Mount Etna’s ash cloud shut Catania airport again, here’s what your airline actually owes you

Mount Etna erupted strongly enough overnight into 26 September 2026 to push an ash cloud roughly 4km high over eastern Sicily, and Catania–Fontanarossa airport — Italy’s fifth-busiest by passenger traffic — suspended all arrivals until 1000 GMT (12:00 local time) on Sunday 27 September. If you are booked through Catania this weekend, here is the one thing worth knowing before you call your airline: volcanic ash counts as an ‘extraordinary circumstance’ under EU261 and UK261, so cash compensation is very unlikely — but the airline still owes you care and a way to your destination.

What actually happened at Catania airport

A violent overnight storm combined with ash drifting south from Etna’s North-East crater to shut down normal operations in two stages. Controllers first cut arrivals to four a hour — a third of the airport’s usual 12 — as the plume crossed the approach paths, then suspended arrivals entirely once INGV measured the cloud at around 4km and raised the aviation alert to red. Ten flights were diverted before the full suspension: five to Palermo, three to Trapani and two to Comiso. Catania handles roughly 10 million passengers a year, and this is not an isolated event — Etna’s ash has forced repeated restrictions here through July, August and now September 2026.

What EU261 and UK261 actually say about volcanic ash

Both rules say the same thing: volcanic ash, alongside air traffic control strikes and severe weather, is an ‘extraordinary circumstance’, so the airline does not owe the usual €250–€600 (£220–£520) per-passenger payout. That classification survived its biggest test in 2010, when an Icelandic volcanic eruption grounded most of European airspace for six days — regulators and courts subsequently confirmed an ash-cloud closure is exactly the kind of event the extraordinary-circumstances clause was written for.

What does not change is the airline’s duty of care. Whatever caused the disruption, a cancelled or badly delayed passenger is still owed meals and refreshments while they wait, a hotel and transport if an overnight stay is needed, and a route to their final destination — either rebooking on the next available flight or a full refund.

What you can still claim, even when cash compensation is off the table

The extraordinary-circumstances clause only removes the fixed cash sum. Everything else on the airline’s duty-of-care list still applies, and it is worth knowing the difference before you argue with a check-in desk.

Keep every receipt for meals, transport and accommodation you pay for yourself — airlines will reimburse reasonable costs against a receipt even when they cannot arrange a hotel directly, and a claim backed by paperwork moves faster than a verbal account after the fact.

What this means if you are flying through Sicily this week

If your flight touches Catania before Sunday afternoon, check your airline’s app before you leave for the airport rather than trusting the departure board once you arrive — Etna’s ash has closed and reopened Catania several times this year, sometimes within the same day. Ask explicitly for rerouting if your flight is cancelled outright; airlines are required to offer it but do not always volunteer it. A separately booked connecting flight elsewhere is not protected the same way a single ticket is, so if you booked Catania-to-somewhere-else on two separate tickets, the second one is your own risk to manage.

Common questions about the Etna disruption

Will Mount Etna keep disrupting Catania flights?

Likely, at least through this eruptive phase. Etna has forced repeated ash-related restrictions at Catania across July, August and September 2026, and the airport operator has become practised at the capacity-cut-then-suspend pattern used this weekend.

Does travel insurance cover the costs the airline will not?

Check your policy’s travel delay section — some plans pay a fixed daily amount once delay hours pass a set threshold, regardless of what the airline provides, which can cover incidentals the airline’s duty of care does not stretch to.

What if my missed connection was on a different ticket?

Rerouting and refund rights apply to the ticket that was disrupted, not to a separately booked onward flight — two separate tickets means the second airline owes you nothing for a delay caused by the first.

A grounded flight is a reminder that nature runs on its own schedule, not an airline’s — it is the same lesson in the Himalaya, which is why our Everest Base Camp itineraries build in spare days for exactly this kind of disruption.
