Thunderstorm at Mexico City Airport Disrupts 48 Flights, Stranding Over 7,700 Passengers
Why It MattersWeather-driven diversions at a major hub ripple quickly across airline networks, since a handful of storm hours can reroute dozens of flights and thousands of passengers before runways reopen.
What happened
A severe thunderstorm struck the area around Mexico City International Airport (AICM) on Friday afternoon, temporarily suspending flights and disrupting a total of 48 operations. Airport authorities reported that 43 arriving flights were diverted to alternate airports and five departing flights were cancelled, affecting 7,707 passengers.
Runway 05L/23R reopened at 20:01 and resumed operations at 20:04, while Runway 05R/23L became operational at 20:38, restoring normal traffic on both runways. Airport officials credited the prompt response of personnel and deployment of specialized equipment for maintaining safe conditions throughout the disruption.
Among the affected flights were Aeromexico flight 555, scheduled to depart Cancun for Mexico City, and Viva Aerobus flight 1373 on the same Cancun–Mexico City route, which was forced to return to Cancun. Two international flights were also diverted to Cancun: American Airlines flight 257, operating from Miami to Mexico City, and British Airways flight 243, operating from London to Mexico City.
Industry impact & what to watch
Sudden storm cells over a single high-traffic airport can cascade into dozens of diversions and cancellations within hours, since arriving flights need an alternate airport with capacity to absorb them and departing flights simply wait out the closure. Cancun served as the fallback for both domestic legs, such as Aeromexico 555 and Viva Aerobus 1373 on the Cancun–Mexico City route, and long-haul arrivals, including American Airlines 257 from Miami and British Airways 243 from London, showing how one runway closure at a major hub redirects traffic across an airline's entire network rather than staying confined to nearby routes.
Runway reopening times matter more than the storm's duration itself, since the roughly 37-minute gap between 05L/23R and 05R/23L returning to service determined how quickly the backlog of diverted and delayed aircraft could clear. What follows is whether affected carriers can reposition aircraft and crews from Cancun and other diversion points back into the Mexico City schedule without further knock-on delays in the following days.
