🌩️Severe weather
Violent storms, dangerous winds, heavy fog or significant snow preventing safe take-off or landing.
Understand the rule
What are extraordinary circumstances in air passenger law?
Extraordinary circumstances are events that an airline describes as outside its normal activity and unavoidable even if all reasonable measures had been taken. When this exception applies, the airline may be allowed to refuse EC 261/2004 compensation.
This concept is central in cases involving a flight delay, flight cancellation, missed connection or denied boarding. In practice, many airlines use it very broadly. A vague formula such as “exceptional circumstances beyond our control” is not always enough.
For a refusal to be valid, the airline must show that the cause was genuinely extraordinary, that it directly caused the delay or cancellation, and that no reasonable measures could have avoided the consequences for your trip.
⚖️
Key point: “extraordinary circumstances” do not automatically mean no compensation. Everything depends on the exact reason, the evidence, and how the flight disruption was handled.
Check whether the reason is valid
Many initial refusals can be challenged
Why do airlines invoke extraordinary circumstances?
When a passenger claims compensation for a flight delayed by more than 3 hours, a cancelled flight or a missed connection, the airline often tries to avoid paying the fixed compensation of €250, €400 or €600. Extraordinary circumstances are therefore one of the most common refusal arguments.
If the airline proves that an exceptional event outside its control caused the disruption, it may avoid paying compensation. However, even in that case, it may still have a duty of care: meals, refreshments, hotel accommodation, transport and rerouting.
Why this argument is so common
- It helps the airline dispute EC 261 compensation.
- Passengers do not always know the true cause of the delay.
- Standard replies are often vague.
- Internal problems are sometimes presented as external events.
Why you should verify it
- A routine technical fault is not automatically extraordinary.
- An internal strike is not always exempting.
- Poor aircraft rotation management often falls under internal organisation.
- The airline must prove a direct link to your flight.
Good practice: always ask for the exact cause of the problem. The more precise the reason, the easier it is to assess whether the compensation refusal is legitimate.
When can an airline legally refuse compensation?
To legally refuse compensation on the basis of extraordinary circumstances, the airline must meet several conditions. It is not enough for an event to be unusual: it must actually satisfy the legal criteria.
✅ The event was external to normal airline activity
✅ The event was unavoidable despite reasonable measures
✅ There is a direct link with the affected flight
✅ The airline has concrete evidence
What the airline must show
The precise nature of the incident, its date, its impact on the flight, and the steps taken to reduce the delay, avoid the cancellation or offer suitable rerouting.
What is usually not enough
A vague phrase such as “delay beyond our control”, “operational reasons” or “exceptional circumstances” without specific details.
An automatic refusal does not mean your case is over
Many passengers receive compensation after the real cause is reviewed
Cases often considered extraordinary circumstances
Some events are more often recognised as genuine extraordinary circumstances because they are truly outside the airline’s normal control and may affect safety or the feasibility of the flight.
🗼ATC restrictions
Air traffic control restrictions, airspace closures, slot limitations or decisions imposed by authorities.
🛡️Security risk
Security alerts, serious threats, airport evacuation or major security incidents.
🦅Bird strike
Impact with a bird or another sudden external event requiring safety checks.
Airport or runway closure
If an airport is closed for security reasons, a natural disaster or a serious incident, the airline may argue that it did not control the cause of the delay or cancellation.
Exceptional external crisis
Certain crises, government restrictions, civil unrest or large-scale events may also be considered extraordinary depending on the context.
Important: even in these situations, the airline still has to show that it took reasonable measures to limit the consequences.
Cases often NOT considered extraordinary
Many airlines invoke extraordinary circumstances even though the issue actually relates to their normal operations, aircraft maintenance or internal organisation. In these cases, compensation may still be due.
Often challengeable
- Routine technical fault or normal wear and tear
- Aircraft arriving late from a previous rotation
- Internal organisational failure
- Poor fleet management
- Crew unavailable for predictable reasons
- Staff shortage
What this means for passengers
- The airline’s refusal may be challenged
- The real reason should be checked carefully
- A “technical delay” does not automatically exclude compensation
- A cancellation for “operational reasons” is often debatable
💡
Practical rule: if the problem was caused by normal maintenance, scheduling, aircraft rotation, crew or internal organisation, it is often worth challenging the refusal of compensation.
Technical problems: does the airline still have to compensate you?
This is one of the most important issues. Many airlines refuse compensation by referring to a technical problem, a maintenance issue or an operational incident. However, a technical problem is not automatically an extraordinary circumstance.
When an aircraft suffers a failure related to normal wear and tear, routine maintenance, a defective part or insufficient maintenance, the situation often falls within the airline’s normal activity. In that case, the passenger may still be entitled to compensation under the European regulation.
Technical issue often not exempting
Routine mechanical failure, part replacement, planned maintenance, usual repair or a technical incident without an exceptional external cause.
More complex cases
Damage caused by a sudden external event, bird strike, sabotage or a truly unusual external security incident.
In short: if the airline only says “technical problem”, that is not enough to automatically refuse compensation. You need the exact nature of the fault.
Strikes and extraordinary circumstances: not every case is the same
The issue of strikes is especially sensitive. An airline may sometimes invoke a strike as an extraordinary circumstance, but it depends mainly on who is striking and the airline’s role in the situation.
Strike potentially extraordinary
A strike by air traffic controllers, airport staff external to the airline, or a third-party decision preventing normal flight operations.
Strike often challengeable
An internal strike linked to the airline’s organisation, its employees or internal labour tensions.
In practice, a simple mention of “strike” is not enough. You need to know whether the action involved air traffic controllers, cabin crew, pilots, ground staff or a third-party provider.
Weather, air traffic control and security: when can compensation be excluded?
Adverse weather conditions, air traffic control restrictions, security alerts or the temporary closure of an airport are among the causes most often accepted as extraordinary circumstances. However, everything depends on the actual facts.
🌫️Fog / storm
If conditions make the flight unsafe or impossible under safety guidance, the airline may be exempt.
🛫ATC slots
Limitations imposed by air traffic control authorities may justify a delay or cancellation without compensation.
🚨Security incident
A serious threat, evacuation or security restriction imposed by a competent authority may qualify as extraordinary.
🏢Airport closure
An unexpected runway, terminal or airport closure caused by a major external event may be exempting.
But be careful: if conditions had already improved, if another rerouting option was possible, or if the airline handled the aftermath poorly, parts of the case may still be challengeable.
What evidence should you ask for or keep?
In disputes about extraordinary circumstances, evidence is essential. Passengers do not always have access to internal technical information, but they can still collect many useful elements to challenge a refusal or show the extent of the delay at final destination.
1
Booking
Ticket, e-ticket, booking reference, flight number and full itinerary.
2
Messages received
Emails, SMS or notifications about the delay, cancellation or schedule change.
3
Photos of airport screens
Displayed time, gate information and flight status.
4
Written statement
Try to get a written explanation of the reason given by the airline.
5
Additional expenses
Meals, hotel, taxi, transfers or other disruption-related costs.
6
Final arrival time
Very important, especially in missed connection cases.
📌
Helpful tip: always ask for the exact cause: technical issue, ATC strike, weather, crew, previous rotation, runway closure, security incident, and so on.
What should you do if the airline refuses compensation because of extraordinary circumstances?
If the airline says that your flight delay or cancellation was caused by extraordinary circumstances, do not assume too quickly that you are not entitled to anything. A standard refusal can be challenged, especially if the reason is vague, incomplete or linked to normal operations.
- Ask for the exact and detailed reason for the refusal.
- Check whether the problem was truly external to the airline.
- Verify whether the delay at final destination exceeded 3 hours.
- Keep all evidence: emails, screenshots, expenses, new booking details and actual arrival time.
- Have the case reviewed if the reply seems vague or contradictory.
Even without compensation, you may have other rights
Depending on the situation, the airline may still have to provide care, rerouting, ticket reimbursement, meals, hotel accommodation and associated transport.
Do not confuse compensation with duty of care
Extraordinary circumstances may sometimes exclude the fixed compensation, but they do not automatically remove all the airline’s other obligations.
Did you receive a refusal based on “extraordinary circumstances”?
Check whether that reason is really enforceable
Possible compensation amounts when there are no valid extraordinary circumstances
If the airline cannot prove valid extraordinary circumstances, you may claim compensation under EU Regulation EC 261/2004, depending on the flight distance and the delay at final destination.
Distance
Compensation
Example
≤ 1500 km
€250
Paris → Rome
1500–3500 km
€400
Paris → Marrakech
≥ 3500 km
€600
Paris → New York
In the case of a missed connection, the key factor is usually the delay at final destination on the same itinerary.

Real examples of extraordinary circumstances and challengeable reasons
Example 1: genuinely dangerous weather
An aircraft cannot land safely because of a violent storm and extreme winds. The flight is cancelled. The airline may invoke extraordinary circumstances, provided it then offers proper care and rerouting.
Example 2: ordinary technical fault
The airline refers to a maintenance issue or defective part. If the problem falls under normal aircraft maintenance, compensation may still be due.
Example 3: air traffic controllers’ strike
Traffic is severely restricted by air traffic control. The cause is external to the airline; compensation may be excluded, but care is still often due.
Example 4: previous aircraft rotation delayed
Your aircraft arrives late from a previous flight and your departure is pushed back. This often falls under the airline’s organisation and may be challenged.
FAQ – Extraordinary circumstances and flight compensation
What are extraordinary circumstances for a flight?
These are events outside the airline’s normal operations, unforeseeable or unavoidable despite reasonable measures. They may sometimes exclude EC 261 compensation, but they must be proven precisely.
Can an airline refuse compensation with only a standard formula?
Not necessarily. A vague reply such as “exceptional circumstances” or “reasons beyond our control” is not always enough. The exact reason, the evidence and the way the disruption was handled all matter.
Is a technical problem an extraordinary circumstance?
Not automatically. Routine technical faults, normal wear and tear or maintenance issues often fall within the airline’s normal operations. In that case, compensation may still be due.
Does bad weather always exclude compensation?
No. You have to distinguish genuinely dangerous conditions from a general disruption. The airline must show that weather actually prevented safe operation of the flight.
If there is a strike, can I still get compensation?
It depends on the type of strike. An external strike, such as one involving air traffic controllers, is more likely to be considered extraordinary. An internal airline strike may be more challengeable.
Does the airline still have to assist me in extraordinary circumstances?
Very often yes. Even if fixed compensation is not due, the airline may still have to provide care, meals, hotel accommodation, transport and rerouting depending on the situation.
How much compensation can I get if the refusal is unjustified?
Compensation under the European regulation can be up to €250, €400 or €600 per passenger, depending on the flight distance and the applicable conditions.
Which documents are useful to challenge a refusal?
Your booking, boarding passes, airline emails, delay screenshots, receipts for extra expenses and any written statement showing the exact cause of the problem.
How can I tell whether the airline is abusing this argument?
If the reason is vague, changing, contradictory or clearly related to maintenance, crew, aircraft rotation or internal organisation, it may be worth challenging.
Your case deserves a real review
Did the airline refuse your claim by invoking extraordinary circumstances?
This reason is not always valid. Many passengers give up even though their flight delay compensation or flight cancellation compensation may still be possible. Have your case, the real reason for the refusal, and your rights under EU Regulation EC 261/2004 reviewed.
