Airlines Cancel LAX & SFO Flights to Mexico Amid Civil Unrest

Major U.S. and Canadian airlines canceled flights to popular tourist destinations in Mexico from key California hubs, including Los Angeles International Airport (LAX) and San Francisco International Airport (SFO), on February 23-24, 2026. The disruption, which affected more than 175 flights nationwide in Mexico, was a direct response to widespread civil unrest and violence following the death of a prominent cartel leader. The events prompted the U.S. Department of State to issue a "shelter in place" advisory for American citizens in affected regions.

The widespread flight cancellations represent a significant case of Irregular Operations (IROPS), an industry term for disruptions caused by unforeseen events. The security situation deteriorated rapidly, forcing carriers to prioritize passenger and crew safety over maintaining scheduled services. Airlines including American, United, Delta, Southwest, Alaska, Air Canada, and WestJet suspended operations to airports in the state of Jalisco, most notably Licenciado Gustavo Díaz Ordaz International Airport (PVR) in Puerto Vallarta and Miguel Hidalgo y Costilla Guadalajara International Airport (GDL).

Cause of the Disruption

According to a security alert issued by the U.S. Mission in Mexico on February 22, 2026, the civil unrest was triggered by the death of Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” the leader of the Jalisco New Generation Cartel (CJNG). His death led to immediate and coordinated acts of violence, including the establishment of roadblocks by criminal groups. These blockades severely impacted ground transportation and access to airports for both passengers and airline crews, creating an untenable operational environment.

The security alert confirmed that U.S. government employees in the affected states were instructed to shelter in place until further notice. This official guidance underscored the severity of the situation and was a key factor in the airlines' decisions to halt flights. The disruptions highlight the vulnerability of airline networks to geopolitical instability and localized security crises, which can escalate with little warning.

Official Guidance and Advisories

The response from government bodies was swift. The U.S. Department of State, through its Bureau of Consular Affairs, acted on its "duty of care" obligation by issuing the Security Alert for ongoing operations. The advisory urged U.S. citizens to avoid public spaces, maintain a low profile, and monitor local media for updates. This guidance was issued under the existing Mexico Travel Advisory, which already recommended U.S. citizens "Exercise Increased Caution" when traveling to the country, with higher-level warnings for specific states like Jalisco.

In a related statement, Texas Governor Greg Abbott urged residents in Mexico to adhere to the official guidance. "Texans' safety is my top priority, whether they are here at home or traveling abroad," he stated. "Situations on the ground can change quickly, and staying informed can save lives." This reflects the coordinated messaging from U.S. officials to citizens impacted by the security crisis.

Operational Impact and Airline Response

For the aviation industry, events like these are a critical test of crisis management protocols. The decision to cancel flights is a complex one, balancing commercial interests with the non-negotiable priority of safety. In line with industry best practices for IROPS, affected airlines activated contingency plans. These included proactively canceling flights to avoid stranding aircraft, crew, and passengers in a volatile security environment.

Carriers also issued travel waivers, allowing passengers with bookings to or from the affected airports to change their flights without a fee. This measure helps mitigate customer frustration and provides flexibility for those whose travel plans were directly impacted by the unrest. The financial cost of such disruptions includes lost revenue from canceled flights, expenses for passenger re-accommodation, and costs associated with repositioning aircraft and crew once operations can safely resume. The incident serves as a stark reminder of how non-technical, external factors can profoundly impact airline operations.

Why This Matters

This series of flight cancellations underscores the significant operational and financial risks that geopolitical instability poses to the airline industry. It demonstrates how quickly a regional security event can disrupt major international travel corridors, forcing airlines to absorb costs and manage complex logistical challenges. For passengers and aviation professionals, it highlights the importance of monitoring official travel advisories and recognizing that airline schedules are subject to rapid change based on security conditions on the ground.
