Flight delay compensation — complete guide

Flight delays are one of the most common travel disruptions in Europe. Millions of passengers experience them every year — yet the vast majority never claim the compensation they are legally entitled to. If your flight arrived at its destination more than three hours late, you may have a right to receive between €250 and €600 per person under European Union law. Here is everything you need to know.

What Is Flight Delay Compensation?

Flight delay compensation is a fixed payment that airlines are required to make to passengers whose flights arrive significantly late. The right to this compensation is established by European Parliament and Council Regulation EC 261/2004, which has been in force since February 2005.

The regulation applies to all flights departing from an EU airport, regardless of which airline operates them. It also applies to flights arriving at an EU airport, but only if the operating carrier is registered in the European Union. This means that if you fly from Warsaw to New York with LOT Polish Airlines, you are covered. If you fly from New York to Warsaw with a US carrier, you are not — unless you departed from an EU country at any point in your journey.

The regulation covers three main situations: significant flight delays, flight cancellations, and denied boarding due to overbooking. Each entitles the passenger to a fixed cash payment, regardless of the ticket price paid.

When Does the Right to Compensation Apply?

Not every delay gives rise to a compensation claim. The key threshold under EC 261/2004 is an arrival delay of three hours or more at the final destination. It is the arrival time that matters — not the departure time. If your flight pushed back from the gate an hour late but made up time in the air and landed only two hours and fifty minutes after the scheduled arrival, you are not entitled to compensation under this rule.

The three-hour threshold was established not by the original text of the regulation, but by a landmark ruling of the Court of Justice of the European Union in the Sturgeon v Condor case in 2009. The court held that passengers on significantly delayed flights should be treated the same as those on cancelled flights for the purposes of compensation — a decision that dramatically expanded passenger rights across Europe.

There is one important exception. Airlines are not required to pay compensation if the delay was caused by extraordinary circumstances that could not have been avoided even if all reasonable measures had been taken. The most commonly cited examples include severe weather conditions, air traffic control restrictions, political instability, and security threats. However, airlines frequently attempt to use this exemption more broadly than the law allows — citing technical faults, crew shortages, or knock-on delays from earlier flights as extraordinary circumstances, which they are generally not.

How Much Compensation Can You Claim?

The amount of flight delay compensation you are entitled to depends on the distance of the flight, not on the price of your ticket or the class you travelled in:

€250 — for all flights of 1,500 kilometres or less. This covers most short-haul routes within Europe, such as Warsaw to Vienna, London to Amsterdam, or Paris to Madrid.

€400 — for all intra-EU flights of more than 1,500 kilometres, and for all other flights between 1,500 and 3,500 kilometres. This applies to routes such as Warsaw to London, Madrid to Istanbul, or Rome to Cairo.

€600 — for all flights of more than 3,500 kilometres that are not intra-EU flights. This covers long-haul routes such as London to New York, Frankfurt to Tokyo, or Amsterdam to São Paulo.

In some cases, the airline may offer an alternative form of compensation — such as vouchers, upgrades, or rebooking on a later flight. You are not obliged to accept these alternatives instead of cash. If you accept a voucher under pressure without being clearly informed of your right to monetary compensation, you may still have grounds to claim.

It is also worth noting that these amounts apply per passenger. A family of four on a transatlantic flight that arrives more than three hours late could theoretically be entitled to €2,400 in total — €600 for each person, including children who had their own ticket.

What About Flight Cancellations and Overbooking?

While this article focuses on delays, it is worth briefly noting that the same regulation covers two other common disruptions.

If your flight is cancelled and you were not informed at least 14 days before the scheduled departure, you are entitled to the same fixed compensation amounts as for delays — €250, €400, or €600 depending on the distance. You are also entitled to a choice between a full refund of your ticket price or rebooking on an alternative flight to your destination at no extra cost.

If you are denied boarding against your will because the airline has sold more seats than are available on the aircraft — a practice known as overbooking — the same compensation rules apply. Airlines are required to ask for volunteers willing to give up their seats before involuntarily denying boarding to any passenger. Volunteers are typically offered incentives negotiated at the gate, which may include travel vouchers, cash, or upgrade to a later flight in a higher class.

How Far Back Can You Claim?

One of the most common misconceptions about flight compensation is that you can only claim for recent disruptions. In reality, the statute of limitations varies by country and can be considerably longer than most passengers assume.

In the United Kingdom, passengers can claim for flights going back up to six years under the Limitation Act 1980. In Germany, the standard limitation period is three years from the end of the calendar year in which the disruption occurred. In France, it is five years. In Poland, the general limitation period for such claims is one year from the date of the flight, though this can be extended in certain circumstances.

This means that if your flight was significantly delayed two or three years ago and you never claimed, it may not be too late. It is worth checking your travel records and email confirmations from past trips, particularly for long-haul flights where the potential compensation is €600 per person.

How to Make a Claim

There are three main routes to claiming flight delay compensation: directly with the airline, through a national enforcement body, or through a specialist claims service.

Claiming directly with the airline is the simplest starting point but often the least effective. Most major carriers have online claim forms, and some will pay out quickly when the case is straightforward. However, airlines routinely reject valid claims by citing extraordinary circumstances, using vague or misleading language, or simply hoping passengers will give up. If the airline rejects your claim or does not respond within eight weeks, you have the right to escalate.

National enforcement bodies are the regulatory authorities responsible for enforcing EC 261/2004 in each EU member state. In Poland, this is the Office of Civil Aviation (Urząd Lotnictwa Cywilnego). In Germany, it is the Luftfahrt-Bundesamt. In the UK, it is the Civil Aviation Authority. These bodies can investigate complaints and order airlines to pay, but they are often slow and cannot always compel payment directly.

Specialist claims services handle the entire process on your behalf — from initial assessment through correspondence with the airline to legal action if necessary. The best services operate on a no win, no fee basis, meaning you pay nothing unless your claim is successful. If you use ClaimWinger, the commission is charged only on the amount actually recovered, so there is no financial risk to you at any stage of the process.

What Documents Do You Need?

You do not need an extensive paper trail to make a successful claim, but having the right information makes the process significantly faster.

The most important details are your booking reference or e-ticket number, the flight number, the scheduled and actual departure and arrival times, and the name of the operating airline. If you received any communication from the airline about the delay — whether by SMS, email, or notification through an app — keep a copy of this. If you were given meal vouchers or accommodation at the airport, keep those receipts too, as they can support your account of events.

You do not need the original boarding pass in most cases, although it can help confirm that you actually boarded the flight. In the absence of a boarding pass, a booking confirmation and bank statement showing the ticket purchase is usually sufficient.

Common Reasons Airlines Reject Claims — and Why They Are Often Wrong

Understanding the most frequent rejection arguments helps you challenge them effectively.

“The delay was caused by extraordinary circumstances.” This is by far the most common rejection reason. However, airlines regularly apply this label to situations that do not legally qualify. A technical fault discovered during pre-flight checks is generally not an extraordinary circumstance — it is an inherent part of airline operations. A crew member exceeding their maximum working hours due to poor scheduling is not extraordinary either. Only genuinely unforeseeable external events, such as a sudden volcanic ash cloud or an unexpected security alert, are likely to succeed as a defence.

“You checked in late.” If you checked in after the deadline and missed the flight as a result, the airline is not liable. However, if the delay occurred after you had already boarded or checked in on time, late check-in is irrelevant.

“You accepted a voucher.” Accepting a voucher at the airport does not automatically waive your right to monetary compensation, particularly if you were not clearly informed in writing of your right to choose cash instead. If you signed anything, the situation becomes more complex and may require legal advice.

“The claim is out of time.” Airlines sometimes incorrectly apply a shorter limitation period than the one applicable in your jurisdiction. If you are unsure whether your claim is time-barred, a specialist service can assess this for you at no cost.

Why Most Passengers Never Claim

Research consistently shows that the majority of passengers who are entitled to flight delay compensation under EC 261/2004 never make a claim. The reasons vary: some are unaware the right exists, others assume the process is too complicated, and many give up after receiving an initial rejection from the airline.

The result is that airlines collectively save hundreds of millions of euros every year that they are legally required to pay out. The passengers who do claim — particularly those who use specialist services rather than pursuing airlines alone — recover compensation at a significantly higher rate than those who do not.

If your flight was delayed by more than three hours in the past few years, the most important first step is simply to check whether you have a valid claim. In most cases, this takes a few minutes and costs nothing.
