Sources: 7. Developments: 2. Several Mexican airports, including major hubs like Mexico City International Airport (AICM), have sought to increase flight slots to accommodate rising industry demand. At AICM, officials noted that further capacity increases depend on infrastructure studies, safety procedures, and the successful management of currently authorized slots. In response to these capacity needs, Mexico’s Secretariat of Infrastructure, Communications and Transportation (SICT), via the Federal Civil Aviation Agency (AFAC), issued new guidelines for assigning takeoff and landing slots at aerodromes with Level 2 saturation potential. Effective September 5, 2026, these regulations require air carriers and airport administrators to coordinate schedule adjustments to mitigate congestion. The new rules mandate that slot assignments be conducted in an “impartial, transparent, and non-discriminatory manner” for all relevant concessionaires and service providers. ## Timeline ### 2026-09-04: Mexico issues new aviation slot allocation guidelines Mexico's AFAC has issued new mandatory guidelines for takeoff and landing slot allocations at Level 2 saturation aerodromes to prevent congestion and ensure efficient airport infrastructure use. 5 sources. https://clstr.news/cluster/mexico-issues-new-aviation-slot-allocation-guidelines ### 2026-08-31: Mexican airports seek increased flight slots to meet demand Several Mexican airports, including Mexico City International Airport, are seeking increased flight slots to manage growing demand, pending infrastructure and safety capacity assessments. 2 sources. https://clstr.news/cluster/mexican-airports-seek-increased-flight-slots-to-meet-demand --- Cite as: Mexican aviation capacity and slot regulation.
