How to Find Cheap Flights to Argentina

The Short Answer

Fly from Miami on a Monday, book about 7 weeks ahead, and travel in January for the cheapest fares. LATAM, Aerolineas Argentinas, and American Airlines are your main carriers. Round-trip flights to Buenos Aires start around $585, but expect to pay more from most US cities without strategic booking.

Why Argentina Flights Cost More

Argentina is far. Buenos Aires is roughly 5,300 miles from Miami and 5,500 from New York. These are 10-11 hour flights requiring widebody aircraft and lots of fuel. There's less competition on this route compared to Europe or Asia, which keeps prices higher. Knowing this helps set realistic expectations -- a "cheap" Argentina flight is different from a cheap Europe flight.

Best Airlines for the Route

Top Carriers

• LATAM Airlines -- The most popular airline for the route. Direct flights from Miami with connections from other US cities via Latin American hubs like Lima and Santiago.
• Aerolineas Argentinas -- Argentina's national carrier with direct flights from Miami and New York. Competitive pricing and the most authentic Argentine experience (including dulce de leche on board).
• American Airlines -- Nonstop from Miami and Dallas to Buenos Aires. Good for AAdvantage members.
• Delta -- Nonstop from Atlanta to Buenos Aires (EZE). Seasonal service.
• United -- Nonstop from Houston and Newark.

Budget Options

• Arajet -- The Dominican Republic-based budget carrier sometimes offers competitive fares. Miami round-trips from $621.
• Avianca -- Colombian carrier connecting through Bogota with occasionally great fares.
• Spirit Airlines -- Budget fares on some routing through connecting cities.
• Frontier Airlines -- Occasional appearances on the Houston route.

Argentine Budget Carriers

• JetSMART -- Ultra-low-cost carrier with fares from $17 for regional and domestic flights. Great for getting around Argentina once you arrive.
• Flybondi -- Argentine budget airline with fares from $25. Domestic and regional routes.

Buenos Aires Airports

Ezeiza (EZE) -- Ministro Pistarini International

All international flights arrive at Ezeiza, located about 22 miles south of Buenos Aires' city center. The drive takes 30-60 minutes depending on traffic. Taxis and rideshares are available, as is the Tienda Leon shuttle bus service to downtown.

Aeroparque (AEP) -- Jorge Newbery

The domestic and regional airport, located right in the city. Some flights to nearby countries (Uruguay, Brazil, Chile) depart from here. If you have a domestic connection, you may need to transfer between airports -- allow at least 4 hours for this.

Best US Departure Cities

• Miami (MIA) -- The single most reliable cheapest origin. Most competition with LATAM, American, Aerolineas Argentinas, and budget carriers all serving the route. Round-trips from $585.
• Houston (IAH) -- United nonstop service with competitive fares. Popular connecting options through Spirit, LATAM, and Avianca.
• Atlanta (ATL) -- Delta nonstop with good sale pricing.
• Dallas (DFW) -- American Airlines nonstop with frequent award seat availability.
• New York (JFK) -- Aerolineas Argentinas and American nonstop. Higher fares but convenient for East Coast travelers.

When to Book and When to Fly

Cheapest Month

January offers the lowest fares, with prices averaging around $941 round-trip. This is counterintuitive because January is summer in Argentina -- but it coincides with post-holiday pricing in the US and lower demand from American travelers.

Booking Sweet Spot

Book about 48 days (roughly 7 weeks) ahead for the best fares to Buenos Aires. At this point, airlines have a good sense of demand and may discount unsold seats. During this window, fares average around $1,105 -- but deals below $700 pop up regularly for flexible travelers.

Best Day to Fly

Monday departures are cheapest, with fares as low as $1,151. Avoid Saturday departures when average prices jump to $1,335. That's a $184 difference just for choosing a different day of the week.

Savings From Connections

Choosing a flight with one or two stops can save up to 12% compared to nonstop routing. If your time is flexible, connections through Bogota, Lima, or Santiago often produce the best fares.

Money-Saving Strategies

Position Through Miami

Miami consistently has the cheapest Argentina fares. If you're based elsewhere, a cheap domestic flight to Miami plus a separate Argentina ticket can beat booking from your home city. A $100 domestic ticket plus a $585 Miami-Buenos Aires fare totals $685 -- often less than a direct booking from most other US cities.

Use South American Hubs

LATAM connects through Lima and Santiago, Avianca through Bogota. These connections add travel time but can save $200-400 compared to nonstop fares. The Lima connection is particularly efficient -- it's on the way.

Book Open-Jaw Carefully

If you're exploring Argentina and neighboring countries, an open-jaw (fly into Buenos Aires, out of Santiago or Lima) can save you a backtracking flight. But check pricing carefully -- open-jaws to South America aren't always cheaper than round-trips.

Watch for Error Fares

The US-Argentina route sees error fares several times a year. Sub-$400 round-trips have been spotted. Subscribe to Going (formerly Scott's Cheap Flights) and follow deal accounts on social media. When these fares appear, book immediately -- they disappear within hours.

Argentine Domestic Flights

JetSMART and Flybondi have transformed domestic Argentine travel. Flights from Buenos Aires to Mendoza, Bariloche, Iguazu Falls, and Patagonia that used to cost $200+ now start at $17-25 on budget carriers. Book these separately from your international ticket.

Common Mistakes

• Not checking Miami departures -- Even with a positioning flight, Miami routing is often cheapest overall
• Flying Saturday -- Monday departures save $184 on average
• Booking nonstop by default -- Connections save up to 12%, and the time difference is often just 2-3 hours
• Ignoring LATAM -- They're the most popular carrier for a reason, with the best South American hub network
• Buying domestic Argentine flights on your international ticket -- JetSMART and Flybondi are dramatically cheaper when booked separately
