The United States blocked 13 flight routes operated by Mexican airlines after finding that Mexico’s aviation decisions conflicted with the bilateral air transport agreement. The U.S. Department of Transportation issued the order on October 28, 2025, and stated that Mexico restricted access for U.S. carriers at Mexico City International Airport while Mexican carriers continued expanding into U.S. airspace.
The decision focuses on Felipe Angeles International Airport, a newer airport north of Mexico City. The suspension freezes new flight applications from Mexican airlines into the United States until Mexico restores equal treatment for U.S. carriers. This situation represents one of the most serious aviation tensions between the two countries in many years.
Routes and Airlines Affected
The U.S. order targeted 13 routes operated or proposed by Aeroméxico, Volaris, and Viva Aerobus. Two of Aeroméxico’s flights from Felipe Ángeles International Airport to Houston and McAllen were active and must be discontinued. One Aeroméxico service from Mexico City International Airport to San Juan, Puerto Rico, was also blocked before launch. Volaris could not proceed with its planned Mexico City to Newark service.
The majority of affected flights belonged to Viva Aerobus, which had scheduled nine launches from Felipe Ángeles to Austin, New York JFK, Chicago O’Hare, Dallas Fort Worth, Denver, Houston, Los Angeles, Miami, and Orlando. These routes never entered service due to the suspension. The cancellations stop growth from Mexico’s newest capital-area airport and freeze further filings for new U.S. flights until compliance is restored.
How the Conflict Started
In 2022, Mexico declared Mexico City International Airport saturated and shifted all cargo flights to Felipe Angeles. U.S. carriers said they lost meaningful access at Mexico City and did not receive comparable slot availability. They also said that Mexico’s slot distributions at MEX favored domestic carriers and limited equal competition.
Industry groups in the United States urged regulators to enforce treaty rules after seeing continued growth approvals for Mexican airlines and restricted U.S. approvals at Mexico City.
U.S. Government Position
The Department of Transportation stated that Mexico limited opportunities for U.S. airlines while allowing its carriers to expand into U.S. airports. According to the ruling, the imbalance violated the fair access requirements in the air transport treaty. The decision pauses new approvals and includes a plan to restrict freight transported in the holds of passenger aircraft operating between Mexico City and the United States.
The freight component is significant because it affects time-sensitive supply chains in key sectors such as automotive components and electronics.
Role of Felipe Angeles Airport
Felipe Angeles Airport was positioned by Mexican authorities as a long-term solution to congestion at Mexico City International Airport. Airlines were encouraged to move traffic there, and Mexican carriers began planning for growth around the airport. Aeroméxico and Viva Aerobus emphasized new services from this facility.
U.S. officials saw these decisions as part of an uneven allocation process. They argued that Mexico shifted flights away from MEX without fair replacement access for U.S. carriers, which placed Felipe Angeles at the center of this case.
Impact on Mexican Airlines
Aeroméxico must remove two operating routes. Volaris loses one planned launch. Viva Aerobus faces the most disruption because its expansion strategy heavily involved Felipe Angeles. These blocked routes force adjustments in fleet assignment and international planning. Aircraft scheduled for U.S. routes may shift to domestic or Latin American markets.
The cancellation delays long-term strategies that were tied to new airport infrastructure and international connectivity growth.
Passenger and Cargo Effects
Passengers who booked affected routes will rebook through Mexico City International Airport or other hubs such as Monterrey. Travelers who relied on direct flights to secondary U.S. airports now face connections and longer travel times. The overall network still exists, but the convenience changes for certain routes.
Cargo operators are preparing backup options. Freight carried in aircraft holds plays a critical role in trade between the two countries. A shift to cargo-only aircraft or alternate airports could increase costs and delays for manufacturers and exporters.
Diplomatic and Industry Response
Mexico objected to the ruling and requested direct discussions with the United States. President Claudia Sheinbaum described the decision as unilateral and called for cooperation. Mexican airlines acknowledged the impact and began reviewing how to adjust operations.
Industry analysts expect negotiations. Resolution could depend on proof of equal slot access and transparent airport-management practices at Mexico City’s aviation facilities.
Market Outlook
Cross-border flying between the United States and Mexico remains one of the busiest international travel segments in the world. With restrictions in place, U.S. airlines maintain growth opportunities while Mexican carriers remain paused. Prolonged delays could affect aircraft deployment, route planning, and commercial timing.
Restoring balanced access is essential for long-term capacity expansion and stability. The outcome depends on policy adjustments, documentation, and verification tied to airport access for both sides.
