Argentina is one of the longest countries on the planet. Hence, if you want to know the country well, taking domestic flights is certainly the best way to get around the country.

Here we’ve put together everything you’ll need from the leading Argentine domestic flight airlines, plus some expert tips on how to save money on every flight.

One of the main reasons why Argentine domestic flights have become cheaper is competition brought by deregulation, plus there are now more routes than ever. Flying across this amazing country has never been so affordable. Let’s dive in.

The Airlines You Need to Know

Three carriers dominate domestic air travel in Argentina: Aerolíneas Argentinas, JetSMART, and Flybondi. Each serves a different type of traveller, and knowing the difference matters.

Aerolíneas Argentinas

Aerolíneas Argentinas is the national airline of Argentina and by far the most comprehensive choice since it covers over 39 destinations and has the largest domestic route network in Argentina. A majority of standard fares already include 15 kg of checked luggage and advance seat selection, thus offering a very good value when compared to the prices that budget airlines usually charge for these services. Moreover, it is the most reliable one of all since it has the lowest rate of cancellations, which is an important consideration especially when your travel depends on timing.

JetSMART and Flybondi

Argentina’s two budget airlines are these. JetSMART lies more on the reliable side, being one that has considerably increased its route network in 2025, and it always offers lower base fares, especially on high-traffic routes like Buenos Aires, Mendoza, and Tucumán. Flybondi often has the lowest advertised price,s though it experiences more delays historically. With both, keep in mind that base fares do notalways  include luggage; always figure out your total cost before hitting ‘book.’ 

Top Domestic Flight Routes in Argentina

You’ll almost always depart from Aeroparque Jorge Newbery (AEP) in Buenos Aires for domestic travel — it’s centrally located and manageable. Here are the routes that should be on your radar.

Buenos Aires to Bariloche

A flight of roughly two hours from Buenos Aires to Bariloche takes you to the Lake District of Argentina that is known for its gorgeous glacial lakes, ski slopes, and chocolate shops. A bus trip between these two places, however, lasts more than 20 hours. All three carriers compete on this route, so there are plenty of cheap options for travelers in the country.

Buenos Aires to Iguazú and Mendoza

A flight from Buenos Aires to Puerto Iguazú can get you close to the famous UNESCO World Heritage waterfalls in less than 2.5 hours, while it would take some 18 hours by road. On the other hand, flying from Buenos Aires to Mendoza (just about 1 hour and 50 minutes) will open the door to Argentina’s globally acclaimed Malbec wine region, where you will have the Andes as your scenery. Both flights are quite competitive, and if you book early, you can often get a good deal on these Argentina flights.

Buenos Aires to Ushuaia and Salta

If you’re chasing Patagonia, the Buenos Aires to Ushuaia flight (roughly 3 hours) is non-negotiable — overland takes days. Equally, the Buenos Aires to Salta flight puts you in Argentina’s culture-rich northwest in under two hours, opening up the Quebrada de Humahuaca and colonial architecture that most visitors miss entirely.

What to Expect: Domestic Flight Prices in Argentina

On low-cost airlines in Argentina, one-way fares on popular routes can start from $30–$60 USD when booked in advance. Aerolíneas Argentinas typically starts from $80–$150 USD for non-residents on the same routes, though this often includes luggage that budget carriers charge extra for. For longer hauls like Buenos Aires to Ushuaia, expect round-trip prices of $150–$300+ USD depending on timing.

Prices spike sharply during Argentine peak periods — December to February, Easter week, and July school holidays. During these windows, last-minute domestic airfare in Argentina is rare and expensive. Book months ahead if your travel falls during these times. Shoulder seasons (April–June and August–November) offer the most affordable domestic flight tickets Argentina with far better availability.

How to Book Domestic Flights in Argentina on Booking.com

Search and Compare in One Place

Head to the Flights tab on Booking.com and enter your route. For most Argentina domestic flights, select Buenos Aires (AEP) as your departure point. Use the flexible dates feature to view prices across multiple days — this alone can reveal significantly cheaper options if your schedule has any wiggle room.

Use Multi-City Search for Complex Itineraries

Planning to visit Bariloche, Mendoza, and Iguazú in one trip? The multi-city flight search lets you plan up to five flights simultaneously and generates complete itineraries with layover details. It’s one of the most useful tools for building a multi-destination Argentina travel plan without jumping between multiple airline websites.

Bundle Flights with Hotels

One of the biggest advantages of using Booking.com for Argentina flights is the ability to bundle your accommodation at the same time. Genius loyalty members get access to exclusive rates, making the total cost of your trip meaningfully lower when you book everything together.

Pro Tips for Getting the Best Deals

Booking 6–10 weeks ahead (or 3–6 months during peak season) is the most reliable way to get cheap flights within Argentina. Mid-week departures — especially Tuesdays and Wednesdays — consistently price lower than weekend flights. Early morning and late evening slots are also cheaper than convenient daytime options.

Always calculate the total cost of your Argentina domestic flight, including baggage, not just the base fare. A $35 budget airline ticket can easily become $90+ once you add carry-on luggage and seat selection. Aerolíneas Argentinas often wins on total value when bags are factored in. Also, carry your passport at all times — foreign visitors cannot use a driver’s licence for domestic flights in Argentina, only a passport.

Conclusion

Argentine domestic flights are the only feasible way to get the most out of this country’s amazing diversity. The flight is not just a convenience, but a must to reach the most emblematic destinations of the country, such as the wine valleys of Mendoza or the glaciers of El Calafate, which are separated by very long distances. Due to real market competition, domestic flights in Argentina have gotten cheaper and are more available than before.

Booking.com will allow you to check at a glance worldwide offers of different airlines, plus if you get a flight ticket and accommodation together, you will save even more, and making your reservation earlier will get you the best airfare deals in Argentina before the prices go up. Be smart, schedule your first flight, and among the wonderful things you will bring back with you from Argentina will be one of the best travel memories of your life.
