Should I book everything on one ticket or separate flights?

One multi-city ticket protects you if flights are delayed—airlines will rebook you automatically. Separate tickets are cheaper sometimes but you're on your own if connections are missed. Choose based on your risk tolerance and price difference.

Which airlines have the best South America networks?

LATAM has the most comprehensive network, especially for Chile, Peru, and Brazil. Avianca dominates Colombia and connects well to North America. American, United, and Delta have good partnerships for US travelers.

How far ahead should I book?

2-3 months for international segments, 4-6 weeks for regional flights. Don't book too early (6+ months) as route schedules change frequently in South America.

Can I add cities to an existing ticket?

Usually no without paying change fees plus price differences. Some airlines allow free changes within 24 hours of booking. It's almost always cheaper to cancel and rebook than to modify complex multi-city tickets.

How to Book Multi-City Flights for South America

Book multi-city flights for South America using airline alliance tools or third-party platforms like Google Flights or Kayak. Build your route around major hubs like Lima, Santiago, or São Paulo, and book 2-3 months ahead for best prices. Expect to pay $800-1,500 from North America depending on cities and season.

Map your route around major hubs. Start with Lima (LIM), Santiago (SCL), São Paulo (GRU), or Buenos Aires (EZE) as anchor points. These cities have the most international and regional connections. Avoid starting with smaller cities like Cusco or Mendoza unless you're willing to pay premium prices.
Use multi-city search tools first. Start with Google Flights multi-city tool or airline alliance websites (Star Alliance, OneWorld, SkyTeam). Enter all your cities in logical order. Don't search each leg separately—you'll miss connecting flight deals and waste money.
Check South American airline hubs. Search LATAM (strongest network), Avianca, and GOL directly. LATAM dominates Chile, Peru, and Brazil routes. Avianca covers Colombia and connects well to Central America. These airlines often have deals not visible on third-party sites.
Compare round-trip vs open-jaw pricing. Sometimes flying into one city and out of another (open-jaw) costs less than a true multi-city ticket. Compare: round-trip to your first city + separate one-way flights vs. multi-city routing vs. open-jaw pricing.
Book regional flights separately if needed. If multi-city pricing is too high, book your main international flights first, then add regional segments. Budget carriers like JetSmart, Sky Airline, and Viva Air cover routes between countries for $50-150 per flight.
Allow buffer time for connections. Build in at least 3 hours for international connections and overnight layovers for tight schedules. South American airports can have delays, and missing a connection ruins multi-city ticket savings.
