Brazil’s antitrust regulator has given its approval for 
United Airlines to boost its investment in beleaguered carrier Azul Linhas Aereas, which is currently going through bankruptcy proceedings. The $100 million investment will increase United’s economic interest in Azul from around 2% to 8%.
The Brazilian carrier has also attracted interest from American Airlines, which has signaled its intent to make a similar investment in the airline. Since entering bankruptcy last summer, Azul’s restructuring has gathered pace, with a US court recently approving its plan to cut more than $2 billion in debt.
United Commits To $100 Million Azul Investment
Brazil’s competition authority, CADE, has greenlit United’s investment without conditions, noting that it does not pose a threat to fair competition in the Brazilian market. United already holds a small minority position in the Brazilian carrier, with the new investment set to raise this stake from 2% to approximately 8%. Azul is the third-largest airline in Brazil with an extensive network of around 150 destinations, as well as a sizable fleet of over 170 aircraft.
As reported by Poder360, Brazil’s IPS Consumo (Institute for Research and Studies of Society and Consumption) has challenged the decision, particularly the unconditional approval, arguing that it took CADE just 15 days of deliberation and left many aspects of the competition analysis unexplored. Simple Flying has reached out to United Airlines for comment on the investment approval and will update this story accordingly.
United And Azul’s History
United has been a minority investor in Azul for over a decade since its strategic partnership with the airline went live in 2014. As well as United holding a minority stake in Azul, the two carriers cooperate on codeshare routes and in other commercial areas, such as reciprocal frequent flyer benefits.
United’s interest seeks to capitalize on Azul’s strong domestic presence in Brazil, allowing UA customers to connect to a wide network of Brazilian cities. Meanwhile, Azul benefits from United’s extensive long-haul network, offering its passengers strong connectivity to the US and destinations in Asia and Europe via United hubs. Given their close relationship, United has a strong incentive to back its Brazilian partner and maintain its foothold in the country.
With Azul’s ongoing financial distress, United clearly sees value in upping its interests in the carrier at a cut-price. American Airlines clearly feels the same way and is poised to make an investment on a similar scale to United’s. However, in American’s case, the airline already holds significant ties with rival Brazilian airline GOL, complicating any potential investment in Azul.

The carrier is preparing to restructure.
Azul’s Restructuring Picks Up Pace
Like many South American airlines during the COVID pandemic, Azul faced massive financial challenges that it ultimately could not resolve. Having taken on huge debts to stay afloat, Azul also had high leasing costs and a strong reliance on the US dollar, pushing it into bankruptcy. The Brazilian carrier filed for Chapter 11 bankruptcy in New York in May 2025, with both American and United agreeing to invest upwards of $300 million in the airline’s equity.
There will also be a separate public equity offering worth around $650 million, providing Azul with much-needed equity to emerge favorably from Chapter 11. If all progresses smoothly, Azul is likely to exit bankruptcy within the first quarter of this year, with its debt to drop by around 60%. At one point, the airline considered a merger with GOL, but formally ended talks a few months ago after deciding in favor of an independent restructuring.
As per data from ch-aviation, Azul maintains a fleet of over 175 aircraft, the majority of which are narrowbody Airbus and Embraer jets. The airline also operates a small widebody fleet of ten Airbus A330s, which includes the A330-200 and A330neo, and was also a short-lived operator of two Airbus A350s before their exit from the fleet two years ago.
