SFO flights to Mexico resume after cartel-linked unrest; what travelers should know about safety
Flights resume after brief disruption
Commercial air service from San Francisco International Airport (SFO) to several destinations in Mexico began returning to normal early this week after a short period of cancellations and delays tied to security unrest in western Mexico. The disruption followed a major Mexican security operation on February 22, 2026, and a wave of retaliatory violence that included road blockades and vehicle fires in multiple states, with particularly visible impacts in and around Puerto Vallarta and Guadalajara.
SFO is among several U.S. gateways with nonstop service to Mexico. From the Bay Area, nonstop options typically include tourist and business routes to destinations such as Puerto Vallarta, Guadalajara, Mexico City, Cancún, San José del Cabo and Monterrey, depending on carrier schedules and seasonality. During the disruption window, airlines temporarily paused or reduced service on some west-coast-to-Mexico routes, then began restoring flights as conditions stabilized and airports resumed standard operations.
What triggered the cancellations
Mexican authorities confirmed that the operation resulted in the death of Nemesio Oseguera Cervantes, also known as “El Mencho,” the longtime leader of the Jalisco New Generation Cartel. After his death, Mexican officials reported retaliatory actions across parts of the country, including blockades and arson incidents that interfered with ground transportation and contributed to temporary flight disruptions at key tourist and regional hubs.
Authorities and airlines treated the episode as a fast-moving security event, with travel conditions varying significantly by state and even by city.
Safety guidance: uneven risk by region
U.S. diplomatic officials issued shelter-in-place guidance for certain locations during the height of the unrest, including parts of Jalisco and nearby areas that share infrastructure and transportation corridors with major resorts. The advisory posture underscored a central reality for travelers: security conditions in Mexico are not uniform, and risks can differ sharply across states.
Separately from these short-notice alerts, ongoing U.S. travel advisories for Mexico continue to list certain states at the highest caution level (“Do not travel”), while other areas frequently visited by Americans may carry lower advisory levels but still warrant heightened situational awareness.
What travelers from SFO can do now
Check airline waivers and rebooking rules for Mexico routes, especially if your ticket was issued before the disruption period and you prefer to postpone.
Review current state-level travel advisories for your specific destination and any planned overland side trips; guidance can change quickly after major security events.
Avoid travel that depends on long, late-night drives between cities, and plan airport-to-hotel transfers with reputable providers when conditions are unsettled.
Monitor local authorities’ operational updates in your destination area, including road closures and security activity that may not affect airports but can affect ground movement.
Bottom line
SFO-to-Mexico flights are resuming, but the decision to travel safely now depends on the precise destination, the ability to limit overland movement, and the latest government and airline guidance. For travelers heading to areas that were directly affected by the February 22–23 unrest, flexibility and close monitoring remain essential.
