About the editorShort answer
An airline saying “extraordinary circumstances” does not end the review. Current official EU guidance lists air-traffic-management decisions, political instability, adverse weather and security risks as examples that may qualify. It lists most maintenance-related technical problems, collisions with mobile boarding stairs and internal air-carrier staff strikes as not extraordinary. An external air-traffic-control or airport strike may qualify, but the airline must still prove the link to the disruption and that reasonable measures could not have avoided it. Care, refund and rerouting remain separate questions.
Use the airline’s two-part proof test
An event label is not enough. Current EU guidance says the carrier must show both a causal link between the claimed extraordinary event and this delay or cancellation, and that the disruption could not have been avoided even if all reasonable measures had been taken. Ask for the exact event, the affected flight or rotation, the timeline, and the operational steps taken. Official guidance gives logbook extracts and incident reports as evidence examples. Access to documents can still depend on national rules.
“The airline has to prove this by providing, for example, extracts from logbooks or incident reports.”

Cause matrix: official starting point, not an automatic outcome
Use the carrier's written reason to choose the row, then request the missing evidence. The matrix reflects the European Commission's public guidance checked 29 September 2026. “May qualify” still requires the airline to prove both the causal link and reasonable-measures test for the individual flight.
| Airline reason | Official EU starting point | What to verify |
|---|---|---|
| Air-traffic-management decision, political instability, adverse weather or security risk | May qualify as extraordinary | Exact event, affected flight, causal link and reasonable measures |
| Most technical problems found during maintenance, or caused by failure to maintain | Listed as not extraordinary | Recorded defect, maintenance context and link to the disruption |
| Collision with mobile boarding stairs | Listed as not extraordinary | Incident report and resulting operational timeline |
| Strike by the airline's own staff | Listed as not extraordinary | Who organised the action and which employer's staff were involved |
| External strike affecting the airline, such as air-traffic-control or airport staff action | May qualify as extraordinary | External actor, actual operational effect, causal link and reasonable measures |
What the defence does not automatically cancel
A possible compensation defence does not automatically remove care, refund or rerouting questions. Keep itemised receipts for reasonable meals, hotels and local transport, plus the disruption notice, replacement offer and actual final arrival. Write to the operating airline first. If the explanation is missing or unsatisfactory, the European Commission points passengers to the national authority for the country where the incident took place.
Use the facts before you act
An extraordinary-circumstances label is a position for the airline to explain, not a passenger conclusion. Keep the disruption notice, the actual final arrival, any replacement offer and receipts for reasonable care. Then ask the airline to identify the event, show how it caused this flight's delay or cancellation, and explain which reasonable measures it took. Official examples are a starting classification, not an automatic decision on an individual journey. A reliable request starts with a timeline rather than a conclusion. Compare the scheduled departure and arrival with the actual final arrival, write down when the airline gave notice, and keep any email, app message or airport notice. If an alternative flight was offered, record its proposed arrival and whether you accepted it. If you paid reasonable expenses while waiting, keep the itemised receipt and the reason it was necessary. These facts can support different questions about care, rerouting, refund or a possible statutory framework, but they do not automatically establish every remedy. For a connection, the final ticketed destination and whether all flights were on one booking can be as important as the first disrupted segment. A short departure delay may still create a material final-arrival difference; conversely, an earlier delay does not answer the whole question by itself. For a cancellation, notice timing and the replacement journey should be recorded separately. For denied boarding, distinguish an airline-imposed situation from a voluntary change. A schedule change may need the original itinerary, the revised itinerary and the point at which the passenger was informed. These distinctions help avoid a misleading one-size-fits-all result.
Worked example
Worked example: 1) A passenger's EU departure is delayed more than three hours. 2) The airline writes only that a “technical issue” caused the delay. 3) Current EU guidance says most technical problems found during maintenance or caused by failure to maintain are not extraordinary, so the passenger asks for the recorded defect, its link to this flight and the measures taken. 4) The passenger separately keeps receipts and asks about care, refund or rerouting. The cause still needs evidence; this website does not decide payment.
A practical evidence checklist
Write down the scheduled and actual timing, preserve the airline’s notice, and keep the booking, boarding or check-in proof, replacement offer and reasonable expense receipts. These records help explain what happened to the airline. They are not uploaded to FlightRefundCalc, and the site does not file a claim or decide an outcome.
Keep the legal questions separate
A disruption can create different questions about care while waiting, refund versus rerouting, a possible statutory compensation framework and expenses. An airline’s written explanation may affect one question without deciding all the others. Use official authority guidance and qualified advice for a decision with legal or financial consequences.

Common questions
Does this route page guarantee compensation?+
No. It is an educational framework page. The operating carrier, route, disruption facts, notice, final arrival, rerouting and the airline's written reason can all matter.
Why does the operating airline matter?+
The airline that operated the disrupted flight can be different from the ticket seller or a code-share marketing carrier. Keep the itinerary and disruption notice before you submit a request.
What should I keep?+
Keep booking confirmation, check-in or boarding evidence, the airline notice, scheduled and actual timing, rerouting offers and reasonable expense receipts. Do not upload personal documents to this website.
Where should I send a request?+
Start with the airline's current official channel. Use the free letter toolkit to prepare a factual request, then check the airline's own current instructions before submitting personal information.
Does an extraordinary-circumstances argument cancel meals and hotels?+
Not automatically. Official EU material treats care, refund and rerouting as separate from a possible compensation defence. Keep receipts for reasonable expenses and ask the airline what it will cover.
Is a technical fault always extraordinary?+
No. Current official EU guidance lists most technical problems found during maintenance, or caused by failure to maintain the aircraft, as not extraordinary. Ask for the recorded defect, the causal link and the reasonable measures taken.
Is an airline staff strike extraordinary?+
Current EU guidance says an internal strike by air-carrier staff is not extraordinary. A strike external to the airline, such as action by air-traffic controllers or airport staff, may qualify, but the carrier must still prove the link and the reasonable-measures test.
What evidence can I ask the airline to provide?+
Ask the operating airline to identify the event, explain its link to the delay or cancellation, and show why reasonable measures could not have avoided the disruption. Official EU guidance gives logbook extracts or incident reports as examples of supporting evidence; document-access rules can vary by country.
