What Are Extraordinary Circumstances in Air Travel?
Under EU Regulation EC 261/2004, airlines must compensate passengers for cancellations, delays over 3 hours, and denied boarding — except when the disruption is caused by extraordinary circumstance.
These are events outside the airline’s control that could not have been prevented even if the airline took all reasonable steps. Examples include severe weather (storms, fog, volcanic ash), air traffic control restrictions, airport closures, security threats, bird strikes, or sudden medical emergencies on board.
Key Point: In such cases, passengers are not entitled to cash compensation, but airlines still have a duty to provide care such as meals, refreshments, accommodation, and rebooking.

What Support Am I Entitled to During Extraordinary Circumstances?
Even when airlines are exempt from paying financial compensation, passengers retain strong rights under EU law. Airlines must provide:
- Meals and refreshments during long waits.
- Two free communications (calls, emails, or texts).
- Hotel accommodationif the disruption causes an overnight delay.
- Transport between the hotel and airport.
- Rebooking on an alternative flight or a full ticket refundif the flight is cancelled or delayed more than 5 hours.
This means that while extraordinary circumstances may block compensation, you will never be left stranded without care or alternative travel.
When Airlines Are Typically Not Obliged to Pay Cash Compensation
(But must still provide care, rebooking, or ticket refund under EU Regulation 261/2004)
Legal Foundation:Article 5(3) of Regulation (EC) No 261/2004 provides that an operating air carrier is not obliged to pay compensation (under Article 7) if it can prove that the cancellation or long delay was due to “extraordinary circumstances” which could not have been avoided even if all reasonable measures had been taken.
Below are common categories where airlines may claim exemption from cash compensation, along with explanations and source references:
-
Severe Weather Events (storms, heavy snow, fog, lightning, ash clouds)
- Why no compensation: Weather is generally considered an “extraordinary circumstance” beyond the airline’s control.
- Must still provide: rebooking or refund, meals/refreshments, communications, hotel + transfers if overnight.
- Source / legal basis: Recital 15 of EC 261 mentions air traffic management and extreme weather as potential extraordinary elements. Regulation (EC) No 261/2004
-
Air Traffic Control Restrictions or ATC Strikes
- Why no compensation: ATC decisions and constraints are outside the airline’s operational control.
- Must still provide: care, rebooking or refund.
- Source / legal basis: The definition of “extraordinary circumstances” in EC 261 explicitly includes air traffic management decisions. Regulation (EC) No 261/2004
-
Airport Closure or Runway Closure / Obstruction
- Why no compensation: If airport infrastructure fails (runway unusable, closure by authorities), airlines cannot operate flights.
- Must still provide: all care and rebooking/refund.
- Source / legal basis: ECJ jurisprudence considers such airport-operator conditions as within extraordinary circumstances (e.g., runway obstruction in C-159/18 Moens) Regulation (EC) No 261/2004
-
Airspace Closure / Government Restrictions / Military Measures
- Why no compensation: When national authorities close airspace or restrict traffic, airlines have no control over that.
- Must still provide: care + rebooking/refund.
- Source / legal basis: Recognized in interpretations of extraordinary circumstances in EU law (and recitals). Regulation (EC) No 261/2004
-
Natural Disasters / Major Environmental Events (volcanic ash, earthquakes, floods)
- Why no compensation: These are force majeure events beyond airline control
- Must still provide: care and transport options.
- Source / legal basis: ECJ rulings (e.g., McDonagh, volcanic ash in 2010) accepted volcanic ash as extraordinary. Regulation (EC) No 261/2004
-
Security Incidents, Terrorism, Bomb Threats, Airport Lockdowns
- Why no compensation: These are security or safety events outside airline control.
- Must still provide: rebooking/refund + care.
- Source / legal basis: Courts treat security closures as extraordinary circumstances in EU jurisprudence. Regulation (EC) No 261/2004
-
Strikes by Third Parties (airport staff, ground handlers, fuel suppliers)
- Why no compensation: These strikes are external to the airline’s control.
- Must still provide: care + rebooking/refund.
- Source / legal basis: The interpretation of “extraordinary circumstances” includes third-party industrial actions. The airline must show it took all reasonable measures. Regulation (EC) No 261/2004
-
Bird Strikes / Wildlife Collisions
- Why no compensation: A bird strike is treated by the ECJ as an extraordinary event, because it is external to aircraft systems and not inherent to the airline’s normal operations.
- Must still provide: care + rebooking/refund.
- Source / legal basis: CJEU ruling (Pešková / Pesková) held that bird strikes constitute extraordinary circumstances under EC 261. Regulation (EC) No 261/2004
-
Onboard Medical Emergencies / Health Crises (e.g. passenger heart attack)
- Why no compensation: Such emergencies are sudden and beyond airline control, requiring safety diversion.
- Must still provide: care, rebooking/refund, handling under safety procedures.
- Source / legal basis: Considered a safety / medical exception in airline operations; airlines must still comply with passenger rights obligations, but compensation is not due in typical interpretations. (No direct regulation article but consistent with extraordinary circumstances doctrine.) Regulation (EC) No 261/2004
-
Safety or Regulatory Grounding Orders / Mandatory Inspections
- Why no compensation: If authorities ground a plane for unexpected safety defects or regulatory orders, airlines cannot proceed.
- Must still provide: care + rebooking/refund.
- Source / legal basis: ECJ jurisprudence includes regulatory orders or authority-mandated safety shutdowns as extraordinary in some cases. Regulation (EC) No 261/2004
-
Sabotage, Acts of Terrorism, Vandalism
- Why no compensation: These are external, unforeseeable, and beyond airline control.
- Must still provide: rebooking/refund and care.
- Source / legal basis: Recognized in case law as permissible extraordinary circumstance. Regulation (EC) No 261/2004
-
Air Navigation Service Provider Failures / ATM IT Outages
- Why no compensation:Failures of systems owned by air navigation providers are external to the airline’s normal operations.
- Must still provide:care + rebooking/refund
- Source / legal basis:Derived from the doctrine of external events and interpretations of extraordinary circumstances. Regulation (EC) No 261/2004
-
Supplier Failures (Fuel supply disruptions by third parties)
- Why no compensation:If fuel or supplies fail through third-party fault outside airline control, it may be extraordinary.
- Must still provide:care + rebooking/refund
- Source / legal basis:In legal commentary, supplier failures fall under external extraordinary events. Regulation (EC) No 261/2004
-
Chain Effects from a Prior Extraordinary Event
- Why no compensation:If an earlier extraordinary event causes cascading disruptions, airlines may claim the link as a valid extraordinary circumstance, but must prove the causal chain and reasonable steps taken.
- Must still provide:care + rebooking/refund
- Source / legal basis:ECJ and guidance texts accept chain causation but stress burden of proving link and measures. Regulation (EC) No 261/2004
-
Some External Technical Failures (not routine)
- Why limited compensation: Routine technical or mechanical faults (wear-and-tear, routine maintenance issues) are not considered extraordinary (Wallentin-Hermann case). But if a technical defect arises from sabotage, hidden manufacturing defect, or external cause, the airline may be exempt.
- Must still provide:care + rebooking/refund.
- Source / legal basis:The Wallentin-Hermann C-549/07 case established that technical problems which are inherent are not extraordinary. Regulation (EC) No 261/2004
Key Principle: Airline Responsibility / Burden of Proof
-
The airline must prove both that the event was:
- Not inherent in its normal operations (i.e., external); AND
- Unavoidable even if all reasonable measures had been taken.
(These two criteria are cumulative and evaluated case-by-case).
- If the airline fails to prove these, cash compensation is due. Even within extraordinary events, the airline must still comply with its obligations to care and rebooking/refund. Regulation (EC) No 261/2004
