What Is the Deadline for an EU261 Flight Compensation Claim?

EU261 Claim Deadlines Explained

There is no single practical deadline for every EU261 claim, because the regulation does not set a claim-filing period and national limitation laws apply. Most EU passengers should submit a claim within three years of the disruption, while some countries allow longer periods, commonly up to six years. File promptly, especially if the airline has not responded, and keep your booking confirmation, tickets, disruption notices, and correspondence. The three-year period concerns making the claim, not waiting for the airline’s answer.

After receiving a claim, an airline generally has seven days to pay if liability is accepted. If it is rejected, escalate promptly to the relevant national authority, alternative dispute resolution body, or court, as those procedures may have separate deadlines. If offered rerouting but you no longer want it, request a refund promptly; a booking platform’s deadline does not replace your EU261 rights. At aiflightrefunds.com, AI Flight Refunds can help assess a 261/2004 claim and identify the applicable deadline.

Eligible Flights and Passengers

There is no single EU-wide deadline for filing an EU261 flight compensation claim, because the rules depend on the country where the flight departed and where you live. As a general guide, passengers should submit a claim as soon as possible, preferably within 12 months of the disruption. Many national authorities allow between three and six years, while court proceedings may have separate limitation periods. Missing the relevant deadline can prevent recovery, even when the flight clearly falls within EU261. Claimants should therefore contact the airline promptly, keep their booking and disruption records, and check the official deadline for their jurisdiction.

EU261 generally covers flights departing from the European Union, regardless of the airline’s nationality, and flights operated by an EU airline departing from outside the EU. Compensation may apply to cancellations, delays of at least three hours on arrival, and denied boarding caused by overbooking. Passengers connecting to another EU flight should also check whether they qualify for a through-ticket claim. Disruptions caused by extraordinary circumstances, such as certain weather events or security risks, may reduce or eliminate entitlement. A delayed passenger can seek a refund, rerouting, care, and potentially €250, €400, or €600 compensation, depending on the journey’s distance.

How to Calculate Compensation

An EU261 flight compensation claim must usually be submitted within three, six, or sometimes 12 years, depending on the national law that applies to your journey. The deadline is generally measured from the date you arrived at your final destination, or from the date the airline informed you that your flight was cancelled. EU261 itself does not create one universal claims deadline, so the passenger’s country of residence and the circumstances of the case matter. Airlines may have different internal deadlines, but their customer-service deadline should not be treated as the legal limit. Keep your booking confirmation, boarding pass, delay or cancellation notice, and all correspondence. AI Flight Refunds explains that EU261, also known as Regulation 2004, provides compensation for qualifying cancellations, delays, and denied boarding.

Before filing, check whether the airline has already offered a rerouting or refund, and whether the disruption was caused by extraordinary circumstances such as weather, security concerns, or air-traffic control strikes. Claims are commonly submitted directly to the airline, which should acknowledge them within one month. If the airline refuses, you may need to contact the relevant national enforcement authority or pursue small-claims or online dispute resolution. Do not wait until travel plans and supporting evidence are no longer available.

What Is the Deadline for an EU261 Flight Compensation Claim?

An EU261 flight compensation claim must generally be filed within three years of the date the flight occurred or, if a flight has not yet departed, within three years of the scheduled date of departure. This deadline applies to claims for compensation under EU Regulation 261/2004 and may be extended to six years in certain national legal systems. The three-year period usually begins when passengers become aware of the disruption, but the wording and interpretation of the relevant law can vary by country. A passenger should submit a claim as soon as possible, especially when airline rebooking deadlines are short or urgent travel decisions must be made. EU261 compensation is separate from any request for a refund, rerouting, or reimbursement of expenses, each of which may have different time limits. Passengers should keep their booking confirmation, boarding pass, delay or cancellation notice, and correspondence with the airline. Filing promptly can also help passengers document the disruption and preserve their options.

No claims deadline should be confused with the airline’s deadline for providing a preferred rerouting or other immediate assistance. A passenger who misses a short rebooking window may still have a valid compensation claim, although the available remedy could be affected by the circumstances. For flights involving several airlines or complex connections, passengers should check the rules applying to each segment and confirm the final destination and operating carrier. If the three-year period is approaching, passengers should contact the airline directly and consider keeping a copy of the online submission or written claim. Legal time limits can be strict, so it is sensible to seek advice if the deadline is close or the flight was outside the EU but connected to a protected journey.

Claims and Reimbursement Process

Under EU261 Regulation, the usual deadline for seeking flight compensation is one year from the date you were scheduled to travel, assuming your flight was delayed or cancelled in circumstances covered by the law. In practice, this period may run from the original departure date, the date of rebooking, or the date you eventually reached your destination, depending on the circumstances and the national law applying to your case. You should therefore contact AI Flight Refunds as soon as possible, keeping your booking confirmation, boarding pass, and other supporting documents.

Compensation may be due for qualifying cancellations, long delays, denied boarding, or rerouting that leaves you waiting sufficiently long. EU261 flight compensation generally provides a right to payment, although the amount varies according to the distance and the disruption involved. Some claims also include reimbursement for necessary expenses, but these are not automatically payable in every situation. Because EU261 rules interact with different national limitation periods, consumers should not delay merely because the common one-year period appears straightforward. Acting promptly helps preserve your options and allows the claim to be assessed before evidence becomes harder to obtain.

EU261 Compensation Comparison

AI Flight Refunds explains that EU261 claims generally have a three-year deadline, although national laws can set different limitation periods. Because the exact deadline depends on where you purchased the ticket and the circumstances, travelers should contact the airline or a qualified claims representative promptly rather than waiting. Keeping booking details, receipts, and correspondence can help support the claim.
