Brazil, Chile, Argentina, Paraguay Sign ALAS Skies Deal

Launching the Single South American Sky

Brazil, Argentina, Chile, and Paraguay have formally initiated a landmark effort to integrate regional airspace by signing a memorandum of understanding in Asunción. This initiative, known as the ALAS (Air Liberalization for the Development of a Single South American Sky), aims to create a Single South American Sky by harmonizing regulatory frameworks across the four nations. The official press release from DINAC confirms that this agreement establishes a formal roadmap for the progressive liberalization of air traffic rights.

The agreement marks a significant shift in the South American aviation market, which handled a combined total of nearly 190 million passengers in 2025, with Brazil alone accounting for 130 million. By moving toward a model similar to the European Union's integrated framework, the signatory countries seek to reduce operational barriers and foster greater connectivity between cities across the continent.

Regulatory Harmonization and Implementation

The participating aviation authorities—including the ANAC (Agência Nacional de Aviação Civil) of Brazil and Argentina, Chile's DGAC (Dirección General de Aeronáutica Civil), and Paraguay's DINAC (Dirección Nacional de Aeronáutica Civil)—have established a dedicated working group. This group has a mandate to develop a comprehensive proposal for regulatory convergence and the implementation of the single market within a 12-month period.

This move follows a trend of open skies in Latin America, accelerated by Argentina's recent domestic deregulation under Decree 599/2024. The ALAS agreement is designed to supersede earlier, more limited attempts at integration, such as the 1996 Fortaleza Agreement, which failed to fully address bilateral route restrictions. The long-term objective of the ALAS framework is to achieve full cabotage, allowing carriers from one member state to operate domestic flights within the borders of another.

Industry and Stakeholder Impact

For major South American airlines such as LATAM, Gol, Azul, and JetSMART, the agreement offers the potential for expanded operating freedoms. If successful, carriers could theoretically operate domestic routes in neighboring countries without the need to establish separate local subsidiaries, significantly reducing administrative overhead.

However, the path to full implementation may face challenges. According to aviation industry labor analysts, domestic aviation unions may resist specific provisions, particularly those that could permit foreign crews to operate domestic flights. Despite these potential hurdles, the Brazilian Minister of Ports and Airports, Tomé Franca, emphasized that the agreement is a critical first step toward creating more connected cities throughout South America.

Technical Analysis: The Path to Liberalization

The ALAS agreement represents a structural shift from bilateralism to a multilateral regulatory regime. Historically, the European Union’s single aviation market in the 1990s served as the gold standard for this transition, resulting in full deregulation and the rise of low-cost carriers across the bloc. While the ALAS initiative is in its infancy, the 12-month timeline for the working group suggests an aggressive push for integration. The success of this model will depend on the ability of ANAC, DGAC, and DINAC to reconcile disparate safety standards and operational requirements. If the working group successfully presents its implementation plan by July 2027, the region will likely see a surge in competitive activity, potentially lowering fares for passengers as new direct routes between secondary cities become economically viable.

Next Steps: The 12-Month Roadmap

The ALAS working group is now tasked with drafting the legal and technical framework required to support this single market. The following milestones represent the current trajectory for the agreement:

• July 2027: The ALAS Working Group is expected to present its formal proposal for the harmonized regulatory framework and progressive implementation schedule.
• 2026–2027: Uruguay is expected to pursue accession to the ALAS agreement, further expanding the scope of the integrated market.

Why This Matters for Regional Connectivity

For the South American aviation sector, the ALAS agreement signals a move toward a more efficient, competitive landscape that could redefine how airlines approach network planning. By eliminating the current patchwork of bilateral restrictions, the deal positions the region to capture higher passenger volumes and stimulate economic activity through enhanced mobility. For passengers, the ultimate outcome of this regulatory shift is expected to be improved access to affordable air travel and a wider range of direct flight options between the participating nations.
