Miami joins cities like New York, Atlanta, Dallas, and Houston in facing major flight delays to São Paulo, Bogotá, Rio de Janeiro, and Santiago due to the Venezuelan airspace shutdown, disrupting travel between the US and South America, including Brazil, Argentina, Colombia, and Chile. The ongoing closure of Venezuelan airspace, a consequence of the military conflict in the region, has forced airlines to implement extensive rerouting strategies for flights heading to these key destinations. As a result, passengers are experiencing longer travel times, increased delays, and operational challenges. Airlines are struggling to adjust flight schedules, fuel management, and crew timings, which is impacting not only international travel but also connecting flights within South America.

Airline Disruptions: Ripple Effect from Military Action and New Travel Ban

As of January 4, 2026, US airlines are grappling with major disruptions due to two critical events: the military operation in Venezuela and a new federal travel ban. The most immediate impact on air travel is the partial easing of flight restrictions following the US military action in Caracas on January 3. The emergency Notice to Airmen (NOTAM), which had prohibited flights over parts of the Eastern Caribbean, expired at midnight ET on January 4. Airlines such as Delta, JetBlue, and American Airlines are quickly working to resume flights to popular destinations like Puerto Rico, Aruba, and the Virgin Islands. However, this recovery is far from seamless, with over 1,000 flight cancellations and 6,000 delays reported across the US as airlines struggle to reposition aircraft and crews.

While regional Caribbean routes are returning to service, U.S. carriers remain banned from flying through Venezuelan airspace. This restriction is causing longer flight times for travelers heading to South American cities like Bogotá and São Paulo, as airlines are forced to reroute their planes around the conflict zone.

Major Route Disruptions: Ongoing Delays and Rerouting

Miami (MIA) to São Paulo (GRU): Due to Venezuelan airspace restrictions, flights from Miami to São Paulo now take a longer route through the Atlantic Arc, heading far east before cutting south to bypass the Venezuelan coastline. This detour results in a significant delay of 60 to 90 minutes, and airlines are still facing challenges in optimizing this new routing strategy.

New York (JFK) to Buenos Aires (EZE): Flights from JFK to Buenos Aires are rerouted through the Andean Corridor, flying west over the Caribbean toward Panama and then hugging the Pacific coast and Andes mountains. This adds 90 to 120 minutes to the flight time, with airlines working to manage the extended path while ensuring passenger comfort and safety.

Atlanta (ATL) to Bogotá (BOG): Flights from Atlanta to Bogotá must stay strictly within Panamanian and Western Colombian airspace, completely avoiding Venezuela’s border. This rerouting causes delays of 30 to 45 minutes, as airlines navigate these airspace restrictions and manage more complex flight plans to ensure safe and timely arrivals.

Houston (IAH) to Rio de Janeiro (GIG): Flights from Houston to Rio de Janeiro have been rerouted through Central America and across the Brazilian Amazon to avoid northern borders affected by the Venezuelan conflict. This “Amazonian Deep Bypass” adds 75 to 100 minutes to flight times, requiring airlines to adjust fuel loads and schedules for the extended journey.

Miami (MIA) to Georgetown (GEO): Flights from Miami to Georgetown now require a significant deviation, taking a massive “U-turn” around the Guiana Shield to avoid eastern Venezuelan airspace. This rerouting adds 50 to 70 minutes to the flight time, creating further logistical challenges for airlines in terms of crew schedules and fuel management.

Dallas (DFW) to Santiago (SCL): Flights from Dallas to Santiago are now rerouted almost entirely over the Pacific Ocean, entering South American airspace only once they reach the latitude of Peru or Chile. This Pacific Coastal Route adds considerable delay, with flights taking significantly longer than usual due to the expanded flight path. Airlines continue to adjust operationally to the added time.

Details on South American Rerouting

As of January 2026, U.S. flights to South America are experiencing significant changes due to airspace restrictions imposed by the Venezuelan conflict. The rerouting of flights to bypass Venezuelan airspace has led to extended travel times, operational challenges, and disruptions across various regions. Below, we break down how these adjustments are impacting flights between the U.S. and South America.

U.S. to Brazil (e.g., MIA to GRU): Flights from the U.S. to Brazil, which previously flew directly over Venezuela and the Amazon, are now being rerouted either east over the Atlantic Ocean or west via Panama and Colombia. This detour adds anywhere from 45 to 90 minutes to travel times. Passengers on these flights are facing longer durations in the air, and airlines are adjusting schedules accordingly. While some flights are resuming with the rerouting, the added time is straining airline operations and affecting flight crews, potentially causing delays in subsequent connections.

U.S. to Argentina (e.g., JFK to EZE): Flights from New York to Buenos Aires typically pass through central Venezuela, but this path is no longer viable due to the airspace restrictions. Instead, these flights are being pushed much further west, often flying over the Pacific coast or deep into Colombia and Ecuador. This dramatic rerouting adds 1 to 2 hours to the total flight time. While passengers are arriving later, the longer routes also introduce logistical challenges, including fuel management and crew timing, which further exacerbate delays. Travelers are advised to be prepared for significant delays and should confirm any potential reroutes with their airline.

U.S. to Colombia (e.g., ATL to BOG): Flights from Atlanta to Bogotá often clipped western Venezuela but are now being rerouted to hug the Panamanian border or stay strictly within Colombian coastal airspace. This change has resulted in delays of 20 to 40 minutes, which is less severe compared to longer-haul routes but still enough to disrupt scheduling. Passengers traveling to Colombia are urged to check for delays and plan extra time between connections to accommodate these added travel times. The rerouting may also affect other connecting flights from Bogotá, especially for those traveling onward to other South American destinations.

Intra-South America: Intra-South American routes, particularly those between Venezuela and neighboring countries like Brazil and Colombia, have been severely disrupted. Direct flights between Caracas and these countries have been largely suspended due to the ongoing conflict and the airspace restrictions imposed by the FAA. This has paralyzed business travel and created a logistical nightmare for anyone needing to travel between these regions. The indefinite suspension of these flights means that passengers must seek alternative routes, potentially causing longer travel times and more complex itineraries.

Specific Operational Challenges

The rerouting of flights has led to several operational hurdles for airlines, further impacting passenger experience. These challenges include GPS jamming, fuel stops, and crew timing restrictions, all of which have contributed to delays and cancellations across the board.

GPS Jamming: Pilots flying near the Venezuelan border have reported significant electronic interference, including GPS jamming, which is causing major disruptions in navigation. As a result, many airlines are opting to use Inertial Navigation Systems (INS) and ground-based radar to guide flights. These alternative systems, while effective, require greater spacing between planes to ensure safety. This added distance between aircraft has led to further delays, as it takes longer to clear airspace and coordinate with air traffic control.

Fuel Stops: Medium-range aircraft, such as the Boeing 737 Max and Airbus A321neo, which typically fly on the edge of their range when traveling to deep South America, are now being forced to make unscheduled technical fuel stops. These stops are particularly common for routes like Miami to Georgetown (GEO) or Atlanta to Bogotá (BOG), where the extended flying time due to the rerouting exceeds the aircraft’s fuel reserves. Common fuel stop locations include Manaus in Brazil and Panama City. These unexpected stops add time to already lengthy journeys and can cause further delays.

Crew Timing: The increased flight times due to rerouting are also causing significant issues with flight crew schedules. Many flight crews are being pushed past their legal “duty hours,” which has led to last-minute cancellations and rescheduling of flights. Airlines must adhere to strict regulations regarding crew working hours, and when the added flight times push crews beyond those limits, it can cause a cascade of operational issues. This has particularly affected flights between the U.S. and South America, leading to frustration for passengers and airlines alike.

Advice for South American Travelers

Travelers heading to South America should take extra precautions and be prepared for the ongoing disruptions caused by rerouted flights and operational challenges.

Check for “Technical Stops”: When booking or checking your flight status, be sure to check if a “Technical Stop” has been added to your itinerary for refueling. This is especially important for flights with medium-range aircraft, as these planes may require unexpected fuel stops due to the extended flight times caused by the detours.

Buffer Connections: For those connecting through major hubs like São Paulo, Bogotá, or Lima, it is strongly recommended to leave at least 3–4 hours between connecting flights. Given the longer flight times and potential delays, this buffer time will help ensure that you don’t miss your onward connection.

App Tracking: To stay updated on your flight’s actual path and current delays, use flight tracking apps like FlightRadar24. These apps will show you the real-time flight path, allowing you to see if your plane is making a wide arc around Venezuela. If you notice such a deviation, expect a delay in arrival, often longer than the initial estimate provided by your airline.

Impact Summary for Passengers

The ongoing rerouting of flights to and from South America is having a significant impact on travelers, with longer flight times, unexpected fuel stops, and potential missed connections.

Refueling Stops: For flights like Miami to Georgetown or Atlanta to Bogotá, smaller aircraft (such as the Boeing 737) may now require a technical fuel stop, adding time to an already extended journey. This can be frustrating for passengers, as these stops often occur in less convenient locations and are outside the airline’s usual planning procedures.

Increased Fares: To cover the increased operational costs, most carriers have begun implementing a “Conflict Surcharge,” ranging from $40 to $120. This surcharge helps offset the significant increase in jet fuel consumption due to the longer detours. Passengers should be aware of this extra charge when booking flights to South America.

Missed Connections: Passengers traveling from South America back to the U.S. are particularly vulnerable to missed connections, as the 1–2 hour delays from rerouted flights often result in missed domestic connections in major hubs like Miami or Houston. Travelers should allow extra time between international and domestic connections to avoid this issue.

Miami joins cities like New York, Atlanta, Dallas, and Houston in facing major flight delays to São Paulo, Bogotá, Rio de Janeiro, and Santiago due to the Venezuelan airspace shutdown, disrupting travel between the US and South America, including Brazil, Argentina, Colombia, and Chile.

Conclusion

Venezuelan airspace shutdown has severely impacted flights from cities like Miami, New York, Atlanta, Dallas, and Houston, causing significant delays on routes to São Paulo, Bogotá, Rio de Janeiro, and Santiago. This disruption is felt across travel between the US and South America, including countries such as Brazil, Argentina, Colombia, and Chile. The rerouting of flights to avoid Venezuelan airspace has led to longer flight durations, unexpected fuel stops, and logistical challenges for airlines, ultimately affecting passengers’ travel plans. With no immediate resolution in sight, these ongoing disruptions are set to continue impacting both travelers and airline operations for the foreseeable future.
