The Short Answer to EU261 Filing Deadlines

There is no single EU-wide deadline for filing an EC261 flight-compensation claim. EC261 itself, now formally known as Regulation (EC) No 261/2004, requires passengers to report the problem to the airline “within a reasonable period,” but it does not define a fixed number of days or years. The practical deadline therefore depends mainly on the country where the affected flight departed, because national limitation rules fill the gap. As of 29 September 2026, a passenger should not wait six years or assume that an airline can ignore an old claim.

A sensible filing target is within 30 to 90 days of the disrupted flight, while passengers returning to the United Kingdom should normally claim within six years. Deadlines of roughly one, three, or six years can apply elsewhere, but some countries distinguish contractual claims from statutory passenger-rights claims, and courts may apply concepts such as knowledge, concealment, or reasonable time. The sooner a claim is filed, the easier it usually is to obtain the booking record, establish the route, document expenses, and identify the party responsible for the flight.

## What EC261 Covers

EC261 compensation generally applies when an airline is responsible for a flight departing from the EU, or when the flight is an EU carrier arriving outside the EU. The principal compensation grounds are a cancellation, a delay of at least three hours in reaching the final destination, or a rerouting that adds specified amounts of time to the original journey. A missed connection can also qualify, particularly where it was sold as part of a single booking or under protected onward arrangements. Simply missing a separately booked self-transfer flight does not automatically make the first airline liable.

The compensation bands are €250, €400, and €600 per passenger, depending on the route distance and disruption type. For example, a qualifying cancelled flight of 1,500 kilometres or less may attract €250, while a qualifying cancellation on a flight exceeding 6,000 kilometres may attract €600. The amount is not a refund of the ticket price. Care, meals, accommodation, transport, and other necessary expenses may be recoverable separately, although passengers may need to show that reasonable costs were incurred and that the airline did not provide them.

EC261 is also narrower than many passengers expect. It applies principally to flights, not a long list of every travel problem, and eligibility can be affected by extraordinary circumstances. Weather, security events, air-traffic-control restrictions, and certain political or pre-flight decisions can remove a right to operational compensation even where the disruption was commercially inconvenient. For that reason, a claim should establish both the disruption and the precise reason the airline says it occurred.

Why There Is No Single EU Deadline

The lack of a uniform EU deadline does not mean that a passenger has an unlimited time to approach a court. EU member states retain their own rules on limitation periods for civil claims, and those rules may have been changed or are being reconsidered. A claim under the Montreal Convention can have a different route and period from a national action based directly on EC261. Which legal theory is being used can matter, especially near the end of a limitation period.

Airlines frequently state that complaints must be made within one year. That may reflect an internal customer-service standard rather than the full period available in a national court, but it can still create a practical obstacle if the airline rejects a complaint as late. It is therefore safer to contact the airline promptly and also consider a small-claims procedure before the relevant national deadline. Waiting for a new route or a rebooked flight can also make it harder to demonstrate the disruption that occurred on the original journey.

National enforcement bodies may take complaints even when a court would later question whether the claim is time-barred, but that is not a guarantee. Neither should a passenger assume that lodging a complaint online automatically stops a limitation clock in every country. A robust filing includes a dated written claim, a delivery method that can be proved, a clear description of the journey, and an explicit request for the EC261 remedy sought.

How to File a Claim Within the Deadline

Start with the airline named on the booking, and send a concise written claim within days or weeks rather than waiting for the full statutory period. Include the passenger's full name, booking reference, flight number, operating airline, original and actual destinations, disruption date, scheduled arrival time, and reason for the claim. Attach the ticket confirmation, itinerary, airline disruption notice, and relevant messages. Keep copies of the sent email, postal receipt, online claim form, call notes, and every subsequent response.

A claim should ask clearly for EC261 compensation, not merely a refund or voucher. The total requested should calculate the relevant €250, €400, or €600 band for every eligible passenger. It can also request reimbursement for documented refreshments, hotel, transport, and care expenses, subject to the airline's compliance with EC261's separate duty of assistance. If the airline pays a ticket refund but denies EC261 compensation, the passenger should ask for a separate written explanation of the denial.

## Which National Deadline May Apply

Because the date in this answer is 29 September 2026, a passenger should verify the current rule for the country of departure rather than relying on an old table published before national reforms. In England and Wales, passengers and consumer advisers commonly identify a six-year contractual limitation period for an EC261-related claim. In Germany, a three-year limitation period has commonly been cited for relevant claims, although changes proposed under consumer-protection reform may affect how some claims are treated. France has often been described as allowing five years for consumer claims, while the Netherlands has also been associated with a three-year framework.

These figures are not a substitute for legal advice and do not cover every legal route. Some jurisdictions distinguish claims brought by a passenger from claims brought by a representative or an organization, while others treat air carriage through specific national legislation. Montreal Convention Article 29 is a further consideration because treaty-based claims have their own conditions and generally use the law of the country where the carrier has its principal place of business. A passenger with a borderline deadline should obtain advice from the relevant national body or a qualified lawyer before taking no action.

A useful way to think about the deadlines is to use three dates: the date of the flight, the date written notice reaches the airline, and the date that the user asks a national body or court to decide. The first determines the disruption; the second demonstrates that the complaint was made within a reasonable period; the third is most likely to be tested against national limitation rules. Filing early addresses all three concerns and gives the passenger room to deal with an airline's delay or rejection.

Compensation, Refunds, and Other Remedies Compared

Passengers often confuse EC261 compensation with a ticket refund, a delayed-flight payment, or the cost of getting home. These remedies can overlap, but they answer different questions. A refund may return the unused fare in a cancellation or certain rerouting circumstances, whereas EC261 compensation is a fixed sum based on distance and disruption. If an airline rebooks the passenger and gets them to the final destination within the permitted time, that does not necessarily prevent a refund claim in every circumstance, nor does accepting a rerouting automatically waive compensation.

Other routes include the airline's complaint process, the national civil-aviation or consumer body, small-claims court, an approved dispute-resolution service, or legal proceedings. Court fees vary widely, and a national body may accept a complaint without charging a filing fee, while lawyers, expert reports, and travel can make litigation expensive. No claim service can guarantee recovery because facts, national law, and defenses differ. A claim-management company may offer a contingency arrangement, but the passenger should understand any success fee, deadline waiver, administration cost, and treatment of existing airline payments before signing.

Common Mistakes That Can Defeat or Delay a Claim

The most damaging mistake is relying on an airline's one-year customer-service statement while waiting several years to approach a court. Another common error is claiming only from the booking airline even though the operating airline handled the disrupted segment. Airline and operating carrier can differ, and the claim may still be brought against the relevant party, but accurate identification avoids unnecessary transfers. Passengers also frequently use the wrong delay measure by looking at departure rather than arrival; EC261 generally considers arrival at the final destination.

A cancellation, a denied boarding, a long delay, and a missed connection are not interchangeable. Filing a vague “flight problem” may not establish that the journey met a statutory threshold. Passengers also fail to keep receipts, fail to state the number of affected travelers, or do not distinguish the scheduled destination from the connecting city. A separate self-transfer arranged at low cost may fall outside EC261 even when the passenger strongly believes the airline caused the missed connection.

Finally, extraordinary circumstances are often overstated or overlooked. A technical defect on the airline's own aircraft is generally not extraordinary, while a severe weather event or ATC disruption may be. A post-dispute decision by a court or an update in national law can affect an old claim, so sources published in 2019 or earlier should be treated as background rather than current deadline authority. A professional review is more reliable when the route, disruption, date, and departure country are known.

When to Act and How to Keep the Filing Cost Down

Act quickly if the flight has just been cancelled, delayed by three hours or more, or rerouted. There is little advantage to waiting because the strongest evidence is freshest, the airline can be located while the case is active, and an airline's refusal can be challenged before memories fade. Within the first few days, save the disruption notification, boarding passes, booking emails, and receipts. Within 30 days, submit a clear claim. If an answer has not arrived after several weeks or the airline denies the claim, preserve the complete file and check the national enforcement route.

The direct claim can usually be made without buying software or paying a court fee. Use the airline's published email or form where possible, send one coherent message, and keep the original attachments. Legal fees, claim-management fees, expert analysis, and court costs depend on the route. A lawyer can help where the departure country is uncertain, the disruption involved a protected connecting itinerary, the amount is high, or a limitation deadline is close. For a single short-distance passenger, direct airline escalation or a no-fee national complaint channel may be proportionate, but that is a practical judgment rather than a guarantee of success.

No one should delay action because a site advertises “free compensation.” A free assessment may be useful, but the user still owns the claim, supplies the evidence, and remains responsible for verifying the filing deadline. The best assistance reduces paperwork and explains eligibility, but it cannot change the legal period or guarantee an award. The safest approach is prompt notice, documented delivery, accurate legal framing, and professional advice only where the dispute is complex or the deadline is genuinely near.
