Brazil’s competition authority, Administrative Council for Economic Defense (CADE), has launched formal administrative proceedings to investigate alleged anti-competitive conduct in the domestic passenger air travel market involving Gol Linhas Aéreas and LATAM Airlines. The case centers on suspected price fixing on commercially domestic routes.
The investigation follows a preliminary inquiry initiated in 2023 by CADE’s General Superintendence, which examined pricing behavior in Brazil’s airline sector using advanced data analytics and market-monitoring techniques developed by the agency’s Project Brain team. According to the authority, the inquiry uncovered evidence of a persistent pattern of interdependence in fare movements between Gol and Latam, raising concerns that the airlines’ pricing conduct may extend beyond normal competitive dynamics.
CADE’s review focused in particular on whether the observed pricing patterns reflected tacit coordination facilitated by algorithmic pricing systems and shared market data rather than independent business decisions. The authority assessed contracts between the airlines and third-party providers of fare intelligence, pricing analytics, content distribution, and dynamic pricing services, concluding that these tools may create opportunities for the exchange of commercially sensitive information and reduce uncertainty between competitors.
The General Superintendence emphasized that the risks are heightened in concentrated and transparent markets such as Brazil’s domestic aviation sector, where algorithmic pricing tools and common data infrastructures can make it easier for firms to align pricing strategies without explicit communication. The case reflects growing antitrust scrutiny worldwide over the role of algorithms and shared digital tools in potentially enabling coordinated conduct.
The opening of administrative proceedings does not constitute a finding of wrongdoing. Gol and Latam will now be formally notified and given the opportunity to submit their defenses and supporting evidence. The investigation will proceed under Brazil’s Competition Law, with the final determination to be made by the CADE Tribunal after a full review of the evidence.
The case could become a test of how competition authorities address allegations of algorithm-assisted coordination in concentrated markets, particularly in sectors where pricing is increasingly driven by automated and data-intensive systems. If CADE ultimately finds an infringement, the decision may have implications well beyond Brazil’s aviation sector, adding to the broader global debate over the antitrust risks posed by algorithmic pricing technologies.
