How to Start a Flight Compensation Claim: Your Step-by-Step EU261 Guide

Flight delays or cancellations can disrupt travel plans, but under EU Regulation 261/2004, passengers arriving at their final destination more than three hours late may claim compensation from the airline. This guide outlines the core process: first verify eligibility based on arrival delay and exclude extraordinary circumstances, then submit a formal claim to the airline's customer service with flight details and a reference to EU261. Eligible claims range from €250 to €600 depending on flight distance, with potential 50% reductions if airlines offer re-routing that minimizes delay. Airlines must respond, but escalation to authorities like the CAA or courts follows if needed. Start by gathering your booking reference, flight number, route, date, and actual arrival time.

Check If You're Eligible for EU261 Compensation

Eligibility hinges on specific conditions under EU261. Passengers qualify if their flight delay results in arrival at the final destination three hours or more later than scheduled (thetraveler.org; bottonline.co.uk). This applies to delays or cancellations where the airline is responsible. EU Reg 261 requires airlines to compensate passengers when flight delays or cancellations result in passengers reaching their final destination more than three hours later than originally scheduled.

One key exclusion is extraordinary circumstances, where airlines avoid liability if the issue was truly beyond their control, such as severe weather or air traffic control decisions. EU261 does not make airlines pay when the cause of delay truly wasn’t within their control, clearly separating airline faults like technical issues from uncontrollable events. EU261 covers flights departing from the EU, or arriving in the EU on an EU airline, regardless of origin.

Before proceeding, confirm your arrival delay exceeds three hours at the final stop. Delays at departure alone do not trigger compensation--one important condition: the delay has to be on arrival (3+ hours later than scheduled arrival time at your final destination).

Understand Your Compensation Amount

Compensation amounts under EU261 are fixed by flight distance, helping set clear expectations. Shorter flights qualify for lower tiers, while longer ones receive more. These amounts may be reduced by 50% if the airline provides re-routing where the delay is no longer than the original schedule.

These tiers come from official breakdowns, including those on airfrance.fr and europa.eu guidelines. Measure distance between departure and arrival airports; tools from aviation authorities can help verify.

Step-by-Step Guide to Submitting Your Claim

Submit claims directly to the airline first, as required under EU261. Use their customer service portal, email, or contact form. Submit a claim to the airline’s customer service citing the regulation (EU261).

1. Gather details: Collect your booking reference, flight number, exact route (e.g., airport codes), date of flight, scheduled vs. actual arrival times, and boarding pass or ticket.

2. Reference EU261/2004: State clearly that you are claiming under Regulation (EC) No 261/2004. Airlines recognize this phrasing.

3. Explain entitlement: Describe what happened--delay or cancellation--and why you qualify (e.g., over three hours late at final destination, no extraordinary circumstances). Set out exactly what happened with your flight, why you believe you are entitled to compensation, and the amount you wish to claim as per your rights under Regulation EU 261/2004. Clearly state the compensation amount you are claiming based on the flight distance. Note the compensation amount based on distance.

4. Attach evidence: Include screenshots of delays from airline apps, airport screens, or official announcements. Provide flight details: Include your flight number, route, date.

5. Send and track: Submit via the airline's form, keeping records of submission date. Precise details matter. Templates from sites like thebrokebackpacker.com serve as starting points to structure your letter--I've drafted a couple of templates that you can use as a starting point.

Airlines typically have 28 days to respond, though timelines vary.

What to Do If the Airline Rejects or Delays Your Claim

If the airline denies your claim or fails to respond within a reasonable time, escalate systematically. First, contact the relevant national aviation authority, such as the UK's Civil Aviation Authority (CAA) for flights involving the UK. Provide your full correspondence with the airline.

Authorities review free of charge and can enforce payment. If unresolved, the final option is small claims court proceedings in the airline's EU country or your home jurisdiction--if you still haven’t progressed, even after consulting the CAA, your only remaining option is to issue Court Proceedings. This path follows authority consultation.

Keep all emails and evidence organized for these steps.

Should You Handle the Claim Yourself or Use a Service?

DIY claims cost nothing and give full control, following the steps above directly with the airline. You retain 100% of any payout and learn your rights under EU261.

Third-party services like AirHelp handle paperwork and follow-ups for a fee, often 25–50% of compensation if successful--AirHelp helps you claim under EU Regulation 261/2004. They are useful for complex cases or if you prefer not to manage escalation. Weigh time investment: self-submission suits straightforward delays.
