Mexico Airport Security Disruptions — Culiacán · Morelia · Zihuatanejo
Live status & terminal operations monitoring
Regional Mexican airports — Culiacán (MMCL), Morelia (MMMM), Zihuatanejo (MMZH) — have experienced episodic ground security situations affecting terminal operations during 2025–2026. FAA Class B advisories have been issued at intervals; AFAC NOTAMs have flagged short-duration ground events across the Mazatlán (MMFR), Monterrey (MMTC), and Mérida (MMID) flight information regions. Main Mexican airspace continues routine operation, and major hubs Mexico City (MMMX) and Cancún (MMUN) have been unaffected.
Executive summary
Selected regional Mexican airports — Culiacán (MMCL / CUL) in the Mazatlán FIR (MMFR), Morelia (MMMM / MLM) in the Mexico City FIR (MMEX), and Zihuatanejo (MMZH / ZIH) on the Pacific coast — have experienced episodic ground security situations impacting terminal operations through 2025–2026. Events are typically short-duration and affect passenger movement, fuelling, and surface operations rather than en-route airspace. The FAA has issued Class B advisories at intervals; AFAC has issued NOTAMs covering ground-side impact. The Monterrey FIR (MMTC) and Mérida FIR (MMID) have seen sporadic terminal-level notices at smaller fields. Mexico City Benito Juárez (MMMX), Cancún (MMUN), Guadalajara (MMGL), and Mérida (MMMD) have continued routine operations throughout. Next review tracks AFAC NOTAM cadence and any FAA advisory amendment.

Regulatory context
FAA Class B advisories have been issued at intervals for U.S.-registered operators concerning terminal-level conditions at the named regional airports; the advisories do not restrict overflight and do not affect en-route Mexican airspace. AFAC (Agencia Federal de Aviación Civil) publishes NOTAMs covering ground operations and short-duration disruptions through standard ICAO channels. SCT (Secretaría de Comunicaciones y Transportes) issues policy-level notices. ICAO NAM region safety publications cover broader North American coordination. Operators should reference airport concessionaire notices from ASA, GAP, ASUR, and OMA for terminal-specific status. Live NOTAM verification through official AFAC channels is required prior to dispatch.
Industry implications
Operational impact is concentrated at the terminal level rather than en-route. Mexican airspace remains fully accessible, and major international gateways (MMMX Mexico City, MMUN Cancún, MMGL Guadalajara, MMMD Mérida) have continued routine operations throughout the advisory periods. Carriers serving the affected regional fields have at times implemented schedule adjustments, station-staffing changes, and short-duration ground holds tied to specific events; some carriers have temporarily reduced or repositioned service. Insurers monitor ground-handling and crew-positioning exposure at the named regional airports rather than en-route hull risk. Lessors and operators report no material impact on overflight planning across the MMFR, MMTC, MMID, and MMEX flight information regions. The pattern is regional and episodic; structural Mexican airspace remains operational.

Mexico Airport Disruptions — Frequently Asked Questions
Common search queries answered with current status, FIR codes, and source citations.
- Which Mexican airports have experienced operational disruptions in 2026?
- Episodic ground security situations have impacted terminal operations at Culiacán (CUL, MMCL), Morelia (MLM, MMMM), and Zihuatanejo (ZIH, MMZH). Disruptions are typically short-duration ground events affecting passenger movement, fuelling, and surface operations. Mexican airspace (MMFR Mazatlán FIR, MMTC Monterrey FIR, MMID Mérida FIR, MMEX Mexico City FIR) remains operational throughout. Status is tracked against AFAC NOTAMs and SCT advisories.
- Are Mexico City (MEX) and Cancún (CUN) hubs affected by these disruptions?
- No. Benito Juárez International (MEX, MMMX), Cancún (CUN, MMUN), Guadalajara (GDL, MMGL), and Mérida (MID, MMMD) have continued routine operations through these regional events. The disruption pattern is regional and ground-side, affecting specific terminal facilities rather than en-route airspace or major international gateways.
- What sources track Mexican airport advisories and FAA notices?
- Public sources include AFAC (Agencia Federal de Aviación Civil) NOTAMs, SCT (Secretaría de Comunicaciones y Transportes) bulletins, FAA Class B advisories for U.S.-bound operators, and ICAO NAM regional safety publications. Operators should also reference airport-specific notices from ASA (Aeropuertos y Servicios Auxiliares) and concessionaire operators such as GAP, ASUR, and OMA.

Indices are raw computational output and do not represent opinions, assessments, recommendations, or advice of any kind. They do not replace official NOTAMs, SIGMETs, AIPs, or communications from aviation authorities. Operators must independently verify current airspace status through official channels.
