Best Way to Fly to Buenos Aires From the US: Airlines, Nonstop Routes & Booking Tips (2026)

Buenos Aires is one of the most rewarding cities you can visit in South America — steakhouses, tango, grand architecture, and a nightlife scene that outlasts most people’s stamina. But first, you have to get there. And depending on where you live in the United States, your options look very different.

Some travelers can fly nonstop and land in time for breakfast. Others will connect once through a hub, usually overnight. A few budget hunters will take two stops to save a few hundred dollars. None of these approaches is wrong — they just serve different priorities. The trick is knowing which route fits yours.

This guide breaks down every nonstop option from the US to Buenos Aires, the one-stop strategies worth considering, and practical tips for finding the lowest fares without spending hours staring at flight trackers.

Nonstop Flights to Buenos Aires From the US: Your Complete 2026 Overview

All nonstop flights from the US arrive at Ministro Pistarini International Airport (EZE) — commonly called Ezeiza — which sits about 22 miles southwest of downtown. Most routes depart in the evening and arrive the following morning, which works out nicely for hitting the ground running after a café con leche.

Here’s every nonstop route currently operating between the US and Buenos Aires:

• American Airlines: Nonstop from Miami (MIA) — daily, year-round. Seasonal nonstop from Dallas–Fort Worth (DFW) and New York–JFK.
• Delta Air Lines: Nonstop from Atlanta (ATL) — daily, year-round. Seasonal nonstop from New York–JFK.
• United Airlines: Nonstop from Houston (IAH) — year-round, with double-daily service during peak season.
• LATAM Airlines: Daily nonstop from Miami (MIA) — launched December 2025.
• Aerolíneas Argentinas: Nonstop from Miami (MIA) year-round. Seasonal service from Dallas–Fort Worth (DFW).

If you’re not near any of these hubs, don’t panic. One-stop itineraries via Copa Airlines through Panama City (PTY) or Avianca through Bogotá (BOG) are solid alternatives — and often cheaper.

American Airlines: The Most Flexible US Option

American is the most versatile choice for US travelers headed to Buenos Aires. It serves EZE from three US gateways: Miami (MIA) daily year-round, plus seasonal service from Dallas–Fort Worth (DFW) and New York–JFK. Miami is the anchor — American has the highest flight frequency on the MIA–EZE route of any carrier, so schedule flexibility is real.

Cabin options span Main Cabin, Main Cabin Extra (extra legroom), Premium Economy, and Flagship Business on most long-haul aircraft. If you have AAdvantage miles to burn, this route is one of the better uses of them in the network.

• Best for: travelers flying from the Southeast, Texas, or the Northeast who want reliable nonstop service with a known US carrier
• Hub strategy: Miami is the strongest gateway — DFW and JFK routes are seasonal, so check availability carefully if you’re not flying in peak months
• Tip: MIA has an Admirals Club if you’re in Flagship Business or have lounge access — worth arriving early for a long overnight flight

Delta Air Lines: The Year-Round Atlanta Workhorse

Delta keeps things simple: daily nonstop service between Atlanta (ATL) and Buenos Aires (EZE), year-round. Atlanta is a massive connecting hub, which means a huge portion of the US can reach EZE with just one connection to ATL — and many itineraries from the Southeast and Midwest are single-connection at worst.

Delta also runs seasonal nonstop service from New York–JFK, operated on the Airbus A330-900neo with Delta One Suites in business class. If you’re a premium traveler flying JFK, this is one of the finer long-haul experiences available on this route.

• Best for: travelers within easy reach of ATL, or Northeast flyers looking for a premium business-class experience out of JFK
• Cabin options: Main Cabin, Comfort+, Premium Select, and Delta One (lie-flat in business on most aircraft)
• Tip: The ATL–EZE year-round schedule is your most reliable fallback if other nonstop routes are sold out or overpriced

United Airlines: Seasonal Nonstop From Houston

United flies nonstop year-round from Houston’s George Bush Intercontinental Airport (IAH) to Buenos Aires EZE. Frequency picks up during peak season — you’ll sometimes find double-daily departures in summer and around the holidays — and drops to a single daily or near-daily during quieter months. Either way, IAH is a massive hub, so reaching it from most parts of the US takes just one connection.

• Best for: Texas-based travelers and those who prefer United’s MileagePlus program for long-haul redemptions
• Cabin options: Economy, Economy Plus, Premium Plus, and United Polaris (lie-flat business class)
• Tip: United typically operates the Boeing 777-200 on this route — a solid long-haul aircraft with decent premium cabin options

LATAM Airlines: A Strong New Nonstop From Miami

LATAM launched daily nonstop service between Miami (MIA) and Buenos Aires (EZE) in December 2025, and it’s a real addition to the route map. LATAM is the dominant carrier across South America, which means excellent onward connections within Argentina and to neighboring countries if your trip extends beyond Buenos Aires.

If you’re Miami-based — or can position there cheaply — this is a clean way to get to EZE without adding a South American stopover. Cabin options typically include Economy and Premium Business depending on aircraft.

• Best for: Miami-area travelers and those with onward plans in South America who want LATAM’s regional network
• Tip: Compare LATAM’s fares directly at latamairlines.com — they sometimes run better prices than aggregators

Aerolíneas Argentinas: Flying Argentina’s National Carrier

Aerolíneas Argentinas offers nonstop Miami–Buenos Aires service year-round, plus seasonal flights from Dallas–Fort Worth. As Argentina’s flag carrier, they’re strongly focused on this route — frequency is solid and the cabin product is dependable, with Economy and Club Cóndor (business class) available.

One practical perk: if you’re planning to travel within Argentina after landing (Patagonia, Iguazú Falls, wine country in Mendoza), Aerolíneas has the most extensive domestic network in the country. Arriving on Aerolíneas can make connecting to domestic flights easier.

• Best for: Miami-area travelers and anyone planning domestic Argentina travel after arriving in Buenos Aires
• Tip: Book domestic Argentina flights through Aerolíneas early — capacity on popular routes like EZE–USH (Ushuaia) fills up faster than you’d expect

Copa Airlines: The Smart One-Stop Strategy

Copa doesn’t fly nonstop to Buenos Aires — its hub is Panama City (PTY) — but don’t dismiss it. Copa’s model is built around making Latin America accessible with a single efficient connection, and PTY is one of the smoother connecting airports in the region. From most US cities, you fly to PTY and continue south to EZE.

The appeal is price. Copa often comes in cheaper than the major US carriers on this route, and the product is comfortable without being budget-airline spartan. Business class is available on many Copa routes too.

• Best for: budget-conscious travelers, those flying from smaller US cities without direct access to nonstop hubs, and anyone who doesn’t mind one stop
• Tip: PTY connections can be tight — aim for at least 90 minutes of layover time to avoid stress if your inbound flight runs late

How to Find the Best Fares on Flights to Buenos Aires

Buenos Aires airfare moves around a lot. The gap between booking smart and booking carelessly can easily be $300–$500 on a round trip. A few approaches that actually work:

• Book 6–10 weeks out for the best balance of seat availability and price. Last-minute fares to EZE spike sharply.
• Use Google Flights for date flexibility — the calendar view shows which days are cheapest over a multi-week window. Shifting your departure by two or three days can save real money.
• Check Skyscanner for multi-airline comparisons — it surfaces options that Google sometimes misses, especially on one-stop itineraries with budget South American carriers.
• Go directly to airline sites once you’ve spotted a price — airlines often match the aggregator price and give you better seat selection, clearer baggage policies, and easier changes.
• Travel in shoulder season — Buenos Aires is in the Southern Hemisphere, so its peak summer (December–February) is US winter. Traveling in the US summer (BA’s winter, June–August) can mean lower fares and fewer tourists, though cooler weather.

One more thing worth knowing: the “Goldilocks layover” for Buenos Aires-bound connections is usually 90 minutes to 3 hours. Under 90 feels rushed; over 4 hours and you’re doing unnecessary time in a terminal.

Frequently Asked Questions

What is the best airline to fly to Buenos Aires from the US?

For most travelers, American Airlines or Delta are the top picks — both offer nonstop flights from major hubs (Miami and Atlanta, respectively) on reliable year-round schedules. If price is your main concern, Copa Airlines via Panama City often comes in cheaper. If you’re based in Miami, LATAM and Aerolíneas Argentinas are both solid nonstop options worth comparing.

How long is the flight from the US to Buenos Aires?

Nonstop flights from Miami run roughly 8.5 to 9 hours. From Atlanta, expect around 10 hours. From Houston or Dallas, flights are in the 10–11 hour range depending on routing. Most depart in the evening and arrive the next morning, which works well for hitting the ground with a full day ahead of you.

Which airport should I fly into for Buenos Aires?

Almost all US flights land at Ministro Pistarini International Airport (EZE) — also called Ezeiza — which is the main international gateway. It sits about 22 miles from the city center, so plan for 45–60 minutes by taxi or pre-arranged transfer depending on traffic. The other Buenos Aires airport, Aeroparque Jorge Newbery (AEP), handles mostly domestic and some regional flights and is much closer to the city.

Are there direct flights from New York to Buenos Aires?

Yes — both American Airlines and Delta operate seasonal nonstop service from New York–JFK to Buenos Aires (EZE). American also connects from Newark (EWR) and JFK with one stop. If nonstop isn’t available on your travel dates, connecting through Miami, Atlanta, or Houston are all efficient paths.

What’s the cheapest time of year to fly to Buenos Aires?

The lowest fares typically appear in the US summer months — June through August — which is Buenos Aires’s winter. Temperatures drop but rarely get severe. You’ll find fewer tourists, lower hotel rates, and the city still fully alive. Avoid peak Argentine summer (December–January) if you’re watching your budget, as this is both expensive and busy.

Do I need a visa to fly to Buenos Aires from the US?

US citizens do not need a visa to enter Argentina for tourism stays up to 90 days. You’ll need a valid US passport. Entry requirements can change, so always verify current rules through the Argentine consulate or the US State Department before you travel.

Final Thoughts

There’s no single “best” way to fly to Buenos Aires from the US — it comes down to where you’re starting, what you’re willing to spend, and how much you value a nonstop. If you can get to Miami, Atlanta, or Houston, you have genuine nonstop options. If not, a single connection via Panama City or another South American hub is easy, efficient, and often cheaper.

Start by searching your dates on Google Flights with the calendar view, spot the cheapest window, then check the airline’s own site before booking. That two-step process alone will save most travelers money. Once you’ve landed, Buenos Aires rewards the effort — and then some.
