The 2026 FIFA World Cup will create one of the most complex air transportation operations in aviation history. With 48 national teams, 104 matches across 16 host cities in Mexico, the United States, and Canada, airlines are managing unprecedented logistical challenges involving charter flights, fleet planning, crew fatigue management, airport slot coordination, and security requirements. More than 65% of participating federations are reportedly using dedicated charter operations instead of regular commercial services to ensure operational control, confidentiality, and national branding opportunities.

Many teams are relying on widebody aircraft for long haul travel, including Airbus A350 operations by several national carriers. Beyond transporting players, airlines must coordinate reinforced flight crews, weight and balance considerations, private terminal access, and extensive safety management systems. The scale of the tournament means aviation operations will play a critical role in the overall success of the event, especially as teams and supporters move between cities spread across three countries.

The United States has proposed new tariffs of 10% to 12.5% on imports from more than 60 countries, including Mexico, citing concerns that those countries have not done enough to prevent products made with forced labor from entering their supply chains. The proposal is part of a broader trade initiative by the Trump administration and is still subject to a public consultation and review process before taking effect.

Mexico’s Economy Ministry responded by stating that exports complying with the rules of the USMCA (T MEC) would be exempt from the proposed 10% tariff. According to Mexican authorities, more than 85% of Mexico’s exports to the United States currently meet those requirements, meaning the majority of trade would remain unaffected. Mexico plans to hold discussions with the U.S. Trade Representative over the next 45 days to demonstrate its efforts against forced labor and seek modifications to the proposal.

Mexico will make steel and aluminum tariffs its top concern in the formal USMCA review talks with the United States. Economy Secretary Marcelo Ebrard said the 50% tariff imposed on steel and aluminum exports is “unsustainable” and lacks justification. Mexico plans to argue that North America must strengthen its competitiveness against other global regions and will push for tariff relief during upcoming negotiation rounds in Washington and Mexico City.

The issue comes as broader USMCA discussions begin, with the United States seeking stricter regional content requirements for manufactured products while Mexico focuses on protecting key industries affected by trade barriers. Steel, aluminum, automotive manufacturing, and agricultural trade are expected to dominate the negotiation agenda in the coming months.

The appreciation of the Mexican peso is helping airlines mitigate part of the financial impact caused by the escalating conflict in the Middle East, according to analysts from Monex. Rising geopolitical tensions have pushed fuel prices upward globally, increasing operational costs across the aviation industry.

Despite pressure from higher jet fuel prices, the stronger peso has reduced part of the exchange rate related burden for airlines operating in Mexico. Analysts warn, however, that continued instability in energy markets could still affect profitability in the coming months.

The Federal Civil Aviation Agency (AFAC) reiterated that the deadline to implement the new aircraft registration and deregistration certificates in Mexico remains set for November 26, 2026. The measure forms part of Circular Obligatoria 45.01/24, which updates the technical standards for nationality markings, registration plates, and identification systems on Mexican civil aircraft.

Authorities explained that all aircraft must carry a visible identification plate inside the cabin near the main entrance, while drones, balloons, and other aircraft categories will follow specific placement requirements. The plates must include engraved information such as registration marks, serial number, manufacturer, year of manufacture, owner, and operator details. AFAC, Mexico’s aviation regulatory authority, confirmed that inspections will continue throughout the transition period to ensure compliance with the new standards.

A Mexican air traffic controllers’ union warned it could move toward a strike due to ongoing technical failures, staff shortages, and salary reductions that they say have affected operations for years. The Sindicato Nacional de Controladores de Tránsito Aéreo (Sinacta) stated that controllers have repeatedly alerted authorities about deteriorating systems and increasing operational risks, especially as Mexico prepares for higher international air traffic ahead of the 2026 World Cup.

Union representatives also claim salaries have fallen significantly compared to previous years, while staffing levels remain insufficient to handle current and future demand. The organization plans to present a formal labor complaint before federal authorities, raising concerns about possible disruptions to flight operations across the country if the conflict escalates.

Mexico’s aluminum industry expects the country to receive preferential treatment during the 2026 review of the United States Mexico Canada Agreement (T MEC), despite current U.S. tariffs on steel and aluminum. Eugenio Clariond Rangel, president of the Mexican Aluminum Institute (Imedal), stated that Mexico remains in a strong strategic position because of its integration with North American supply chains.

The sector opposes proposals that would require only primary aluminum produced within North America to qualify under T MEC rules of origin. Instead, the industry proposes allowing aluminum from “market economies” to qualify, arguing that stricter rules could reduce competitiveness for regional manufacturing.
