Thousands of travelers across Chile, Colombia, and Brazil began their weekend with confusion and frustration as LATAM Airlines and Avianca faced major operational breakdowns. A combined 31 flight cancellations and many more delays hit three of the region’s busiest hubs, creating a ripple effect felt throughout South America’s aviation network.
Airports in Santiago, Medellín, and São Paulo reported long queues, limited flight availability, and overcrowded terminals. With airlines struggling to rebook stranded passengers, many travelers found themselves sleeping in terminals or searching for last-minute alternatives.
The incident highlights how even small disruptions can escalate quickly across interconnected regional routes.
Airports Most Affected
Santiago – Comodoro Arturo Merino Benítez International Airport
Chile’s main gateway saw the worst impact. LATAM recorded 23 cancellations and 14 delays, the highest volume among the affected carriers. The airline handles a major share of flights in and out of Santiago, making the disruption felt widely.
The surge in grounded flights created long queues at rebooking counters. Several travelers reported waiting hours before receiving updates on alternative flights.
Medellín – José María Córdova International Airport
In Colombia, Avianca canceled 4 flights and delayed 22 more. While the percentage of canceled flights remained small, the passenger experience suffered because Medellín’s airport often operates near capacity during peak hours.
Travelers reported slow communication and difficulty accessing real-time updates through the airline’s app, creating more uncertainty.
São Paulo – Congonhas Airport
LATAM Brasil faced 4 cancellations and 9 delays at one of Brazil’s most important domestic hubs. Congonhas, known for high-frequency short-haul routes, felt immediate congestion due to the tight scheduling of flights. Even minor disruptions can quickly snowball at this airport.
Airlines Facing Operational Pressure
LATAM Airlines
LATAM experienced the largest disruption, especially in Santiago. As one of South America’s biggest carriers, any interruption to LATAM’s network affects multiple connecting cities. The airline issued general statements assuring passengers of ongoing efforts to stabilize schedules but offered limited real-time assistance.
Avianca
Avianca, Colombia’s flagship airline, faced fewer cancellations but struggled with delays. Bogotá and Medellín serve as major transit points, so even small operational issues can impact onward journeys to Central America, the Caribbean, and the United States.
LATAM Brasil
The Brazilian subsidiary, which focuses mainly on domestic operations, encountered fewer cancellations overall. However, the timing of the interruptions caused congestion across already-busy morning and evening travel windows.
Why the Disruptions Escalated
South America’s aviation system often operates close to capacity, especially on popular routes connecting major hubs. A single delay can affect aircraft rotations, crew availability, and gate assignments.
Industry experts note that seasonal travel peaks, weather shifts, and technical checks can compound issues. Even though each airline canceled only a fraction of scheduled flights, the concentrated impact on three high-traffic airports triggered region-wide congestion.
Passengers also reported difficulty reaching customer service agents and limited information from airport displays. Many resorted to social media and word-of-mouth updates.
Regional Impact on Travelers
The ripple effect reached beyond the three affected cities. Travelers connecting through Lima, Bogotá, Rio de Janeiro, and Buenos Aires faced rebookings or significant schedule changes.
Tourism operators in Chile and Colombia noted an uptick in last-minute cancellations of tours, hotel stays, and regional transfers. Business travelers missed meetings, and families on holiday struggled to rearrange booked itineraries.
Local authorities at each airport activated crowd-management protocols to reduce congestion, offer seating space, and coordinate with airlines to help stranded passengers. Despite these efforts, many waited hours in lines.
What Travelers Should Do During Large-Scale Disruptions
Flight cancellations can be stressful. Taking the right steps can make rebooking easier and reduce uncertainty.
1. Check for Real-Time Updates
Monitor your phone, email, and the airline’s app. Airlines often push rebooking notices digitally before announcing them at the airport.
2. Visit Airline Counters Early
Early arrival at service desks improves your chances of securing seats on next-available flights. Lines become long within minutes during mass cancellations.
3. Know Your Airline Rights
Each country has its own passenger protection rules. Many airlines offer hotel accommodation, meal vouchers, or refunds when disruptions are within their control.
4. Explore Alternative Routes
Indirect flights or nearby airports may help you reach your destination faster. In cities like São Paulo or Bogotá, alternative airports are often within reach.
5. Keep Essential Documents Handy
Ensure passports, IDs, tickets, and payment cards remain accessible. This speeds up rebooking and emergency arrangements.
A Reminder of Air Travel Vulnerability
The recent wave of cancellations across Santiago, Medellín, and São Paulo shows how fragile flight schedules can be. With airlines stretched by demand, even minor operational problems can lead to widespread disruption.
While Avianca, LATAM, and LATAM Brasil work to restore stability, the impact on travelers remains significant. The episode also stresses the need for clearer communication, stronger passenger support, and improved contingency planning across South America’s aviation network.
Travelers across the region now hope the airlines resolve their operational issues quickly to avoid a repeat during the upcoming holiday travel rush.
