Best Airlines to Fly to Buenos Aires From the U.S. (2026 Guide): Nonstop Routes, Airports & Booking Tips

Depending on where you’re flying from in the United States, getting to Buenos Aires can be delightfully simple… or a little “choose-your-own-adventure.” If you live near a major hub, you may be able to snag a nonstop flight. Otherwise, expect one connection (sometimes two), usually in the evening, because many U.S.–Buenos Aires flights are overnight.

Most nonstop routes land the next morning in Buenos Aires—perfect for starting your trip with a café con leche and a stroll through leafy Palermo. Pack an eye mask, a neck pillow, and a little patience for jet lag. Your future self will thank you.

Prefer saving money over saving time? One-stop routes via Panama City (PTY) (Copa) or other South American hubs can be a great value.

American Airlines

American is a popular choice for U.S. travelers thanks to its hub network and frequent South America service. For Buenos Aires, the two most useful gateways are:

Miami International Airport (MIA) (a classic “down-the-Americas” jumping-off point)
Dallas–Fort Worth (DFW) (handy for many central and western U.S. routes) FlightAware

Onboard, you’ll typically see a mix of Main Cabin, Premium Economy, and Flagship Business (naming can vary slightly by aircraft and schedule).

Good for: travelers who want strong hub connectivity and a solid chance at nonstop flights via MIA or DFW.

United Airlines

United’s biggest advantage for Buenos Aires is the nonstop Newark (EWR) → Buenos Aires (EZE) option—especially nice if you’re based in the Northeast (or can easily position to Newark).

Cabin options commonly include Economy, Economy Plus (extra legroom seating), Premium Plus, and United Polaris in business class on many long-haul routes.

Good for: travelers who value a straightforward nonstop from the NYC area and want a premium upgrade path. United Airlines

Delta Air Lines

Delta makes this simple: it advertises nonstop service to Buenos Aires (EZE) from Atlanta (ATL).

Atlanta is a very workable connection for a lot of the U.S.—and since ATL sits “on the way” for many itineraries heading south, it often keeps total travel time reasonable.

Cabin options commonly include Main Cabin, Comfort+, and Delta One on long-haul flights (with premium economy offerings depending on aircraft/schedule).

Good for: travelers who want a reliable connection strategy through ATL—or a nonstop if you can get yourself to Atlanta easily. Delta Air Lines

LATAM Airlines

LATAM is a major player in South America, and in big news for route-hunters, LATAM launched daily Miami (MIA) ↔ Buenos Aires (EZE) service starting December 1, 2025.

If you’re Miami-based (or can connect there cheaply), this is a very appealing way to get to Buenos Aires without adding a second stop in South America. Flight tracking listings also show active MIA–EZE operations.

Cabins typically include Economy and Premium Business (plus premium economy options depending on aircraft).

Good for: travelers who want a nonstop option out of Miami with a strong Latin America network behind it. LATAM Airlines

Aerolíneas Argentinas

Aerolíneas Argentinas offers nonstop Miami → Buenos Aires service, and it’s often a great “get me there directly” option—especially if you find a good fare or prefer flying Argentina’s flagship carrier.

Cabins are typically Economy and a business-class product often branded as Club Cóndor (availability depends on aircraft/route).

Good for: travelers prioritizing a nonstop from Miami and/or those who like pairing an international arrival with easy onward domestic connections in Argentina. aerolineas.com.ar

Copa Airlines

Copa is based in Panama City (PTY) and is famous for making Latin America surprisingly accessible with one-stop itineraries. It’s a very common “budget-friendly but still comfy” strategy for travelers from many U.S. cities: fly to PTY, connect, then continue to Buenos Aires (EZE). Copa also sells Buenos Aires fares directly on its site.

A stop in Panama can also be a fun bonus—especially if you can build in a short stopover.

Cabins are generally Economy and Business.

Good for: price shoppers and anyone who doesn’t mind (or even enjoys) a single, efficient connection. Copa Airlines

Choosing your airline

If you’re torn, here’s a friendly way to decide:

If time matters most: Start by searching nonstop routes (ATL, EWR, MIA, DFW). FlightAware
If price matters most: Check one-stop routes (especially via PTY on Copa), and be flexible by a few days. Copa Airlines
If comfort matters most: Compare premium cabins (United Polaris / Delta One / Flagship Business, etc.) and look closely at aircraft type and seat layout.

One more tip: even when two itineraries look similar, the connection can make or break your day—short layovers are stressful, and very long ones can feel like you’re living in the terminal. A “Goldilocks layover” (often 1.5–3 hours) is usually the sweet spot.

How to find the best fares (without losing your mind)

Airfare fluctuates constantly, so it pays to compare a few sources:

Skyscanner is great for scanning multiple airlines and setting price alerts. Skyscanner
Google Flights is excellent for flexible date browsing and quick comparisons.
Then, once you spot a good fare, it’s often smart to double-check the airline’s own site for seat selection, baggage clarity, and change options.
