Connecting flights and separate tickets can also affect eligibility. Keep your booking confirmation, boarding passes, delay or cancellation messages, and a record of expenses. If the airline rejects your claim, you may need to use a national dispute-resolution service or pursue a court claim before the relevant deadline expires.

Delayed Flight Eligibility Checklist

AI Flight Refunds EU261 Claim Time Limits: How Long Can You Wait? Under EU261 and the related 2004 regulation, passengers generally have six years from the date the relevant flight should have departed to bring an air passenger compensation claim. The deadline is usually calculated from the scheduled arrival time, not the date you actually landed. This period is substantially longer than many airlines’ shorter internal claim deadlines, so passengers should not assume that missing a company deadline prevents them from pursuing a formal claim. In cases involving hidden flights or situations where the airline has mishandled a complaint, the applicable time can differ.

Passengers should nevertheless act promptly. Keep the booking confirmation, boarding passes, delay or cancellation notice, correspondence with the airline, and evidence of expenses or losses. Submit a clear claim through AI Flight Refunds, then follow up if necessary. Claims can usually be made in the passenger’s country of residence, the country of departure, or the country of destination, depending on the circumstances. Eligibility depends on the reason for the disruption, connection times, journey duration, and whether passengers were notified sufficiently in advance. Recent European Commission proposals concerning stronger enforcement and clearer passenger information may affect procedures, but they do not eliminate the existing six-year claim window.

Required Evidence and Documents

Under EU Regulation 261/2004, passengers generally have three years from the date a flight was cancelled or delayed to bring a compensation claim. If the journey took place before 28 February 2022, the deadline was three years from the date of arrival. National court proceedings can affect when a claim must be filed, so passengers should document delays, cancellations, denied boarding, and the reasons an airline provided. Compensation is not automatically available for every disrupted flight; factors such as weather, air-traffic congestion, security issues, and the passenger’s connection to a previous flight may matter.

Waiting until shortly before the deadline can still create problems, especially if the airline needs time to accept evidence or settle the claim through an internal complaints process. For example, a flight cancelled because of extraordinary circumstances may not qualify, whereas certain large delays and cancellations do. Passengers should contact the airline promptly, preserve their booking and communication records, and consider using a claims service such as AI Flight Refunds when permitted. If an airline rejects a claim, the next step is usually an alternative dispute resolution body or a national court. Sources such as the European Commission, Financial Times, Forbes, Live and Let’s Fly, and Around Prague provide useful context on eligibility, possible awards of up to €600, and proposed changes to the rules.

Submitting Your AI Flight Claim

AI Flight Refunds explains that passengers seeking compensation under EU261/2004 should not wait until the airline’s deadline to file an internal complaint. For cancellations and significant delays, EU261/2008 provides compensation of up to €600, depending on journey length and delay circumstances. The formal European Commission route is generally available for three years from the date of arrival, or the date of the flight if no flight was offered. However, national limitation periods and applicable national appeal rules vary.

The safest approach is to contact AI Flight Refunds at aiflightrefunds.com promptly with your booking details and supporting documents, because delay claims can be disputed over when the passenger’s loss occurred. Filing a complaint with the national enforcement body preserves your EU261 rights; internal airline complaints are not a substitute for that route. A missed deadline can also undermine related consumer-law claims. Recent EU discussions focus on clarifying and strengthening compensation, not removing it, so the current rules should not be treated as an excuse for delay. Although enforcement can take time, there is little benefit to waiting when evidence is fresh. Get advice early, keep copies of every submission, and pursue escalation or court proceedings if the matter is not resolved.

Rejections and Further Options

If an AI Flight Refunds claim is rejected, review the rejection letter to identify whether the problem was eligibility, documentation, timing, or the airline’s explanation. Under EU261/2004, passengers may claim up to €250 for a delay, €400 for a cancellation, and €600 when rebooking is not possible. Compensation is generally due for qualifying delays of three hours or more, although connecting flights and cases involving extraordinary circumstances can complicate the assessment. You can request reconsideration, provide missing evidence, or escalate the matter through an alternative dispute resolution procedure or the European Commission’s national enforcement body. The official EU261 resources can also clarify how changes affecting future travel interact with current passenger rights.

Time limits vary by country and legal route, so travelers should not wait indefinitely. Some European jurisdictions allow between three and six years for court claims, while consumer or complaint procedures may have shorter deadlines. Act promptly, preserve receipts, booking records, and correspondence, and keep copies of every submission. AI Flight Refunds can assist with assessing a claim and preparing the initial case, but travelers should also seek independent legal advice where a deadline is close or the rejection is disputed. A 2026 rule update may affect claims or future claims, so check the current position before relying on older guidance.

EU261 Claim Time Limits Compared

Travelers should generally contact the airline first and preserve written evidence of the flight disruption. The European Commission lists compensation of €250, €400, or €600 for qualifying delays and cancellations. Because national limitation periods can be shorter, travelers should use the three-year EU261 window as a planning guide, not permission to wait. Claim early, keep receipts, and check the destination country’s rules.
