazil/eastern routes, Buenos Aires (EZE) for Argentina/southern cone, or Bogotá (BOG) for northern South America. These cities have the most international flights and competitive pricing.
Search 2-3 months in advance. Start monitoring prices 3 months out, book 6-8 weeks before departure. Use Google Flights' price tracking feature and set alerts. Prices typically spike 2-3 weeks before travel and during peak season (December-March).
Use multi-city search if visiting multiple countries. Search for open-jaw tickets (fly into one city, out of another) rather than round-trip if you're covering ground. Example: Fly into Lima, overland to Buenos Aires, fly home from there. Often cheaper than backtracking.
Check both direct and connecting flights. Direct flights from major US cities cost $200-400 more but save 4-8 hours. Common connection points: Panama City (Copa), Houston/Miami (United/American), Madrid (Iberia). European connections via Madrid or Amsterdam sometimes offer better deals.
Be flexible with dates and consider shoulder seasons. April-May and September-November offer 30-40% savings versus peak season. Use flexible date searches (+/- 3 days). Avoid Christmas/New Year when prices double. Flying Tuesday-Thursday typically saves $100-200.
Book directly with airlines for South America. LATAM, Avianca, and Copa often have better deals on their own sites versus third-party booking sites. They also handle changes/cancellations more smoothly for long-haul international routes.
