The United States government has issued a stern warning to Mexican aviation authorities, threatening to restrict Mexican airline operations into the U.S. due to what it perceives as unfair competition and violation of bilateral agreements. The dispute centers on Mexico’s handling of airport slot allocations at Mexico City International Airport and its decision to force U.S. cargo carriers to relocate operations to a separate airport facility. These moves, American officials argue, disadvantage U.S.-based airlines and hinder the competitive balance established under longstanding aviation treaties.
The U.S. Department of Transportation is considering rescinding approvals for new routes by Mexican carriers and may revoke the antitrust immunity that currently allows joint operations between Delta Air Lines and Aeromexico. This immunity has enabled the two carriers to coordinate schedules and share revenue on transborder flights, benefiting from economies of scale. Without it, the partnership would lose key strategic advantages, potentially reducing available flight options and increasing fares for consumers.
The root of the dispute lies in decisions by Mexican authorities to restructure air traffic at Mexico City’s main airport, citing congestion and safety concerns. These changes have particularly impacted cargo operators, many of which are American, forcing them to move to the newer Felipe Ángeles International Airport, located further from the city’s commercial centers. U.S. officials argue that the relocations are discriminatory and lack transparency, violating the spirit of the 2015 U.S.–Mexico air transport agreement.
In response to the growing tensions, the U.S. has demanded that Mexican airlines submit detailed flight schedules for approval and comply with new oversight measures. The move signals a readiness to escalate the situation unless Mexico takes corrective action. Industry analysts warn that deteriorating aviation relations could disrupt travel and trade between the two countries, particularly ahead of major events like the 2026 World Cup, which will involve substantial cross-border air travel.
The standoff reflects broader economic friction between the neighboring countries amid growing concerns over regulatory consistency and trade fairness. While both sides have expressed a desire to maintain strong ties, the current trajectory suggests a deepening rift unless swift diplomatic resolution is achieved. A balanced aviation environment that promotes mutual growth and fair competition will be key to avoiding long-term damage to cross-border connectivity.
