Wizz Air extraordinary circumstances: when compensation is refused

What "extraordinary circumstances" actually means

Under Article 5(3) of Regulation (EC) 261/2004 — and the identical retained UK261 rules for departures from the UK — an operating airline is released from paying the fixed compensation in Article 7 if it can show the disruption "was caused by extraordinary circumstances which could not have been avoided even if all reasonable measures had been taken."

Two things follow from that wording, and Wizz Air often glosses over both.

First, the exception is narrow. The Court of Justice has repeatedly said Article 5(3) must be interpreted strictly because it is a derogation from the passenger's normal right to compensation. An event only qualifies if it is not inherent in the normal exercise of the airline's activity and is genuinely beyond its actual control.

Second, "extraordinary" is not enough on its own. Wizz Air must also prove it took all reasonable measures to avoid the disruption — for example by keeping spare aircraft or crew available, or by re-routing you promptly on another carrier. If a reasonable airline could have prevented the knock-on delay, compensation is still due even where the original trigger was outside its control.

What usually does count (compensation can be refused)

These are the situations where a properly evidenced Wizz Air refusal tends to hold up:

• Genuine severe weather — fog, snow, storms or freezing conditions that close a runway or make a departure unsafe. Weather is the classic extraordinary circumstance, confirmed in the reasoning of McDonagh v Ryanair (C-12/11), which arose from the 2010 Icelandic ash-cloud closure.
• Independent air-traffic-control restrictions — flow control, airspace closures or slot restrictions imposed by ATC or the airport, not by Wizz Air.
• Security risks — a credible security threat, a suspicious item, or a required evacuation.
• Bird strike — an impact with a bird is treated as external to the airline's normal operation and can be extraordinary, provided the resulting checks and repairs were handled reasonably.
• Political instability, unrest or unexpected strikes by third parties — for instance a nationwide air-traffic-controllers' strike or airport-staff walkout that is nothing to do with Wizz Air's own workforce.

Even here, remember the two-part test. A morning fog at Luton that clears by 9am does not excuse an evening flight that was actually delayed by a crew shortage. The circumstance must be the real cause of your delay, and Wizz Air must show it could not reasonably have limited the damage.

What does NOT count (compensation is still owed)

This is where most wrongful refusals happen.

Routine technical faults are not extraordinary. In Wallentin-Hermann (C-549/07) the Court held that a technical problem coming to light during maintenance, or through failure to maintain, is inherent in the normal activity of an air carrier and does not release it from paying. Van der Lans v KLM (C-257/14) went further: an unexpected component failure that grounds the aircraft is still part of ordinary operation, because breakdowns are a normal risk airlines must manage. So "technical issue", "aircraft on ground for maintenance" or "unexpected defect" on your Wizz Air notification is generally not a valid reason to withhold compensation.

A strike by Wizz Air's own crew is not extraordinary. In Airhelp v SAS (C-28/20) the Court ruled that industrial action by an airline's own staff is part of the normal exercise of its activity and within its control, so compensation remains payable. If pilots or cabin crew employed by the operating Wizz entity walk out, that is Wizz's problem, not yours.

Operational knock-on effects are not extraordinary. Aircraft rotation problems, late inbound aircraft caused by the airline's own scheduling, crew running out of legal duty hours, or overbooking are all ordinary business risks.

The airline must prove it — you do not

A blunt but important point: you never have to prove the disruption was ordinary. The operating carrier carries the entire burden of showing both that an extraordinary circumstance existed and that all reasonable measures were taken. A one-line email saying "operational reasons" or "weather" with no detail does not discharge that burden.

If Wizz Air refuses, ask in writing for: the specific cause, whether that cause affected your exact flight, and what steps were taken to avoid the delay. Vague answers strengthen your claim. If you still disagree, you can escalate to the relevant regulator — the UK Civil Aviation Authority for flights departing the UK, or the national enforcement body of the departure country in the EU/EEA. Which regime and regulator apply depends on where you took off, which we cover in UK261 vs EU261: which applies to your Wizz flight.

Care and refunds survive, always

Even a valid extraordinary circumstance only removes the fixed compensation. It never removes:

• your right to care under Article 9 — meals and refreshments in proportion to the wait (from 2, 3 or 4 hours depending on distance), plus hotel and transfers if you are stranded overnight; and
• your right to a refund or re-routing under Article 8 if the flight is cancelled or you choose not to travel.

That refund must be paid in money to your original payment method within seven days. A WIZZ credit — usually pitched at 120% of the fare — is only lawful if you actively choose it; Wizz cannot force it on you, and accepting an inconvenient auto-rebooking does not waive your rights.

FAQ

Wizz Air said "operational reasons" — is that an extraordinary circumstance?

No, not by itself. "Operational reasons" usually points to something within the airline's control, such as crewing or aircraft rotation. Ask for the specific cause in writing; if it turns out to be a routine technical fault or an own-crew issue, compensation is still due.

Is a technical fault ever extraordinary?

Rarely. A hidden manufacturing defect flagged by the maker across a fleet, or sabotage, can qualify. But everyday breakdowns and maintenance findings do not — Wallentin-Hermann and van der Lans are clear that these are part of normal operations.

Does bad weather earlier in the day let Wizz off?

Only if that weather actually caused your delay and Wizz could not reasonably have recovered. Weather that has cleared, or that hit a different rotation, is not a valid excuse for a later cancellation caused by something else.

If it really was extraordinary, do I get nothing?

You still get care (meals, refreshments, hotel where relevant) and a full refund or re-routing. Only the fixed Article 7 sum is removed. For the amounts and triggers, see Wizz Air delayed flight compensation and Wizz Air cancelled flight compensation.
