Six countries have joined a framework aimed at building a more integrated aviation market, while new bilateral seventh-freedom agreements are beginning to expand airline operating options across the region.
South America has taken a significant step toward deeper aviation integration. Argentina, Bolivia, Brazil, Chile, Paraguay and Uruguay now participate in the South American Air Liberalization Agreement, known as ALAS, which is intended to support the gradual development of a more open regional aviation market.
The initiative could eventually reduce regulatory barriers, align national frameworks and give airlines greater flexibility to operate across borders. Its immediate impact, however, is more limited than the concept of a “Single South American Sky” might suggest.
ALAS does not yet give carriers unrestricted access to all six participating markets. For now, the most concrete changes come from separate bilateral agreements granting seventh-freedom traffic rights between selected countries.
A regional ambition built through bilateral agreements
Argentina, Brazil, Chile and Paraguay launched ALAS in Asunción on July 14, 2026. Bolivia and Uruguay joined the initiative on July 22, bringing the number of participating countries to six.
The agreement creates a working group of national aviation authorities, which has up to 12 months to prepare proposals for the gradual implementation of a more integrated market. Its work will cover regulatory harmonisation, mutual recognition of licences and certificates, passenger rights, environmental sustainability, and airport and air navigation infrastructure.
That process will take time. The participating countries retain their own legal and regulatory frameworks, and ALAS has not yet established a common market-access regime comparable to the one operating within the European Union.
More immediate progress is being made through bilateral arrangements.
Brazil signed memoranda with Argentina and Paraguay incorporating seventh-freedom rights for passenger, cargo and mixed services. According to the Brazilian government, those provisions took immediate effect while the underlying air service agreements proceed through the formal legal processes required for their amendment.
Uruguay and Brazil subsequently agreed to reciprocal rights extending up to the seventh freedom for passenger services. Uruguay and Bolivia also signed a framework covering passenger and cargo operations, including scheduled and non-scheduled flights.
These agreements demonstrate that the liberalisation process is beginning to produce operational tools. They do not, however, create a single multilateral system under which every airline from an ALAS country can automatically operate between any two participating markets.
Why seventh-freedom rights matter
Seventh-freedom rights allow an airline to operate between two foreign countries without the service beginning or ending in its home country.
A carrier could therefore position aircraft outside its domestic market and use them to operate international routes between other countries, provided that the necessary rights and authorisations have been granted by the states concerned.
This can give airlines greater flexibility in fleet deployment and network planning. Instead of connecting every international operation to a national hub, a carrier could potentially establish a foreign operating base, build multi-country rotations or serve cross-border markets that do not fit its traditional network structure.
The rights could also create opportunities between secondary cities. Many journeys within South America still require passengers to connect through a major capital or hub, even when the origin and destination are relatively close geographically.
A more flexible framework could allow airlines to design services around passenger demand rather than the nationality of the carrier. It could also help operators add seasonal capacity or test routes without restructuring their entire home-market network.
The market context is favourable. Air traffic to, from and within Latin America and the Caribbean reached 477.3 million passengers in 2025, an increase of 3.8%. Domestic and intraregional operations generated 84% of the year’s net growth.
Brazil–Argentina traffic rose by 29.7%, while Argentina recorded the highest percentage growth among the region’s major aviation markets. These figures suggest that demand between neighbouring countries is already an important source of expansion.
Regulatory access is only part of the equation
New traffic rights do not automatically result in new routes.
Airlines must still determine whether demand, fares and expected load factors can support an operation. Airport charges, taxation, ground-handling costs, slot availability and access to aircraft will also influence whether a route is commercially viable.
Designated carriers will remain subject to national operating approvals and applicable safety, ownership and regulatory-control requirements. In practice, the value of seventh-freedom rights will depend on whether countries can make the authorisation process sufficiently clear and predictable.
The framework may be particularly relevant for air cargo.
Freight demand does not always produce balanced return flows between two markets. Greater freedom to operate multi-country rotations could allow cargo airlines to move agricultural products, perishables, industrial components and e-commerce shipments more efficiently, while reducing empty positioning sectors.
But cargo operators will face their own constraints, including customs procedures, airport opening hours, warehouse capacity, ground infrastructure and the availability of sufficient freight volumes.
The same principle applies to passenger operations: liberalisation creates the regulatory possibility, but it does not replace the commercial case.
A new competitive question for airports
Airports will also need to consider how ALAS could reshape competition for airline activity.
If carriers gain more freedom to position aircraft outside their home countries, airports may have new opportunities to attract regional bases, seasonal services, cargo operations and aircraft overnighting.
This could benefit airports outside the largest national hubs, particularly where cross-border demand exists but current connectivity remains limited.
Success will depend on more than traffic rights. Airports will need competitive charges, available capacity, efficient border processing, reliable ground handling and services capable of supporting airline operations.
For airport operators and territorial authorities, ALAS may therefore create an opportunity to reassess which markets they can realistically serve and how they present their infrastructure to carriers.
The next 12 months will test the project
ALAS is an important political signal. Six South American countries have agreed to examine how deeper aviation integration could improve connectivity, competition and economic exchange.
The first bilateral seventh-freedom agreements show that the initiative is moving beyond declarations. Yet the more complex work remains ahead.
National authorities must determine how to align regulations, recognise licences and certificates, protect passengers and oversee competition while maintaining effective safety and regulatory control.
The European market may provide inspiration, but South America does not have an equivalent supranational legal and institutional structure. Its integration model will therefore need to be built through negotiation between sovereign states and implemented progressively.
The next 12 months will show whether ALAS remains primarily a cooperation framework or begins to develop into a market architecture that airlines can use at scale.
Traffic rights have opened the door. Airlines, airports and regulators must now determine whether there is a sustainable market on the other side.
