Slots, Tariffs, and Takeoffs: The Aviation Risks Behind Mexico’s World Cup Opportunity

On the night of February 10, 2026, the FAA abruptly closed all airspace over El Paso, grounding commercial, cargo, and private flights with no prior coordination with local authorities or airport operators. The agency cited unspecified “security reasons” and warned that aircraft violating the restriction could be intercepted. The order was lifted hours later, without explanation.

The cause remains disputed. US Transportation Secretary Sean Duffy said Mexican cartel drones had breached US airspace and were neutralized by the United States Department of Defense. Other officials suggested the shutdown followed a coordination failure during testing of a counter-drone laser near Fort Bliss, reportedly fired at what was later identified as a Mylar balloon.

Regardless of the trigger, the precedent was striking. For the first time since the September 11 attacks, a major US airport was effectively shut down without prior coordination with authorities and stakeholders.

The incident exposed the fragility of the aviation corridor linking the United States with northern Mexico. El Paso serves roughly four million passengers annually and is a key gateway to Ciudad Juárez and the broader border economy.

The timing is significant. The disruption occurred just four months before the 2026 FIFA World Cup, which is expected to bring roughly 5.5 million visitors to Mexico. For companies planning corporate hospitality, executive travel, or cross-border logistics, the lesson is fundamental: disruptions in the US–Mexico aviation system can materialize suddenly, and during peak demand, the consequences could be far greater.

Cleared for Takeoff—If Washington Approves

Over the past 18 months, the US Department of Transportation has used regulatory tools to reshape the US–Mexico aviation corridor—blocking routes, pressuring slot allocations, and challenging the partnership that anchors a large share of cross-border premium travel.

In September 2025, regulators ordered the termination of the joint venture between Delta Air Lines and Aeroméxico. Established in 2017 under antitrust immunity, the partnership allowed the airlines to coordinate schedules, pricing, and revenue-sharing across more than 30 cross-border routes. Together, the carriers account for roughly 20% of US–Mexico aviation capacity on what is now the world’s second-busiest international air corridor.

US regulators argued the arrangement produced anticompetitive effects. Both airlines appealed, and in November 2025 the United States Court of Appeals for the Eleventh Circuit issued a stay allowing the partnership to continue operating while litigation proceeds. The case could extend into late 2026.

The decision was not isolated. Since mid-2025, Washington has accused Mexico of violating the 2015 US–Mexico Air Transport Agreement by banning cargo operations at Mexico City International Airport, forcing cargo carriers to relocate to Felipe Ángeles International Airport, and reallocating airport slots in ways perceived as favoring Mexican airlines.

In October, US authorities revoked 13 routes operated by Aeroméxico, Volaris, and Viva Aerobus. Mexico responded cautiously. In November, authorities reassigned six AICM slots to US carriers, widely interpreted as a signal that Mexico’s bargaining leverage in the dispute was limited.

Consolidation and Concentrated Risk

At the same time, Mexico’s domestic aviation market is consolidating.

In December 2025, Volaris and Viva Aerobus announced plans to merge, creating what would become Latin America’s largest low-cost airline group. The combined carrier would operate roughly 250 Airbus A320-family aircraft, transport 60 million passengers annually, and control nearly 70% of Mexico’s low-cost domestic market.

The transaction is under review by Mexico’s Comisión Nacional Antimonopolio, the newly created competition authority that replaced the Federal Economic Competition Commission following the country’s 2024 constitutional reforms.

Meanwhile, Aeroméxico remains the dominant legacy carrier, accounting for roughly 47% of domestic traffic and expanding internationally with new routes to Barcelona and Paris.

The likely outcome is a de facto duopoly: one legacy carrier and one mega low-cost group. For companies, that structure could mean less negotiating leverage, higher concentration risk, and greater exposure to operational disruptions affecting a single airline.

The World Cup as Stress Test

The 2026 FIFA World Cup will bring 13 matches to Mexico: five in Mexico City, four in Guadalajara, and four in Monterrey. The tournament is expected to attract 5.5 million visitors, generating up to USD 3 billion in economic activity.

Mexico has committed roughly USD 7 billion to airport upgrades nationwide. Yet the main bottlenecks remain concentrated in a handful of hubs.

At Mexico City International Airport, an MXN 8 billion modernization program is underway. Monterrey International Airport is expanding capacity from 11 to 16.5 million passengers, while Guadalajara International Airport is rapidly adding gates in existing terminals and supporting infrastructure.

​​On March 13, the director general of Mexico City International Airport, Admiral Juan José Padilla, publicly acknowledged that renovation works will not be fully completed before the start of the 2026 World Cup. Speaking in a radio interview, Padilla confirmed that between 10 and 20 percent of works will remain unfinished when the tournament begins, including sections of Terminal 1's ambulatory, baggage carousels, elevators, drainage systems, and parking.

In effect, the World Cup compresses several aviation risks into a single window:

• Regulatory: The Delta–Aeroméxico dispute and broader aviation tensions remain unresolved.
  
  
• Competitive: The Volaris–Viva merger review overlaps with peak travel demand.
  
  
• Security: The El Paso incident showed that cross-border airspace disruptions can occur without warning.
  
  
• Infrastructure: Construction timelines leave little buffer for delays.

Business aviation will feel the pressure first. Severe congestion is expected across host cities, with tight constraints on slots, parking, handling capacity, and fuel availability.

For operators flying into Mexico City, Toluca remains the primary alternate airport, with Querétaro and Puebla offering secondary options.

The USMCA Dimension

Although aviation services are excluded from the United States–Mexico–Canada Agreement, the current aviation dispute is unfolding just months before the treaty’s July 2026 review.

Mexico is now the world’s sixth-largest aerospace producer, and roughly 80% of its aerospace exports go to the United States. Rising tariffs on metals, semiconductors, and aerospace components have already squeezed margins.

Companies including Airbus, Boeing, Bombardier, Safran, and GE Aerospace have warned about the impact. According to FEMIA, Mexico’s aerospace federation, sector growth slowed to about 9% in early 2025, down from a historical range of 13–16%.

For Mexico, resolving the aviation dispute before the USMCA review begins is strategically important. Entering negotiations with unresolved conflicts over routes and airport slots could weaken its position on far more consequential issues such as manufacturing rules and regional content requirements.

Washington has increasingly used sectoral disputes—from aviation to energy and migration—as leverage in broader trade negotiations. There is little indication that approach will change.

How Speyside Can Help

Speyside Group advises multinational companies on political risk, regulatory navigation, and stakeholder engagement across Latin America.

For companies exposed to Mexico’s aviation environment—through corporate travel, logistics, hospitality, or aerospace manufacturing—we support clients in three key areas:

Regulatory intelligence and scenario planning
Tracking developments in the Delta–Aeroméxico litigation, the Volaris–Viva merger review, and the US–Mexico aviation dispute to anticipate regulatory shifts.

Government relations and stakeholder mapping
Engaging effectively with regulators including Agencia Federal de Aviación Civil, Secretariat of Infrastructure, Communications and Transportation, and airport operators such as Grupo Aeroportuario del Pacífico, Grupo Aeroportuario del Sureste, and Grupo Aeroportuario del Centro Norte.

Crisis preparedness and contingency design
Developing contingency plans for aviation disruptions that could affect executive travel, corporate hospitality, and supply chain operations during the World Cup period.

The Bottom Line: Mexico's aviation system is not broken. Flights operate, airports function, and the infrastructure investments ahead of the World Cup are real. But the system now operates in a geopolitical environment where US regulatory power, domestic consolidation, and security tensions have narrowed the margin for error. Companies that treat connectivity as a given, rather than a variable subject to political risk, may find themselves exposed at a critical moment. The World Cup is five months away. The time to stress test and prepare is now.

FAQ: US–Mexico Aviation & 2026 World Cup Risks

Q: How will the 2026 World Cup impact Mexico's aviation infrastructure?
A: The tournament is projected to add 5.5 million visitors in June and July. This influx will place immense strain on major hubs such as Mexico City (AICM), Monterrey, and Guadalajara, which are currently racing to complete major infrastructure upgrades before the tournament begins.

Q: What is the current regulatory status of the Delta–Aeroméxico joint venture?
A: In September 2025, the US Department of Transportation ordered the termination of the joint venture, citing anticompetitive effects. However, the Eleventh Circuit Court of Appeals placed the order on hold in November 2025, allowing the partnership to continue operating while the legal appeals process unfolds into late 2026.

Q: How is the domestic aviation market consolidating within Mexico?
A: Volaris and Viva Aerobus announced a merger in December 2025, which is currently pending review by Mexico's competition authority, the CNA. If approved, this would create Latin America's largest budget airline group, potentially shifting the Mexican market toward a de facto duopoly alongside legacy carrier Aeroméxico.

Q: Why does the aviation dispute matter for the upcoming USMCA review?
A: Resolving the aviation dispute is critical because entering the July 2026 USMCA review with unresolved bilateral frictions weakens Mexico's negotiating leverage. This is particularly dangerous for Mexico's aerospace manufacturing sector, which is the sixth-largest globally and exports approximately 80% of its products to the United States.

Q: How can Speyside help your company navigate these aviation and regulatory challenges?
A: Speyside provides targeted support through regulatory intelligence, helping clients anticipate disruptions stemming from bilateral disputes and antitrust reviews. We also assist with stakeholder mapping to navigate key regulators (such as AFAC and SICT) and airport operators, alongside designing crisis preparedness plans to ensure corporate travel and supply chains remain resilient during the World Cup.
