EU Regulation 261/2004 is the single most powerful passenger rights law in the world, and it entitles you to fixed cash compensation of €250, €400 or €600 when your flight is cancelled, delayed by three hours or more at arrival, or when you are denied boarding due to overbooking. Knowing how to claim EU flight compensation under Regulation 261/2004 is worth real money: airlines pay out billions in compensation each year, yet industry estimates suggest fewer than 15% of eligible passengers ever file a claim, largely because the process feels intimidating or airlines reject valid claims in the hope that passengers give up. This guide walks you through exactly who qualifies, how much you are owed, the step-by-step claim process, the excuses airlines use, and what to do when they refuse to pay.

Regulation 261/2004 applies to any flight departing from an airport located in the European Union, regardless of the airline's nationality. That means a delayed American Airlines flight from Paris to New York is fully covered, even though the airline is American. It also covers flights arriving in the EU when operated by an EU-registered carrier, so a Lufthansa flight from Chicago to Frankfurt is covered, but a Delta flight on the same route is not. The regulation also extends to Iceland, Norway and Switzerland, and, following Brexit, the UK retained equivalent rules under UK261 for flights departing UK airports and arriving on UK or EU carriers.

The passenger must have a confirmed reservation, checked in on time (unless the delay was not communicated to you in advance), and must not have accepted a voucher or travel credit in settlement. Airlines sometimes offer vouchers at the gate during disruptions; accepting one usually waives your right to the cash compensation, so read anything you sign carefully. Compensation is per passenger, including children with paid tickets, so a family of four on a long-haul delay can be owed €2,400 or more.

## What You Can Claim: The Compensation Amounts

The amounts are fixed by distance, not by what the ticket cost you. A €40 budget fare earns exactly the same compensation as a €2,000 business fare on the same delayed route. The tiers are: €250 for flights up to 1,500 km; €400 for intra-EU flights over 1,500 km and all other flights between 1,500 km and 3,500 km; and €600 for all flights over 3,500 km (and €400 for intra-EU flights over 3,500 km that are not covered by the higher band).

For delays, the delay is measured at arrival at your final destination, not at departure. A flight that leaves two hours late but arrives under three hours late generally earns nothing. There is one important reduction rule: if you are re-routed on a comparable flight and arrive within two hours of your original arrival time (1,500 km or less), three hours (1,500–3,500 km), or four hours (over 3,500 km), the airline can cut the compensation by 50%. Beyond compensation, the airline must also provide meals, refreshments, hotel accommodation and transfers during long waits, and if a cancellation or long delay ruins your holiday plans, you can additionally claim consequential losses like rebooked hotels or missed tours under the Montreal Convention, though these require receipts.

| Disruption | Distance | Compensation | Minimum delay at arrival |
| --- | --- | --- | --- |
| Delay or cancellation | Up to 1,500 km | €250 | 3 hours |
| Delay or cancellation | 1,500–3,500 km | €400 | 3 hours |
| Delay or cancellation | Over 3,500 km | €600 | 3–4 hours |
| Denied boarding (any reason except your fault) | Any distance | €250–€600 | Immediate |
| Downgrading | Any distance | 30–75% of ticket price refund | Immediate |

## The 'Extraordinary Circumstances' Defence
Airlines avoid paying in roughly half of disputed cases by invoking extraordinary circumstances, and this is where most claims are won or lost. Extraordinary circumstances are events outside the airline's control that could not have been avoided even if all reasonable measures were taken. Accepted examples include genuine severe weather, air traffic control strikes by third parties (not airline staff), security threats, and bird strikes causing hidden damage. The Court of Justice of the EU has repeatedly narrowed the defence: technical faults discovered during routine maintenance, crew shortages, and airline staff strikes are NOT extraordinary circumstances, because they stem from the airline's own operations.

Recent years have tested the boundaries further. When Lufthansa ground staff strikes grounded flights across German hubs, courts treated those as the airline's problem, not yours, and compensation remained payable. Airlines also increasingly cite hidden manufacturing defects, such as the Pratt & Whitney engine issues affecting Airbus A320neo family aircraft, as extraordinary; regulators in several countries have pushed back, noting that ordering standby aircraft or rebooking passengers on other carriers counts as a 'reasonable measure' the airline should have taken. If an airline claims extraordinary circumstances, you are entitled to ask for written evidence, and many rejections collapse when challenged. This is precisely why claims handled by specialists, including AI-assisted services like AI Flight Refunds that cross-reference court rulings and historical flight data, succeed far more often than first-attempt letters.

## Step-by-Step: How to File Your Claim

Start by gathering your evidence before writing anything. You will need your booking confirmation, boarding pass (or proof of check-in), and the actual arrival time of your flight, which you can verify through independent flight-tracking data rather than the airline's own figures. Take screenshots of any delay announcements at the airport, and keep receipts for meals, hotels and taxis, since the duty-of-care expenses are claimable on top of the fixed compensation and airlines must reimburse reasonable costs.

Next, identify the correct airline to sue: file with the operating carrier, not the airline that sold you the ticket. If you booked through an online travel agency, the airline may redirect you, but under EU261 the operating carrier remains liable for the compensation. Submit your claim in writing, ideally by email so you have a timestamped record, and state explicitly that you are claiming under Regulation (EC) No 261/2004, specify the flight number, date, route, delay at arrival, and the exact amount you claim. Include your bank details for the transfer and a deadline, commonly 14 to 30 days. Keep it factual and unemotional; compensation officers process thousands of claims and respond better to precise legal language than to complaints about ruined holidays.

If the airline pays, expect the money within weeks. If it ignores you or rejects the claim, move to escalation, which is where most compensation is actually recovered. A well-documented first letter with the correct legal framing succeeds far more often than a vague complaint, and services that automate this drafting, such as AI Flight Refunds, exist precisely because the wording matters.

## Deadlines: How Long You Have to Claim

EU261 itself sets no deadline; the limitation period is defined by each member state's national law, and the range is wide. In the UK and Ireland it is six years, in Spain five years, in France and Germany (for contractual claims) around three years, in Belgium one year, and in Italy two years. Denmark applies just two years. This asymmetry catches travellers out constantly: someone flying through Brussels may believe their one-year-old claim has expired when it would still be very much alive if filed against the same carrier from another jurisdiction. As a practical rule, file as soon as possible, but do not assume an old claim is dead until you have checked the specific limitation period for your departure country.

The date of disruption matters too. For a claim arising today, 15 September 2026, you would typically have until at least 2029 and possibly until 2032 depending on jurisdiction. Airlines occasionally argue for shorter deadlines than national law actually provides; if you receive such a rejection, verify the statute of limitations independently before accepting it.

## Escalation Options When the Airline Refuses

Every EU member state (and the UK) has a National Enforcement Body (NEB) responsible for supervising EU261 compliance, such as the CAA in the UK, the IAA Commission for Aviation Regulation in Ireland, or the LBA in Germany. Filing a complaint with the NEB is free and can pressure an airline into paying, though enforcement quality varies dramatically between countries; some NEBs investigate thoroughly while others merely forward your complaint to the airline and close the file. NEB involvement does not by itself guarantee payment, so treat it as one lever among several rather than a complete solution.

If the NEB route stalls, the courts are your strongest option. Small claims courts handle EU261 cases routinely, filing fees are typically modest (often under £50–€100), and legal expenses insurance included in many home or credit card policies may cover the costs. Crucially, the Court of Justice of the EU has confirmed that passengers can sue in the courts of their arrival airport as well as departure, which is useful when the airline's home country is unhelpful. For travellers who do not want to litigate, claims companies and AI-driven services like AI Flight Refunds handle the entire process, including court escalation where permitted, in exchange for a commission, typically 25–35% of the payout and usually nothing if the claim fails. Paying a third to recover €600 is not ideal, but it beats the €0 many self-represented passengers walk away with after a rejection letter.

| Route | Cost | Typical timeframe | Success rate |
| --- | --- | --- | --- |
| Direct claim to airline | Free | 2 weeks–3 months | Moderate; often rejected first |
| National Enforcement Body | Free | 2–6 months | Low to moderate, varies by country |
| Small claims court | €30–£250 fees | 3–12 months | High with good evidence |
| Claims company / AI service | 25–35% commission | 1–6 months | High; specialists know the tactics |

## Common Mistakes That Kill Valid Claims
The most damaging mistake is accepting a voucher or signing a settlement at the airport, which airlines often present as the only immediate option during chaos. Another frequent error is claiming based on departure delay rather than arrival delay; a flight delayed two hours on departure that arrives on time owes you nothing under EU261, though duty-of-care expenses may still apply. Passengers also routinely underclaim by forgetting that compensation is per passenger and forgetting separate Montreal Convention claims for consequential losses like a prepaid hotel night or a missed cruise connection, which can exceed the EU261 amount itself.

Documentation failures sink many otherwise valid cases. Without your boarding pass, the airline may dispute you were on the flight; without independent arrival-time data, the airline may downplay the delay. Accepting the airline's first rejection at face value is perhaps the most expensive mistake of all, because many rejections are boilerplate citing 'extraordinary circumstances' without any evidence, and a significant share are reversed on appeal or when challenged with case law such as the landmark Sturgeon and TAP Portugal rulings that established delay compensation. Finally, some passengers book connecting flights on separate tickets to save money, not realising that a missed connection on a separate ticket may fall outside EU261's protections unless both legs were on a single booking.

## Upcoming Reforms and Why You Should Act Now

The EU has been debating a revision of Regulation 261/2024-era rules, with Council proposals circulated in 2025 suggesting thresholds for delay compensation be raised to four hours for short flights, potentially linked to flight distance in new ways, and stronger obligations on airlines regarding rebooking and refunds. Industry pressure has pushed to weaken compensation, while consumer groups resist. Nothing is enacted as of September 2026, but the direction of travel suggests future entitlements may be harder to secure. Waiting for reform is a poor strategy; claims are assessed under the law in force on the date of your flight, so a disruption in 2026 will be judged under the current, passenger-friendlier regime regardless of what happens later.

Practical timing advice: file within days of the disruption while evidence is fresh and airline records are accurate, keep every receipt, and if you receive a rejection, escalate within the statutory deadline rather than letting the file go cold. Whether you pursue the airline yourself, through an NEB, via the courts, or with an AI-assisted claims service, the money is legally yours, the amounts are fixed and substantial, and the single biggest determinant of success is simply refusing to stop after the first 'no'.

## Bottom Line

Regulation 261/2004 pays €250 to €600 per passenger in fixed cash compensation for cancellations, three-hour-plus arrival delays and denied boarding, on top of meals, hotels and consequential losses. The process is a letter, patience, and escalation, and the main obstacles are airline stonewalling and the extraordinary-circumstances defence, both of which are beatable with evidence and correct legal framing. Check your eligibility now, because limitation periods, while generous in some countries, run out quietly.

## Quick answers

### How much compensation can I get under EU261?

Fixed amounts of €250 for flights up to 1,500 km, €400 for 1,500–3,500 km, and €600 for flights over 3,500 km, per passenger. Delays must reach three hours or more at final arrival, and the airline can reduce the amount by 50% if you are rebooked and arrive within two, three or four hours depending on distance.

### What counts as extraordinary circumstances under EU261?

Genuine severe weather, third-party air traffic control strikes, security risks and unforeseeable events qualify. Technical faults found in routine maintenance, crew shortages, and airline staff strikes do not, per repeated EU Court of Justice rulings. Airlines must provide written evidence if they invoke the defence.

### How long do I have to file an EU261 claim?

The deadline depends on national law of the departure country: six years in the UK and Ireland, five in Spain, three in Germany and France, two in Italy and Denmark, and only one in Belgium. File as early as possible to preserve evidence.

### Do I need a claims company to get EU261 compensation?

No. You can claim directly for free, escalate to a National Enforcement Body, or use small claims court. Claims companies and AI-assisted services charge roughly 25–35% commission but handle rejections and legal escalation, which increases success rates for contested claims.

### Does EU261 apply to flights from the EU to the USA?

Yes, EU261 covers all flights departing from EU airports regardless of airline nationality, so a delayed or cancelled flight from Paris to New York on any carrier is eligible. Flights into the EU are only covered when the airline is EU-licensed.
