LATAM, GOL, and Azul see 168 flights disrupted across Brazil

Disruption overview

Brazil's busiest airports were disrupted on 18 May 2026 after severe weather, congestion, and operational pressure forced airlines to trim schedules. A total of 25 flights were canceled and 143 were delayed at São Paulo-Guarulhos, Rio de Janeiro/Galeão, Viracopos, and Tancredo Neves, with LATAM Brasil, GOL Linhas Aéreas, Azul Brazilian Airlines, Azul Conecta, American Airlines, and United Airlines all affected. Because weather appears to have been the main driver, compensation is usually unlikely, but airlines should still provide care such as rebooking or refunds, meals, communication, and accommodation when needed.

Disruption details

Brazil's busiest airports were hit by widespread disruption on 18 May 2026, when operations at São Paulo-Guarulhos International Airport, Rio de Janeiro/Galeão International Airport, Viracopos International Airport, and Tancredo Neves International Airport were scaled back after severe weather, heavy traffic, and gate-capacity bottlenecks put pressure on the network. A total of 25 flights were canceled and 143 flights were delayed.

For passengers, this meant departure boards changing throughout the day, long customer-service lines, missed onward connections, and in some cases overnight uncertainty. The disruption affected both domestic and international travel, leaving thousands of travelers waiting across terminals in São Paulo, Rio de Janeiro, Campinas, and Belo Horizonte.

The heaviest operational pressure fell on Brazil's main hubs, especially São Paulo-Guarulhos:

• São Paulo-Guarulhos recorded 7 cancellations and 107 delays.

• Tancredo Neves in Belo Horizonte saw 8 cancellations.

• Viracopos in Campinas had 6 cancellations.

• Rio de Janeiro/Galeão logged 4 cancellations and 9 delays.

Among the airlines, LATAM Brasil carried the biggest delay burden, canceling 5 flights and delaying 67 at its GRU hub. GOL Linhas Aéreas canceled 2 services and recorded 49 delays across GRU and GIG.

Azul Brazilian Airlines lost 13 flights and delayed 26 more at CNF, VCP, and GIG, while Azul Conecta canceled 3 flights and logged 1 delay. American Airlines also canceled 1 flight from GRU, and United Airlines canceled 1 service from GIG.

Once the first delays started building, recovery was difficult. Brazil's dense point-to-point network relies on tight aircraft rotations, so smaller setbacks at the main airports quickly turned into wider knock-on disruption later in the day.

Airport authorities linked the disruption to severe weather patterns, runway congestion, and traffic-flow management directives that forced carriers to trim schedules for safety. At the same time, unexpected crew-roster gaps and overlapping maintenance inspections left airlines with less flexibility to absorb the shock.

Airlines spent the day rebooking customers, arranging overnight hotel stays, and rerouting baggage. By early evening on 18 May, operations were still stabilizing, and dispatch managers expected schedules to normalize within the next 24 hours, although more bad weather or further staffing shortfalls could delay that recovery.

If your flight was affected, it's understandable to feel frustrated. Because this disruption appears to have been driven mainly by severe weather and wider air traffic restrictions, compensation is usually unlikely.

Although compensation is unlikely here, that doesn't mean you're without support. Under ANAC 400, airlines should still provide care and assistance during major disruption, including rebooking or refunds, food and refreshments during longer waits, help with communication, and accommodation if you need to stay overnight.
