A technical malfunction at the Eurocontrol air traffic management center in Brussels on 27 July 2026 led to the complete crash of the slot allocation system, causing widespread disruptions to flights across European airspace. As a result, Eurocontrol activated an emergency European plan that dramatically reduced the number of approved takeoffs from all European airports.
Flight Delays and Passenger Advisories
The Israel Airports Authority reported extended delays affecting both incoming and outgoing flights at European airports throughout the day. Passengers were warned of significant delays continuing over the coming hours and advised to check updated schedules directly with their airlines before arriving at airports. Air
traffic controllers remained engaged in efforts to restore normal operations despite the backlog caused by the collapse of the slot allocation system.
Background on Eurocontrol and Added Regional Pressures
Eurocontrol, an intergovernmental organization headquartered in Brussels, coordinates civil and military air traffic control across Europe, including managing route planning, flight regulation, and slot allocations. The disruption on 27 July followed a separate technical issue with radar systems in Greece reported the previous day, which had increased pressure on regional flight corridors. The combination of these failures intensified congestion and delays on European routes.
Official Statements on Disruption
Airline representatives confirmed the slot allocation system crashed and that the emergency plan impacted
takeoffs throughout European airports. They stated, “The slot allocation system at crashed, and an European emergency plan was activated that will dramatically affect the number of approved takeoffs from all European airports.” Aviation officials noted Eurocontrol’s dual role in coordinating civil and military air traffic synchronization compounds ripple effects from disruptions. Local airport authorities stressed the technical failure fell outside their operational control.
