Should I book multi-city or separate flights?

Multi-city tickets offer protection if flights are delayed and often include better routing, but separate tickets with budget carriers can save 20-30%. Choose multi-city if you're traveling during peak season or have tight connections.

Which airlines have the best South America multi-city options?

LATAM has the most extensive South American network, followed by Avianca. For international routing, American Airlines and United have strong partnerships with local carriers. Copa offers good connections through Panama City hub.

Can I change dates on multi-city tickets?

Most multi-city tickets allow date changes for $150-300 per change, but route changes are usually not permitted. Book flexible fares if your plans might shift - they cost 15-20% more upfront but save money on changes.

How far in advance should I book?

6-8 weeks ahead offers the best price-to-flexibility ratio. Earlier booking (12+ weeks) doesn't always save money on South American routes, and last-minute deals are rare during peak season (December-February).

How to Book Multi-City Flights for South America Travel

Book multi-city flights to South America by using airline alliance websites or Google Flights' multi-city tool. Start with major hubs like Lima, São Paulo, or Bogotá, then add 2-4 additional cities. Book 6-8 weeks ahead and expect to pay 15-25% more than round-trip tickets but save on separate bookings.

Choose your South America route strategy. Pick either a loop (starting and ending in the same country) or linear route (entering one country, exiting another). Popular loops: Lima-Cusco-La Paz-Santiago-Buenos Aires-Lima. Linear routes work well with overland travel between some cities.
Start with major gateway cities. Begin your search with South America's main international hubs: Lima (LIM), São Paulo (GRU), Buenos Aires (EZE), Bogotá (BOG), or Santiago (SCL). These have the most international connections and competitive pricing.
Use Google Flights multi-city search. Enter up to 5 cities in Google Flights multi-city tool. Input your departure city, then add South American stops in logical geographic order. Search flexible dates if possible - weekday departures save 20-30%.
Check airline alliance websites directly. Search Star Alliance, OneWorld, and SkyTeam multi-city tools. LATAM, Avianca, and Copa often have better South America routing than global search engines show. These airlines know regional connections best.
Compare with separate tickets. Price out individual flights between your cities using local carriers like LATAM, Avianca, JetSMART, or Flybondi. Sometimes separate bookings cost less, but you lose protection if flights are delayed.
Book with 24+ hour layovers. Build in long layovers (24+ hours) in major cities to count as stopovers, not connections. This lets you explore gateway cities like Lima or São Paulo without extra flights.
Confirm visa requirements for each stop. Verify visa requirements for every country you'll enter, including brief layovers. Some countries require visas even for transit passengers. US citizens need visas for Bolivia and sometimes Brazil.
