“Extraordinary circumstances” are events outside an airline’s control that it could not have avoided even with all reasonable measures — think severe storms or air-traffic-control shutdowns. When a genuine extraordinary circumstance causes an extraordinary circumstances flight delay or cancellation, the airline does not have to pay cash compensation. But it still owes you care and a refund or rerouting, and airlines lean on this excuse far more often than the law actually allows.

If your claim was waved away with this phrase, don’t assume it’s the end of the road. Check Your Compensation to see whether your delay really qualifies.

What “extraordinary circumstances” actually means

The phrase comes straight from EU Regulation 261/2004. To escape paying compensation, an airline has to clear two hurdles, not one. First, the cause must be genuinely outside its control. Second, it must show it took every reasonable step to avoid the disruption. Failing either test means compensation is still due.

Crucially, the burden of proof sits with the airline. You don’t have to prove the delay was avoidable — they have to prove it wasn’t. That detail decides a surprising number of disputes.

What counts as an extraordinary circumstance

Some events are clearly beyond an airline’s control. When these genuinely cause your disruption, cash compensation usually isn’t payable:

• Severe weather — storms, heavy snow, fog or volcanic ash that make safe operation impossible.
• Air-traffic-control restrictions — slot limits or airspace closures imposed by authorities.
• Security risks — credible threats, sabotage or unrest at the airport.
• Political instability — conflict or government action affecting the route.
• Bird strikes — confirmed by the EU’s top court in the Pešková case (C-315/15) as outside the airline’s control.

In these situations the airline must still look after you. A weather event that grounds your flight does not switch off your right to meals, a hotel for an overnight wait, or a refund. If bad weather hit your trip, our guide to a flight cancelled due to weather explains exactly what you keep.

What does NOT count — even if the airline says so

This is where most wrongful rejections happen. The following are within an airline’s control, so compensation generally is due:

The pattern is simple: problems that come from how the airline runs its own business are its responsibility. A technical fault discovered during maintenance, a rostering gap, or a delay that cascades from an earlier leg are all ordinary operating risks — not extraordinary events.

Why airlines overuse the excuse

Rejecting a claim costs an airline nothing upfront, and many passengers give up after a single “no”. So “extraordinary circumstances” is sometimes used as a blanket response, even when the real cause was a mundane technical issue or a staffing gap.

A vague rejection email is not proof. If the airline can’t point to a specific, documented cause that genuinely sat outside its control, the rejection may not hold up. Knowing the delayed flight compensation amount at stake — up to €600 per person — is often reason enough to push back rather than walk away.

Your rights even when it really is extraordinary

Even in a genuine extraordinary circumstance, two rights never disappear:

• The right to care — meals, drinks, communication, and a hotel plus transfers for an overnight delay. The amount of food or nights involved doesn’t cap this duty.
• The right to a refund or rerouting — if your flight is cancelled, the airline must offer your money back within seven days or an alternative flight. A flight cancelled for weather still triggers this choice.

What changes in a true extraordinary circumstance is only the cash compensation — the fixed €250–€600 payment. Everything else stands.

It’s also worth remembering that denied boarding is treated differently. There is no extraordinary-circumstances defence for bumping a passenger off an oversold flight, which is why denied boarding compensation claims are among the hardest for airlines to refuse.

Rejected with “extraordinary circumstances”? Do this

If you’ve been turned down, take these steps:

1. Ask for the specific reason in writing. A general phrase isn’t enough — request the documented cause.
2. Check what really happened. Weather archives and flight-tracking history often show other aircraft operating the same route at the same time, which undercuts a weather excuse.
3. Escalate. You can complain to the national enforcement body for the country you departed from, or hand the case to specialists.

Challenging an airline’s legal team is daunting on your own. Because FlyHelp works on a no win no fee delayed flight basis, you can have experts re-examine and re-fight a rejected claim with no upfront cost — you only pay a success fee if money is recovered.

Not sure whether your delay was genuinely extraordinary? Check your compensation — it’s free and takes a couple of minutes.

Frequently Asked Questions

Is bad weather always an extraordinary circumstance?

Not automatically. Severe weather that genuinely prevents safe flight — storms, dense fog, heavy snow — usually does count. But airlines must prove the weather actually affected your flight and that no reasonable measure could have avoided the delay. If other aircraft operated your route at the same time, or the real cause was a knock-on delay, you may still have a valid claim.

Is a technical fault an extraordinary circumstance?

Generally no. The EU’s top court ruled in the van der Lans case (C-257/14) that routine technical and mechanical problems are part of normal airline operations, so they do not count as extraordinary. Airlines are expected to maintain their fleet, and a sudden fault rarely excuses them. Hidden manufacturing defects flagged by a manufacturer are a narrow exception.

My claim was rejected as ‘extraordinary circumstances’ — can I challenge it?

Yes, and you should if the cause looks ordinary. Ask the airline for the specific, documented reason, then check weather and flight-tracking records for the day. Many rejections collapse under scrutiny. You can escalate to the national enforcement body or use a no-win-no-fee specialist to reopen the claim at no upfront cost.
