- Brazil, Argentina, Chile and Paraguay initiated Single South American Sky
- The four nations signed an ALAS memorandum of understanding
- The long-term goal is full cabotage
- A 12-month window covers common regulatory standards
- Uruguay is expected to join next
Brazil, Argentina, Chile and Paraguay have initiated the creation of a unified regional aviation market known as the Single South American Sky. The four nations signed a memorandum of understanding under the framework named ALAS, Air Liberalisation for the Development of a Single South American Sky. The model draws from the European Union’s single aviation market and seeks to progressively eliminate national barriers to passenger and cargo traffic.
The long-term goal is full cabotage, which permits an airline based in one country to operate domestic flight routes within any of the other participating nations. The aviation authorities gave themselves a 12-month window to establish common regulatory, technical and safety standards. The market remains open for other neighbouring countries to join, with Uruguay expected to be next in line.
By reducing regulatory roadblocks and encouraging seventh-freedom traffic rights, the four nations aim to boost regional connectivity, invite new low-cost competition and lower airfares for travellers across South America.
