Should I book all flights at once or separately?

Book multi-city as one ticket when possible for better protection if flights are delayed or cancelled. If price difference is more than $300, consider booking separately but buy travel insurance.

Which airlines have the best South American networks?

LATAM Airlines Group has the most extensive coverage, especially for Chile, Peru, Brazil, and Argentina. Avianca covers Colombia, Ecuador, and connects well to Central America. GOL and Azul are good for Brazil domestic routes.

Can I change my multi-city itinerary after booking?

Changes typically cost $200-500 per ticket plus fare difference. Some flexible fares allow free changes. Book refundable tickets if your plans might change, especially during rainy season when weather delays are common.

Do I need to collect luggage between flights?

On single tickets with partner airlines, luggage usually transfers automatically. On separate tickets or different airline groups, you must collect and recheck luggage. Always confirm at check-in and allow extra time for customs/immigration.

How to Book Multi-City Flights Through South America

Book multi-city flights through South America using airline alliance tools or travel booking platforms that support complex itineraries. LATAM and Avianca offer the best route networks, while Google Flights multi-city tool helps compare options. Expect to pay 15-30% more than round-trip flights but save significantly versus booking separate tickets.

Map your route and timing. List your desired cities in logical order to minimize backtracking. Popular routes: Lima-Cusco-La Paz-Buenos Aires-Rio de Janeiro, or Santiago-Buenos Aires-Montevideo-São Paulo-Bogotá. Allow 3-7 days minimum between flights for each destination.
Check visa requirements first. Some countries require advance visas that take weeks to process. Brazil requires visas for US citizens (14-21 days processing). Argentina, Chile, Colombia, and Peru allow 90-day tourist entries for most nationalities.
Use Google Flights multi-city tool. Go to Google Flights, select 'Multi-city' instead of round-trip. Enter each leg separately with flexible dates (+/- 3 days) to see price variations. This shows all airline combinations and identifies the cheapest routing.
Compare with airline alliance booking. Check Star Alliance (via United or Avianca websites) and oneworld (via American Airlines) multi-city booking tools. LATAM Airlines Group covers the most South American destinations and often offers better multi-city pricing than booking separate tickets.
Consider open-jaw tickets. Fly into one city (like Lima) and out of another (like Buenos Aires) with overland travel between some destinations. Often cheaper than full multi-city flights and gives you flexibility for buses or domestic flights.
Book 6-8 weeks in advance. South American flight prices peak during local summer (December-February) and Easter week. Book domestic connections after securing international routing, as last-minute domestic flights are often available and cheaper.
Build in buffer time. Allow 4-6 hours minimum for international connections, 2-3 hours for domestic. Weather delays are common in mountain regions (La Paz, Cusco) and during rainy season (November-March in northern countries, June-August in southern regions).
