Wizz Air compensation claim rejected: what to do next

Why Wizz rejects claims that are actually valid

Under Regulation (EC) 261/2004 (and its retained UK version, UK261), the operating carrier owes a fixed sum when it disrupts your flight and has no lawful excuse. The amounts depend on distance: EUR 250, EUR 400 or EUR 600 for EU/EEA departures, or GBP 220, GBP 350 or GBP 520 for UK departures. A long delay is treated like a cancellation for compensation purposes once you land 3 hours or more late (Sturgeon C-402/07; Folkerts C-11/11 confirmed that the delay is measured at the final destination).

The airline can avoid paying only if it proves "extraordinary circumstances" that could not have been avoided even with all reasonable measures (Art. 5(3)). The key word is proves. In practice, many first-round rejections rely on a label rather than proof: "operational reasons", "aircraft rotation", "unexpected technical issue", or a bare assertion of weather with no detail. None of those is automatically a valid defence.

The case law that beats a weak rejection

Before you write back, know which excuses do not hold up:

• A routine technical or mechanical fault is not extraordinary. The Court of Justice made this clear in Wallentin-Hermann (C-549/07) and again in van der Lans (C-257/14): defects that arise in the normal course of operating aircraft are part of the airline's ordinary activity.
• A strike by the airline's own crew is not extraordinary, and compensation is still due (Airhelp v SAS, C-28/20).
• The operating carrier is the one that owes you (Wirth C-532/17). Wizz operates through separate entities — Wizz Air Hungary, Wizz Air Malta, Wizz Air UK and Wizz Air Abu Dhabi — so make sure you address the entity that actually operated your flight.

By contrast, genuinely independent events usually are extraordinary: severe weather, air traffic control restrictions imposed by others, or airport-wide closures (see McDonagh C-12/11 on the scope of the airline's duties during such events). Even then, the burden is on Wizz to show the event happened, that it hit your specific flight, and that it took all reasonable steps to limit the delay.

How to reply in writing

Keep it factual and firm. A short letter or email that does the following is enough:

1. Restate the facts. Flight number, date, route, scheduled and actual arrival times, and how late you reached your final destination.
2. State the entitlement. Name the regime (EU261 for an EU/EEA departure, UK261 for a UK departure) and the amount you claim. If you are unsure which applies, our note on UK261 vs EU261 — which applies explains that the departure airport decides.
3. Reject the vague reason. Say plainly that "operational reasons" is not a recognised defence and that a routine technical fault does not remove the right to compensation, citing Wallentin-Hermann and van der Lans.
4. Demand evidence. Ask Wizz to disclose the precise cause, with supporting documents — technical logs, the specific ATC or weather notice (a METAR/TAF or a NOTAM), or the crew-rostering record. If they claim weather or ATC, ask why other flights operated and what measures they took.
5. Set a deadline. Give a reasonable period (for example 14 days) to pay or to provide the evidence, and say you will escalate otherwise.

Send it to the operating Wizz entity, keep copies, and reference your original claim number.

Keep compensation separate from your other rights

A rejection of compensation does not touch your other entitlements, and you should claim them separately:

• Refund or re-routing (Art. 8). If your flight was cancelled, you can choose a full refund in money to your original payment method within 7 days, or re-routing. A WIZZ credit — often offered at 120% — can never be forced on you in place of cash, and accepting it should never be a condition of your compensation claim. See refund vs WIZZ credit.
• Care (Art. 9). Meals, refreshments and, where needed, hotel accommodation apply once waiting times reach 2, 3 or 4 hours. This is owed even in extraordinary circumstances.
• Damages / out-of-pocket costs. Reasonable expenses caused by the disruption are a separate claim in their own right.

Watch one trap on the numbers. Under Art. 7(2), Wizz may lawfully reduce compensation by 50% (so EUR 600 becomes EUR 300) if it re-routed you to arrive within a set window. EUR 300 or EUR 500 is never a standalone statutory amount — only ever the reduced figure. If Wizz offers a "goodwill" sum below your full entitlement, you can accept it on account and still pursue the balance. To confirm the correct figure, use our flight compensation calculator.

Escalating after a second refusal

If Wizz maintains its rejection or ignores your deadline, you have several routes and you do not have to choose only one over time:

• The national enforcement body (NEB) or the UK CAA. For UK departures, complain to the Civil Aviation Authority. For EU/EEA departures, complain to the NEB of the country you departed from. As background, the CAA took enforcement action in 2023, when Wizz Air gave undertakings to improve how it pays refunds and EU261 claims and to clear its backlog — useful context if payment is being delayed.
• Alternative dispute resolution (ADR). In the UK, Wizz's approved ADR body can issue a binding decision on your claim, usually for free to you.
• Court. A small-claims or equivalent procedure is often the most reliable route for a clear-cut delay. Time limits to sue vary: roughly 6 years in England and Wales and in Ireland, 5 years in Scotland, and differing periods across EU states, so check your own jurisdiction rather than assuming a single deadline.

For the wider picture, start from the Wizz Air flight compensation hub, and read the specific guides on a delayed flight or a cancelled flight.

A separate note on baggage

Lost, damaged or delayed bags are governed by the Montreal Convention, not EU261/UK261. Liability is capped at about 1,519 SDR per passenger (the ceiling in force since 28 December 2024, roughly EUR 1,850 / GBP 1,600 and moving with exchange rates). File a Property Irregularity Report at the airport, then write to Wizz within 7 days for damage or 21 days for delay. That is a separate claim and never the 250/400/600 or 220/350/520 figure.

FAQ — Frequently asked questions

Can Wizz refuse just by saying "operational reasons"?

No. That phrase is not a defence in itself. Wizz must identify the actual cause and, if it claims extraordinary circumstances, prove them.

They blamed a technical fault — is that extraordinary?

Usually not. A routine technical or mechanical fault is part of normal operations and does not remove compensation (Wallentin-Hermann; van der Lans).

What if the delay was a Wizz crew strike?

A strike by the airline's own crew is not extraordinary, and compensation remains payable (Airhelp v SAS, C-28/20).

Do I lose care and refund rights if compensation is refused?

No. Refund/re-routing (Art. 8) and care (Art. 9) are separate and still apply, and care is due even in extraordinary circumstances.

Should I mention the 2026 EU261 reform?

Only as background. The proposed longer delay thresholds, a nine-month claim window and a 30-day airline response deadline are a proposal, not yet law. Claim on the rules in force today.
