EU261 Explained: How to Claim the Flight Compensation You’re Legally Owed

Every year, millions of passengers across Europe experience flight delays and cancellations. Most of them never see a cent in compensation — not because they aren’t entitled to it, but because they don’t know the rules. EU Regulation 261/2004 is one of the strongest pieces of consumer protection legislation in the world, yet the vast majority of eligible travellers never file a claim.

This is your guide to understanding what you’re owed and how to get it.

What Is EU261?

EU261 is a regulation passed by the European Parliament in 2004 that sets out the rights of air passengers when their flights are delayed, cancelled, or overbooked. It applies to an enormous range of journeys — far more than most travellers realise — and entitles qualifying passengers to financial compensation, duty of care, and in some cases a full refund or rerouting.

The regulation was a direct response to airlines routinely leaving passengers stranded without explanation or redress. Before it came into force, your options when a flight went wrong were limited and largely dependent on the goodwill of the carrier. EU261 changed that by creating legally enforceable rights with fixed compensation amounts.

Which Flights Are Covered?

Coverage under EU261 depends on two factors: where the flight departs from, and which airline is operating it.

You’re covered if your flight departs from any airport within the European Union, regardless of the airline. You’re also covered if your flight arrives into the EU and is operated by a European carrier — even if it departs from outside Europe. UK routes are also still covered under the retained version of the regulation following Brexit.

This means a wide net of journeys qualify, including many long-haul and transatlantic routes.

When Does Compensation Apply?

For delays specifically, compensation kicks in when you arrive at your final destination three or more hours late. The key word is “arrive” — this is measured by when the aircraft doors open at the destination, not when wheels touch the runway.

The delay must also be caused by something within the airline’s control. Extraordinary circumstances — genuine severe weather, air traffic control decisions, political instability — are exempt. However, technical faults are generally not considered extraordinary circumstances, even when airlines try to argue otherwise. Courts have consistently upheld that routine maintenance failures and mechanical issues are part of normal airline operations.

The Compensation Amounts

EU261 sets fixed, non-negotiable amounts based on the distance of the route:

• Flights up to 1,500 km: €250 per passenger
• Flights between 1,500 km and 3,500 km: €400 per passenger
• Flights over 3,500 km: €600 per passenger

These figures apply per person, per disrupted flight. A couple on a long-haul route delayed by four hours could claim €1,200 between them. There’s no means testing, no cap based on ticket price, and no requirement to prove financial loss. The entitlement exists purely on the basis of the disruption.

Right to Care

Alongside financial compensation, airlines have an obligation to look after passengers during significant delays. From two hours onwards, you’re entitled to meals and refreshments appropriate to the waiting time. If the delay extends overnight, the airline must provide hotel accommodation and transport between the airport and hotel at no cost to you.

This duty of care applies regardless of whether you’re ultimately entitled to financial compensation. Even if the delay turns out to be caused by extraordinary circumstances, the airline still has to feed you and, if necessary, put you up for the night.

If an airline fails to provide this and you cover the costs yourself, keep every receipt. You can submit these for reimbursement alongside or separately from your compensation claim.

How to File a Claim

Start by contacting the airline directly. Most have a dedicated claims or customer relations department, and many now have online submission forms. Provide your booking reference, flight number, departure and arrival times, and a brief description of the disruption.

Airlines are required to respond, but response times vary wildly and initial rejections are common. If your claim is denied, you can escalate to your country’s national enforcement body — in the UK that’s the Civil Aviation Authority, in Germany the Luftfahrt-Bundesamt, and so on across Europe.

Alternatively, claims management services exist specifically to take this burden off passengers. Voos is one such service — they assess your eligibility for free, handle all communication with the airline, and only charge a fee if your claim is successful. For passengers specifically pursuing a KLM compensation claim, they manage the full process from submission through to payment.

Common Reasons Claims Get Rejected

Airlines use several standard arguments to push back on claims. The most common is invoking extraordinary circumstances — citing weather or technical issues as outside their control. Many of these rejections don’t hold up under scrutiny, particularly technical fault claims, but passengers who don’t challenge them simply walk away empty-handed.

Other common tactics include offering vouchers instead of cash, citing incorrect time calculations, or simply hoping passengers give up after one rejection. Knowing this in advance puts you in a stronger position.

Documentation to Keep

You don’t need a thick folder of evidence to make a claim, but a few things help. Your booking confirmation and boarding pass are the basics. A screenshot of the departures board showing the delay is useful. Note the time the aircraft doors opened at your destination if you can — that’s the legally relevant arrival moment.

If you were given any written communication from the airline at the airport explaining the cause of the delay, hold onto that too.

The Time Limit

Claims have a statute of limitations that varies by country — typically two to six years from the date of travel. While this gives you some breathing room, older claims are harder to process. Booking references expire from airline systems, documentation gets lost, and memories fade. If you think you have a valid claim, sooner is always better than later.

Why Most People Don’t Claim

Research consistently shows that only a small fraction of eligible passengers ever file a claim under EU261. The reasons are predictable: people don’t know the regulation exists, assume the process is too complicated, or give up after a single rejection. Airlines are well aware of this, and their claims processes are rarely designed to make things easy.

The regulation was written to give passengers real power over airlines. Using it is simply a matter of knowing it’s there.
