Brazil and Neighbors Sign a Deal for South America’s Open Skies

Aviation

The South America open skies push took a concrete first step this week. Four countries signed up to a plan that could one day let airlines fly freely across the region.

Brazil, Argentina, Chile and Paraguay signed the memorandum in Asunción. Brazil was represented by officials from its aviation authorities.

The framework has a fitting name. It is called ALAS, which means wings, and stands for Air Liberalization for the Development of a Single South American Sky.

The document is a starting point, not a finished market. It sets up a working group with up to a year to draft the common rules that would make integration real.

What South America open skies would change

The model is European. Officials point to the European Union’s single aviation market, where a carrier from one member can fly routes across the bloc.

Applied here, it would open borders both ways. A Brazilian airline could operate in a neighbour’s market, and foreign carriers could fly domestic routes inside Brazil, under reciprocal deals.

It could go further still. The plan envisions letting an airline fly between two foreign countries without touching its home base, a freedom now largely limited to cargo.

The working agenda is technical but concrete. It covers harmonising rules, recognising each other’s licences and certificates, easing operations and aligning passenger rights.

A concrete example makes it real. Under the vision, a Brazilian carrier could one day fly Buenos Aires to Lima without the trip starting or ending in Brazil.

The signing came with a side deal. Brazil and Paraguay also signed a bilateral memorandum on air services, alongside meetings of the four delegations.

Why it matters for travellers and airlines

The stated goal is more choice. By widening where airlines can fly, the governments hope to boost competition, add flights and open new routes.

Underserved regions are a focus. Smaller cities that big carriers skip could gain service if rivals find it easier to operate across borders.

The timing fits a busy market. Brazil’s aviation sector has grown fast, and regional carriers are consolidating and expanding routes across the continent.

Brazil is also updating its own rulebook. Its ports and airports ministry plans to refresh the guidelines it uses to negotiate air-service agreements between governments.

Those agreements are the legal plumbing. They set the terms under which airlines can fly international routes, so clearer rules can speed new connections.

It also sits within a wider drive. The move follows deeper regional integration, from the trade bloc Mercosur to earlier open-skies deals among smaller neighbours.

Our reporting has shown this is not a sudden pivot but the latest chapter in a long regional push. Brazil and Argentina have been expanding bilateral flight rights since at least 2019, when they raised the weekly flight cap from 133 to 170 and eliminated cargo limits. A landmark Brazil-Argentina open skies agreement followed in 2024, and Argentina has led broader liberalization efforts alongside Paraguay, Uruguay, Chile, Peru, Ecuador, Panama and Canada. The ALAS framework builds directly on that foundation, extending the ambition from bilateral deals toward a unified multilateral market.

Caution is still warranted. Each country keeps its own laws, so the rollout will be gradual and the final shape depends on the coming negotiations.

For a traveller or investor, the read is promising but patient. Open skies tends to lower fares and widen networks over time, though the benefits here are a few years off.

The bigger prize is scale. A continent that moves people as freely as goods would knit its economies closer, turning distant capitals into easier day trips.

What is the South America open skies agreement?

It is a memorandum signed by Brazil, Argentina, Chile and Paraguay to build a single South American aviation market, known as ALAS. It sets up a working group with up to a year to draft common rules, modelled on the European Union’s aviation market.

How would it affect flights and fares?

By letting airlines operate more freely across borders, it aims to boost competition, add flights and open new routes, especially to underserved cities. Open-skies frameworks tend to lower fares over time, though the effect would be gradual.

When would it take effect?

Not immediately, since the memorandum only starts a process. It gives a working group up to twelve months to draft the rules, after which each country must implement them under its own laws, so the benefits are likely years away.

What is the immediate next step for this agreement?

A working group has been established and given up to 12 months to draft the common rules. This document is a starting point, not a finished market.

What are the goals of this open skies push?

The goal is to create more competition, more flights and new routes, especially to underserved areas. This could reshape fares and connectivity across the continent.
