Extraordinary circumstances under EU261 and UK261 explained — what counts, what does not, how airlines argue it and how to respond without self-rejecting a valid claim.

- Examples often accepted include severe weather making safe operation impossible, air-traffic control restrictions beyond airline control, political instability…
- Yes — EU261 care duties (refreshments, communication, hotel when overnight) can apply during long delays even when extraordinary circumstances remove the cash band.

- Extraordinary circumstances can block cash compensation but not always care.
What are extraordinary circumstances under EU261?
Extraordinary circumstances are events outside an airline's control that could not have been avoided even if all reasonable measures had been taken — Regulation EC 261/2004 Article 5(3). When they genuinely apply, standardised cash compensation may not be due, though care duties (meals, hotels) can still apply during the wait.
Airlines frequently cite extraordinary circumstances in template rejections. COURT OF JUSTICE OF THE EU case law has narrowed some defences — airline-internal strikes and many technical faults have been held not extraordinary. Do not abandon a claim because the first email says "weather".
Deep rules: EU261 compensation complete rules. Strike nuance: airline strikes passenger rights.
What typically counts as extraordinary circumstances?
Examples often accepted include severe weather making safe operation impossible, air-traffic control restrictions beyond airline control, political instability, security risks and some bird strikes — always fact-specific. Airline staff strikes organised by the carrier's own employees have often been held within airline control in CJEU case law.
The airline must prove the event and that reasonable measures could not have prevented the delay. A generic "operational reasons" letter is not proof.
| Event type | Often extraordinary? | Passenger move |
|---|---|---|
| Severe weather closing airport | Often yes for cash | Still claim care expenses |
| Airline crew strike (internal) | Often no (CJEU) | Claim compensation bands |
| Hidden manufacturing defect | Often no | Cite case law in reply |
| ATC flow restriction | Often yes | Document official NOTAM if possible |
| Technical fault on routine maintenance | Often no | Challenge template rejections |
Can you still get care when compensation is blocked?
Yes — EU261 care duties (refreshments, communication, hotel when overnight) can apply during long delays even when extraordinary circumstances remove the cash band. Keep meal and hotel receipts. See [EU261 care and assistance rights](/guides/eu261-care-and-assistance-rights).
Care and compensation are separate entitlements. Airlines sometimes pay neither unless pressed.
Extraordinary circumstances — verdict
Verdict: treat airline extraordinary-circumstances letters as opening arguments, not final answers. Gather facts, cite regulation, escalate to the national enforcement body. Not for passengers who already received correct payment — this page is for disputed rejections.
