Brazil’s antitrust authority has approved United Airlines’ plan to increase its minority stake in Azul Linhas Aéreas, clearing the way for a roughly $100 million investment tied to the Brazilian carrier’s ongoing Chapter 11 restructuring.
The Administrative Council for Economic Defense, known as CADE, approved the transaction without conditions, according to filings and company statements. The decision allows United to raise its economic interest in Azul from about 2% to nearly 8% through the purchase of newly issued shares.
The investment forms part of Azul’s broader effort to restructure its balance sheet under Chapter 11 of the US Bankruptcy Code, a process the airline entered in May 2025. Azul has continued normal flight operations throughout the restructuring while seeking to reduce debt and strengthen short-term liquidity.
As part of its Chapter 11 process, Azul plans to raise new equity through a combination of public and strategic investor offerings, including the investment by United. The proceeds are intended to support debt reduction and provide additional liquidity as the airline works toward an exit from bankruptcy protection.
United has been a minority investor in Azul since 2015 and maintains a long-standing commercial relationship with the carrier, including codeshare and cooperation agreements. The expanded stake deepens that partnership but stops well short of control, a point regulators reviewed as part of the antitrust process.
Azul is Brazil’s third-largest airline and operates a diverse fleet that reflects its hybrid business model. The carrier flies Airbus A330 widebodies on international routes, Airbus A320neo and A321neo narrowbodies on high-density domestic services, Embraer E195 and E195-E2 jets across its regional network, and ATR turboprops and Cessna Caravan aircraft serving smaller communities.
The airline has faced sustained financial pressure from dollar-denominated lease obligations, fuel costs, and currency volatility, challenges shared by much of Brazil’s airline sector in recent years. Azul’s restructuring plan includes returning a number of aircraft to lessors, renegotiating lease terms, and issuing new equity that will dilute existing shareholders.
Executives have said Azul expects to emerge from Chapter 11 in early 2026, following creditor votes and court approval of its plan. The approval of United’s expanded investment removes a key regulatory hurdle and provides further clarity around the airline’s post-restructuring ownership structure.
