Ash over Etna, four days of halted airport operations in Catania: around 700 flights cancelled

The management company SAC announced the suspension of all flights arriving at and departing from Catania airport until 3pm on Saturday, August 15, 2026, due to the eruptive activity of Etna (Il Post; Internazionale). This is not a sudden shutdown: operations at the airport have been heavily restricted since August 7, when ash emissions into the atmosphere began interfering with the airspace around the volcano.

The provisional count covers four days. Between August 8 and 11, around 700 flights were cancelled, counting cancellations, missed arrivals and missed departures, and more than 100,000 passengers had to change their plans. This is the most recent verifiable figure at the time of publication and covers only that window: the suspension was subsequently extended, so the overall total for the episode will be higher, but it is not yet available in consolidated form.

The technical reason for the halt is not the lava, it is the dust. Volcanic ash particles suspended at altitude interfere with the operation of jet engines and onboard instrumentation, which is why air traffic is regulated on the basis of dispersion forecasts. The Toulouse Volcanic Ash Advisory Center reported the cloud moving south and southwest, towards Malta and northern Libya. This is the point that makes the episode less local than it might seem: the trajectory of an ash cloud does not stop at national borders, and the area affected is one of the busiest corridors in the central Mediterranean.

The rescheduling of traffic gives a sense of how difficult it is to absorb a stoppage of this scale. More than 250 flights were rerouted to other Sicilian airports: over one hundred to Comiso, around fifty to Palermo, 22 to Trapani. Comparing the two figures — just over 250 rerouted against around 700 cancelled between the 8th and the 11th — shows that the alternative network absorbed only a minority share of the lost traffic. What happened to the remaining connections, and with what solutions for passengers, is not detailed in the cited sources.

Catania’s weight explains the ripple effect. The airport is the fifth largest in Italy by traffic, with more than 12.3 million passengers a year, and the suspension fell during Ferragosto week, the period of peak demand on routes to and from Sicily. A stoppage of similar duration in a low-season month would have produced significantly different figures for the same eruption.

At the institutional level, the discussion has shifted from the volcano to the infrastructure. The Minister for Civil Protection and Sea Policies, Nello Musumeci, summed up his position as follows: “It’s the airport that’s out of place, not the volcano” (Sky TG24). This is a political assessment, not a technical fact, and it opens up a question concerning long-term planning: how much reserve capacity does a regional airport system need when it coexists with one of the most closely monitored active volcanoes in the world.

What remains established at the time of publication is a narrow perimeter: the suspension announced by SAC applies until 3pm on August 15, 2026, the count of around 700 flights covers only the August 8-11 interval, and for the following days the cited sources do not report an updated total. On the duration of the eruptive activity, and thus on the date of return to full operations, no forecast appears in the available sources.
