What Counts as Evidence for an EU261 Claim?
EU261 compensation is not based simply on a passenger’s belief that the airline was late. To pursue a credible claim, you need evidence connecting your booking, itinerary, disruption, arrival delay, and eligible journey to the airline. The central documents are your booking confirmation, ticket or electronic ticket record, boarding passes, and a delay or cancellation notice. A carrier’s website may also publish the reason for the disruption, but passengers should save screenshots because those pages can later change or disappear.

The strongest evidence usually includes the scheduled departure and arrival times, the actual departure or cancellation time, and the eventual arrival time in the European Union. Keep the airline’s emails, text messages, rebooking messages, refund correspondence, and airport records. If the disruption followed a strike, severe weather, air-traffic-control restrictions, or an operational decision, the stated reason does not necessarily remove compensation rights. Airline-caused technical, staffing, or scheduling problems are not automatically excluded simply because the airline labels them operational.
Proving eligibility is different from proving the exact compensation amount. An arrival delay of at least three hours can support a standard EU261 claim, but the applicable rule may depend on the flight’s departure and arrival locations. The airline should investigate the original flight under the flight-number rule, not merely the replacement flight, although the replacement details can help reconstruct events. Screenshots, PDFs, photographs, app confirmations, bank records, and personal notes are useful, but a handwritten statement alone rarely resolves a factual dispute.
EU261 Compensation Thresholds and Possible Amounts
Regulation (EC) No 261/2004 generally provides compensation for certain passengers whose flights are cancelled or delayed by at least three hours on arrival because of an eligible disruption. The standard amounts are €250, €400, or €600, depending mainly on the length of the scheduled air journey. These are the headline compensation figures, not necessarily the amount a passenger receives after deductions, set-offs, taxes, or a settlement with the airline.
Compensation may be reduced by up to 50% when the passenger took a replacement flight and the original journey was significantly shortened. Cancellation can also produce a different remedy depending on whether the passenger chose reimbursement or rebooking. A passenger who voluntarily changes plans may lose the automatic connection to the original disruption, while someone who accepted a replacement flight usually has a stronger evidentiary link. Care, meals, and hotel costs are separate from fixed compensation and may be owed even where fixed compensation is not.
| Feature | Arrival delay of 3+ hours | Cancellation or major rebooking | Shortened replacement journey |
|---|---|---|---|
| Core evidence | Original and actual flight times | Cancellation notice and passenger choice | Original and replacement itineraries |
| Possible fixed amount | Usually €250, €400, or €600 | Usually €250, €400, or €600 | Often reduced by up to 50% |
| Other assistance | Meals and care may be separate | Refund or rerouting rules apply | Actual travel-time loss matters |
The Best Documents to Collect After a Disruption
Start with a complete travel-file folder rather than forwarding random screenshots. Download the original confirmation, ticket, itinerary, and receipt, then add a second screenshot showing the final boarded flight. Preserve messages in their original format with visible dates and times. Do not crop away the airline logo, reference number, subject line, or surrounding text, because context helps establish that the message concerned your journey.
For a delayed flight, compare the scheduled arrival time published for the original flight with the actual arrival time recorded by the airport or airline. A three-hour threshold is generally calculated from the scheduled arrival to the actual arrival, rather than from departure. However, unusual routing and cancellation rules can change how the test is applied. Document any connecting-flight deadline, especially if the replacement itinerary caused you to miss a connection or sleep in an airport hotel.
For a cancellation, save the notice that first communicated the cancellation, not merely a later confirmation that the journey was cancelled. Record what choices were offered: refund, rebooking, or rerouting. If you accepted a replacement flight, keep the new booking confirmation and any fare-difference message. If you travelled anyway, document how long it took and why you abandoned the original schedule.
Airport and third-party records can help, but their reliability varies. Flight-tracking databases may estimate rather than record exact arrival times. Airline systems may use local time while the evidence you need concerns a different time zone. Screenshots from airport websites, airline apps, airport staff emails, hotel invoices, and payment statements can therefore reinforce one another without creating inconsistencies.
Airline-Reported Delay Reasons Do Not Always Decide Eligibility
Passengers often focus on the airline’s reason code, but the reason itself is not a complete legal test. A technical fault, staffing shortage, late inbound aircraft, or missed rotation may be treated as an airline responsibility. Severe weather, security instructions, political instability, and air-traffic-control decisions may fall outside the airline’s control. Extraordinary circumstances are not, however, simply anything that caused the delay; the evidence must support the precise legal reason claimed.
Strikes need careful treatment because labour disputes may or may not qualify as extraordinary circumstances depending on how the disruption affected the specific airline and whether another reasonable operational response was available. Security events may be excluded in some cases, but a vague security mention does not prove the legal defence. Similarly, an airline saying that an airport was congested does not establish that the delay was caused by an external event rather than its own scheduling or ground operations.
Do not argue only from emotion or inconvenience. A strong submission compares the official schedule, actual movement, disruption reason, replacement option, and arrival shortfall. If the reason is unclear, ask the airline for its disruption classification and written explanation. That request creates a dated record, although the airline may not be legally obliged to disclose every internal operations report.
How Airline and Passenger Records Can Conflict
Claims are easier when the airline’s systems tell the same basic story. In practice, they may not. A departure message may show the scheduled time, a boarding pass may show the revised time, and an airport record may list the arrival after the flight was diverted. A passenger may remember arriving at 11:30 p.m., while the official record shows a flight that arrived before midnight, making the apparent three-hour delay disappear.
When records conflict, keep both versions and explain the sequence rather than guessing which one is correct. Compare time zones, daylight-saving changes, and the definition of the scheduled arrival. Also distinguish arrival at the airport from gate arrival, taxi-in time, and passport or baggage-claim time. The legal measurement generally concerns the scheduled and actual arrival time for the relevant flight, not the time a passenger reached the terminal.
Diverted flights require extra care. If the aircraft arrives at a different airport, the final arrival may still matter, but the passenger’s onward journey may add further losses. Keep the diversion notice, distance from the original destination, transfer arrangements, and hotel or rail expenses. A diversion does not automatically trigger every standard cancellation refund or compensation entitlement, so the precise itinerary should be reviewed separately.
How to Submit and Escalate an Airline Claim
Send a concise written claim to the operating carrier first, attaching the essential records and asking for an eligibility decision. Include your full name exactly as it appears on the booking, booking reference, flight numbers, original route, disruption date, scheduled and actual times, and requested remedy. State whether you seek €250, €400, or €600 only after identifying the likely distance band; otherwise, ask the airline to assess EU261 eligibility and explain its decision.
Ask the airline to respond in writing and explain whether compensation is being denied under extraordinary circumstances. A response such as “we consider it operational” should not be accepted as the end of the analysis without a stated basis. Preserve the submission and acknowledgment, then set a reasonable follow-up reminder after the airline’s stated response period. Do not repeatedly send duplicative claims from several email accounts, because that can obscure the original case and delay review.
If the airline refuses and internal appeals do not resolve the dispute, use the national enforcement body or consumer forum in the country where the airline is established, as applicable. Many passengers also use a third-party claims company, but fees and service quality vary. A representative can reduce administrative work, but it cannot create stronger evidence, guarantee success, or change the statutory requirements. Review the agreement before paying and distinguish an administration fee from any success fee.
What Compensation Services May Cost
There is no normal universal “EU261 fee” because the pricing depends on the provider, the service, and the consumer arrangement. Some companies offer free initial assessment or no upfront charge, then deduct a percentage from any recovered compensation. Others charge a fixed administrative fee, or request payment even when the claim is unsuccessful. In some cases, a legal representative’s costs are instead governed by an agreement or applicable court rules.
The amount recovered may be lower than the headline €600 figure, particularly when the journey was significantly shortened, when a settlement is negotiated, or when deductions are explained. Ask whether the fee is calculated from the gross award or the amount actually received. Obtain a written quote, cancellation terms, data-processing information, and a clear statement of who handles complaints.
A useful comparison is not simply “free” versus “paid.” Compare total net recovery, the scope of help, the evidence required, transparency, and the provider’s willingness to work under a no-win arrangement. No reputable provider should promise a particular result before seeing the itinerary, disruption reason, route, and records. The passenger remains responsible for accurate information and should not exaggerate expenses or submit unrelated claims.
Common Mistakes That Weaken EU261 Cases
The most damaging mistake is failing to prove the journey. Booking confirmations without the flown segment, or passenger accounts without official times, leave gaps. Another common error is assuming every EU flight qualifies. The route, carrier, departure point, arrival point, and operating arrangement must be checked against the regulation, including flights between the EEA and certain countries outside the EU.
Do not confuse a missed connection with a delayed flight without analysis. A three-hour delay can affect a connection, but the final obligation may arise from the disrupted flight or from the cancellation of the onward segment. Similarly, a boarding-pass screenshot does not show the scheduled arrival time. A claim should include enough information to reconstruct the original schedule and what actually happened.
Many cases fail because passengers wait too long, delete messages, or accept an informal airline response without obtaining a decision. Others fail because they exaggerate the disruption or misstate the final arrival. Keep copies, use exact dates, and respond to requests for clarification. If a deadline is approaching, submit a properly documented claim and ask the relevant body about late acceptance rather than assuming a claim remains open indefinitely.
When Passengers Should Act
Evidence is easiest to obtain while the booking is still visible in an airline account and while airport information remains online. Send a preservation request immediately after a major disruption, download the documents the same day, and maintain a dated file throughout the journey. A 2026 claim may involve several linked flights, so keep each ticket segment and message rather than combining everything into an ambiguous itinerary.
The airline’s formal refusal date matters for the next complaint stage. In many European systems, the enforcement route depends on where the airline is based, not merely where the passenger lives or where the disruption occurred. Because procedural deadlines differ, check the current rule with the relevant national authority or consumer body. A claim service can handle this, but the passenger should still verify the dates and jurisdiction independently.
The best practical approach is to act before making assumptions. Collect the schedule and actual records first, identify the apparent three-hour delay or cancellation, then evaluate the route and disruption reason. This process is especially valuable when an AI travel booking agent proposes an alternative flight: preserve the original search, confirmation, and price record, and compare the replacement journey with the booked itinerary. The agent can help organise booking evidence, but the passenger must verify the final tickets and disruption facts before submitting a claim.
A Practical Evidence Standard
A defensible EU261 claim is usually less complicated than passengers fear. It should answer four questions in order: who sold or operated the flight, where it was scheduled to go, what actually happened, and when did the passenger arrive or choose a remedy. The supporting file should make those answers visible without requiring extensive argument. A concise chronology with attached official documents is often more persuasive than a long, emotionally charged narrative.
As of 2 October 2026, the practical baseline remains broadly the 2004 EU regulation, including its three-hour arrival-delay threshold and standard €250, €400, and €600 bands, subject to route, journey-length, shortening, and extraordinary-circumstances rules. Airline delays reported in airports or on travel-tracking sites can indicate a need for evidence, but they do not by themselves decide an individual claim. Accurate records, careful timing, and a route-specific legal analysis remain more valuable than any generic online promise.
