Your flight was delayed or cancelled. The airline's chatbot denied your compensation claim citing "extraordinary circumstances." Here is what that means, when it is a valid defence, and how to push back.
What EU261 Covers
EU Regulation 261/2004 applies to: EU261
- All flights departing from an EU airport (any airline)
- Flights arriving at an EU airport operated by an EU-based airline
- UK flights under the retained UK version of EU261 (post-Brexit)
You are entitled to compensation for:
- Delays of 3+ hours at final destination
- Cancellations where you were not notified at least 14 days in advance
- Denied boarding due to overbooking
Compensation Amounts
| Flight type | Compensation |
|---|---|
| All flights up to 1,500 km | €250 |
| All intra-EU flights over 1,500 km | €400 |
| Non-intra-EU flights between 1,500 and 3,500 km | €400 |
| Non-intra-EU flights over 3,500 km | €600 |
Compensation can be reduced by 50% if the airline offers rerouting and you arrive within 2–4 hours of your original time (depending on distance). The amount you get is set by Article 7 of the Regulation; the airline cannot reduce it below this floor by citing internal policy.
When "Extraordinary Circumstances" Is a Valid Excuse
Airlines can avoid paying compensation if the delay or cancellation was caused by extraordinary circumstances they could not have avoided even with all reasonable measures. Valid examples:
- Severe weather that makes flying unsafe (not just inconvenient)
- Air traffic control strikes
- Security incidents affecting the airport
- Political instability at the destination
When It Is NOT Extraordinary
Airlines routinely claim extraordinary circumstances when the situation does not qualify. Common invalid claims:
- Technical faults — the European Court of Justice ruled that technical problems are part of normal airline operations and are not extraordinary circumstances unless caused by a hidden manufacturing defect.
- Staff shortages or strikes by the airline's own staff — not extraordinary if foreseeable or caused by the airline's own actions.
- Late inbound aircraft — if the previous delay was caused by a non-extraordinary event, it does not become extraordinary in a chain.
- Light turbulence or routine weather — airlines must plan for ordinary weather. Only genuinely exceptional conditions qualify.
The burden of proof is on the airline. They must provide specific evidence of the extraordinary circumstance and demonstrate they took all reasonable measures. A general claim of "operational disruption" is not sufficient.
How to Challenge the Denial
- Ask the airline to specify the exact extraordinary circumstance and provide documentation (e.g. weather report, ATC communication)
- If technical fault: cite the ECJ ruling that technical faults are not extraordinary circumstances (Case C-549/07 Wallentin-Hermann)
- If they do not respond within 6 weeks, escalate to your National Enforcement Body (NEB)
Escalation: National Enforcement Bodies
- Germany: Luftfahrt-Bundesamt (LBA)
- France: Direction Générale de l'Aviation Civile (DGAC)
- UK: Civil Aviation Authority (CAA)
- Ireland: Commission for Aviation Regulation (CAR)
- Spain: Agencia Estatal de Seguridad Aérea (AESA)
Frequently Asked Questions
Does "non-refundable" mean no refund when the airline cancels?
No. EU Regulation 261/2004 requires a full refund when the airline cancels, regardless of fare type.
What counts as extraordinary circumstances for EU261?
Events like severe weather or air traffic control strikes. Technical faults and staffing issues are generally not extraordinary.
Who enforces EU261 flight compensation claims?
Your National Enforcement Body (NEB) — e.g. CAA in the UK, Luftfahrt-Bundesamt in Germany. Filing is free.
