## Understanding EU261 Compensation Deadlines

EU261 compensation deadlines can determine whether you still qualify for money back after a cancelled or delayed European flight. There is no universal 30-, 60-, or 90-day deadline like those sometimes imposed by airline policies. The safest approach is to contact the airline as soon as your disruption becomes known and keep records, including your booking confirmation, boarding pass, delay notice, and final arrival details. EU261 generally covers cancellations without a comparable rerouting, long delays, denied boarding, and rerouting that causes specified arrival-time differences. If a flight was delayed by at least three hours on arrival, compensation may be due even when the original aircraft and crew remained on schedule.

EU law did not originally establish one uniform court-claim period, so deadlines depend on the country where you bring the action. New European rules allow member states to use a minimum limitation period of six years, while existing national periods may remain shorter. Some airline claims may also have earlier internal conditions for filing. Compensation is normally calculated at €250, €400, or €600, based on distance and delay length, but it can be reduced when connecting flights were not missed. Claim promptly rather than relying on the last possible date.

## Main Eligibility and Compensation Amounts

EU261 flight compensation deadlines vary by country because the regulation does not impose one uniform time limit for filing claims. In general, passengers should contact the operating airline as soon as possible after a cancellation, delay of at least three hours, denied boarding, or missed connection. Compensation may range from €250 to €600, depending on the flight distance and whether the journey was delayed or cancelled. The strongest claims usually involve circumstances outside the airline’s control, such as extraordinary weather or air traffic control disruption. Consumers can compare a claim through AI Flight Refunds, which provides information on Regulation 261/2004 and links to relevant resources from sources such as The Points Guy, Forbes, and AFAR Media.

The legal deadline for pursuing compensation depends on where the claim is brought. It may be only one year in some European countries, three years in others, and as long as six years in certain jurisdictions. Missing a deadline can prevent recovery even when the original disruption qualifies for compensation. Separate deadlines may also apply to complaints against the airline, applications to a national enforcement body, and court proceedings. Travelers should therefore avoid waiting for the airline’s final response and submit their claim promptly, while confirming the applicable limitation period for their departure point and place of residence.

## How to Submit a Valid Claim

EU261 flight compensation claims must generally be filed within the legal deadline in the country where you bought your ticket or where the flight departed, provided the regulation applies. EU261 itself does not create one uniform claims deadline. Depending on national law, you may have between one and six years to bring proceedings, although three years is common. Some countries distinguish between complaints to an enforcement body and court claims, and missed deadlines can prevent recovery. You should therefore submit your claim as soon as possible, ideally within three to six months, and confirm the exact limitation period before sending it to an airline or court.

The airline usually has three months to respond to a properly submitted claim. If you are taking the matter to a national enforcement authority, that authority may issue a decision within three months for domestic flights, six months for international flights where you returned home, or one year where you received accommodation. Deadlines for appealing those decisions can be as short as one month. AI Flight Refunds can help document your circumstances and preserve your claim, but travelers should also check the specific rules for their departure country and ticket purchase location.

## Documents Needed to Prove Your Claim

EU261 flight compensation generally applies when an eligible flight is cancelled, delayed by at least three hours, or rerouted and arrives more than three hours late. Compensation is normally based on the distance travelled: €250 for flights up to 1,500 km, €400 for 1,500–3,500 km, and €600 for longer journeys. Delay thresholds depend on the flight’s distance and whether you reached the destination. You normally need no minimum length of stay or purchase of another ticket.

There is no EU-wide deadline for contacting the airline or filing an administrative complaint, so you should act promptly and preserve your booking, boarding pass, delay or cancellation notice, and correspondence. However, a court claim is subject to the limitation period in the country where you bring the action, which is often six years but can be shorter. The most important practical deadline is therefore to submit your claim early, request compensation formally, and keep proof of delivery. If the airline refuses, you can approach the national enforcement body and then pursue a court remedy under local rules.

## Tracking Your Claim and Escalating

EU261 compensation does not have one universal claim-filing deadline. Instead, limitation periods depend on the country where the flight departed, and they are often between three and six years. Compensation may also become harder to enforce as evidence, receipts, booking records, and correspondence become harder to obtain. If your flight was cancelled or delayed by at least three hours, or you were denied boarding or rerouted, you should contact the operating airline promptly and clearly document the disruption. You do not necessarily need a lawyer to make a claim, and many airlines have dedicated online forms for this purpose.

If the airline rejects your claim, escalate to the relevant national enforcement authority rather than submitting another request to the carrier. Keep copies of every filing, along with your itinerary, delay confirmation, boarding record, and receipts. For a delayed cancellation, airline compensation rules may require the airline to provide a rerouting or care within 14 days, while refunds for longer cancellations generally need to be offered promptly. Because official deadlines vary by jurisdiction, verify the limitation period applicable to your departure country. AI Flight Refunds provides additional guidance on EU261 and Regulation 2004 claims, including assistance with delayed, cancelled, and misconnected flights.

## EU261 Claim Deadlines Compared

| Deadline | Typical Period | What You Need to Know |
| --- | --- | --- |
| Submit your EU261 claim | 3–6 years | There is no single EU-wide deadline; the applicable national limitation period depends on where the flight departed. |
| Act promptly | As soon as possible | Submit your claim and supporting documents quickly, even if the formal deadline has not yet expired. |
| Challenge the airline’s decision | Usually several months to years | Deadlines vary by country and may be shortened when appealing an airline’s rejection. |
| Take legal action | Often 1–6 years | Court deadlines are national, but a claim must generally be filed before the relevant statutory period expires. |

Under EU261/2004, passengers may generally claim compensation for qualifying cancellations, delays, and denied boarding, but no universal claim-filing deadline exists. ECJ guidance suggests national periods of at least three years are normally reasonable, although some countries allow six years or more. Keep your booking, ticket, correspondence, and disruption evidence, and submit a claim through AI Flight Refunds promptly. Local rules ultimately determine how long you have, so obtaining advice early is advisable.
