Your Flight Was Cancelled by Volcanic Ash. Here Is What You Are Owed

Regulation 261/2004 does two separate jobs, and nearly every argument at a service desk comes from treating them as one.

The first is compensation: a fixed cash sum for the nuisance of having your plans wrecked. The EU's own passenger rights pages set it at 250 euros for flights of 1,500 km or less, 400 euros for flights over 1,500 km inside the EU and for other flights between 1,500 and 3,500 km, and 600 euros above 3,500 km. If you accept re-routing and arrive late but not catastrophically so, those can be halved to 125, 200 and 300.

The second is assistance, which the regulation calls the right to care, plus the right to get where you were going or get your money back. In practice: food and drink while you wait, a hotel if you are rebooked onto the next day, transport to that hotel and back, and two phone calls or emails. Separately, a one-off choice between a refund of the ticket and re-routing to your destination at the earliest opportunity, or on a later date you pick.

Here is the part that matters. An eruption that closes airspace is an extraordinary circumstance. The EU's guidance lists air traffic management decisions and adverse weather among its examples, and an ash cloud is both. So the first entitlement, the cash, is gone.

The second one is not. It does not shrink, it does not pause, and the volcano is not a defence against it. Airlines have argued otherwise, in court, and lost.

In April 2010 the Eyjafjallajokull eruption closed much of European airspace for days. Denise McDonagh's flight from Faro to Dublin was cancelled, Ryanair declined to give her the care the regulation requires, and she sued. The case reached the Court of Justice of the European Union as C-12/11, and the judgment came on 31 January 2013.

The airline's argument was ambitious and, read generously, not absurd: an ash cloud grounding a continent is so far beyond ordinary disruption that it must sit in a category of its own, one where an airline cannot reasonably be expected to keep buying hotel rooms for an open-ended number of nights. Call it super-extraordinary, and the duty of care switches off.

The Court declined. Yes, the closure of part of European airspace caused by the eruption counts as an extraordinary circumstance. No, that does not release the carrier from the obligation to provide care. There is no separate tier above extraordinary where the obligation stops.

Two practical things follow, and they are the reason this ruling is worth knowing by name.

The first is that the obligation has no published ceiling in euros and no published cut-off in days. It runs while you are waiting. In 2010 that meant, for some people, the better part of a week.

The second is the catch. The recoverable amount is what was necessary, appropriate and reasonable, judged afterwards and case by case. That is not a blank cheque, and the suite at the airport hotel is unlikely to survive the test. It also means the practical route to being made whole is unglamorous: ask the airline for care at the desk, in writing if you can, and when it is not forthcoming, buy modestly and keep the paper. A receipt for a 40-euro room is a document. A memory of a bad night is not.

The flight is the part with a regulation behind it. The excursion is not, and this is where our own catalogue turns out to be the most useful document available.

We read the booking conditions attached to the four most-reviewed Etna summit crater tours on this site, the same four listed at the foot of this article, carrying between them more than 1,400 reviews. All four are sold with free cancellation. The wording differs slightly between operators and the substance does not:

• "Full refund when the booking is cancelled at least 24 hours before departure."
• "The full amount is refunded on a cancellation made at least 24 hours before departure."
• "The whole amount is refunded when the cancellation reaches the operator 24 hours before departure."
• "Cancellations at least 24 hours ahead of the scheduled departure are refunded in full."

Read those again and notice who is doing the cancelling. Every one of them describes you pulling out. That is what free cancellation means on a volcano, and it is a genuinely good term: twenty-four hours is enough notice to react to a bulletin.

Now read what the same four operators say about themselves. One states that every excursion runs in accordance with the current volcanic risk levels. Another says the itinerary can change according to what the volcano is doing or what the weather allows. A third warns that the guide, having assessed the weather and the state of the volcano, may at their sole discretion cut the time at altitude short and bring the group down. The fourth is the most explicit of the set:

The same operator adds that excursions run within the limits of whatever ordinance is in force, and that the guides have to stop wherever it is still safe to stop.

None of that is sharp practice. It is the only honest way to sell a walk on an active volcano, and an operator who promised the summit in all conditions would be the one to avoid. But line the two halves up and the asymmetry is plain. Your right to cancel is written down with a number attached. Their right to cancel is written down with no number attached at all. Not one of the four says what happens to your 55, 65, 70 or 115 euros when the guide turns the group around at 2,800 metres, or when the ordinance moves the ceiling below the crater you booked to stand on.

In practice the money usually comes back, because the booking platforms have their own policies sitting above the operator's and because an operator who kept the fare would not hold 4.9 stars for long. The point is that it is a practice rather than a term. And a shortened day is the harder case: you went up, you walked, you saw less than the listing showed. There is no clause for that anywhere, and asking afterwards is a negotiation, not a claim.

The separate costs are the ones that catch people out. On these four tours the cable car and jeep tickets are frequently excluded from the fare and paid in cash on the spot, at 45, 50 or 65 euros a head depending on the operator, and one of them charges 70 euros instead of 50 to anyone who decides mid-excursion to come back down by bus. Those are transactions with the lift company, not with the tour operator, and they sit outside whatever refund the operator offers. Our guide to choosing a volcano tour goes through the rest of what the headline price tends to leave out.

The most common ruined volcano day involves no eruption, no ash and no closure. You get up at three in the morning, you pay, you arrive, and the thing you came for is inside a cloud.

Haleakala, on Maui, sells a sunrise reservation for one dollar per vehicle, on top of the park entry fee, and it is the clearest published example of how this works because the park says the quiet part out loud. Its official FAQ answers the question "Can I get a refund or exchange for a different day?" with a flat "No, your sunrise reservation is good for one day only." The reservation can only be used on the date printed on it. And on the matter of whether you will see anything, the park is disarmingly frank: "we can't predict whether a sunrise is going to be clear or cloudy."

So the National Park Service sells you a timed slot for a natural phenomenon it openly says it cannot forecast, and tells you in advance that the dollar is gone either way. That is not a scandal. At a dollar it is barely a transaction, and the reservation exists to ration a small car park rather than to sell a sunrise. But it is the honest shape of the deal, and almost nothing else in this industry states it as plainly.

The same logic, with more money attached, runs through every crater viewpoint, every summit lift and every sunrise trek on the market. What you are buying is access at a time, not a view. Weather is not a failure of the service.

Almost every page on the internet about volcanoes and insurance is written by somebody selling a policy. We did not read any policy wording at source for this article, so what follows is structural: the two clauses to go and find in your own schedule.

The first is the known event rule. Cover generally has to be bought before a peril becomes foreseeable, and once an eruption is under way and in the news, a policy taken out afterwards will usually not respond to disruption from it. The awkward part is specific to volcanoes: one can stay in the news for months, and insurers do not agree with each other about when a long-running eruption stops being new and becomes known. If the mountain you are booking is currently doing something, put that question to the insurer in writing before you pay.

The second is altitude. Standard policies cover trekking only up to a stated height, and the ceiling is frequently lower than what people book: several of the summit itineraries on this site finish above 3,300 metres, and a policy that stops at 3,000 does not quietly stretch. The point at which you discover that is the point at which you need a helicopter. The number sits in the schedule under hazardous activities and takes a minute to find.

Four gaps, stated rather than papered over, because how we work depends on saying so.

The regulation in its own words. Every attempt to open the consolidated text of Regulation 261/2004 on the EU's legal database on 13 October 2026 came back empty behind an automated-traffic challenge, and the Court's judgment viewer needs a browser session we do not have. The figures above therefore come from the European Commission's public passenger rights pages, which are official but are a summary, and the holding in McDonagh from the EU Fundamental Rights Agency's case-law database rather than the judgment text. Anyone arguing a real claim should read the articles themselves.

Poas. Costa Rica's crater was going to be the second example of the no-refund-for-cloud rule, which is widely reported for that park. The Costa Rican parks authority returned a 503 on 13 October 2026, and the accounts we found in its place disagree with each other while the most detailed is years old. So it is not here, and Haleakala is, because its park service publishes the rule itself.

Insurance wordings. Not read at source. No figure or percentage is attached to either clause above, because the numbers in circulation come from brokers and comparison sites.

Etna's state as you read this. The most recent INGV weekly bulletin when this was written was dated 6 October 2026, and we have not opened it, so nothing here says what the volcano is doing today. That is deliberate: a blog post is the wrong place for a live alert level, and checking it yourself takes two minutes. For what you would actually see if you went, our piece on where lava is visible now explains why the honest list is shorter than the market suggests.

One caution that is not a gap: operator conditions change without notice, and the four sets quoted here were read on a single day. The asymmetry will outlast the wording.
