Writing your own EC261 claim letter sounds straightforward: tell the airline what happened and ask for money. In practice, airlines process thousands of claims daily through automated triage systems. Letters that miss key elements, use the wrong tone, or fail to cite the regulation correctly are flagged for rejection or pushed to the bottom of the queue. Getting the structure right matters more than most passengers realise.
Key takeaways
What makes a strong claim letter
- Include every required element — one missing detail gives the airline an excuse to delay
- Cite EC261/2004 and Article 7 explicitly — vague complaints get ignored
- State the exact compensation amount (€250, €400, or €600) — do not leave it open
- Set a 14-day deadline and state your intention to escalate if ignored
The essential elements
Every EC261 claim letter needs the same core components. Missing any of these gives the airline a procedural reason to delay or reject, adding weeks or months to the process.
1. Your contact details
Start with your full legal name, postal address, email address, and phone number. The name must match the booking exactly. Airlines will reject claims where the name does not match their records, even for minor discrepancies like middle names or hyphens.
2. Flight details
Include the flight number (e.g., LH1234), the date of the flight, the departure and arrival airports, and your booking reference or confirmation number. These are the fields the airline uses to locate your record in their system. Without them, your claim cannot be processed.
3. A factual description of the disruption
Describe what happened in precise, factual terms. Do not write "my flight was very late" or "the airline ruined my holiday." Instead, state the specifics: "Flight FR1234 arrived at Milan Malpensa at 23:47, 4 hours and 12 minutes after the scheduled arrival time of 19:35." For cancellations, state the date you were notified. For denied boarding, state that you held a valid reservation and arrived at the gate on time.
Precision matters
Airlines often dispute delay duration by minutes to push it below the 3-hour threshold. Stating exact times — and referencing flight tracker data — makes your claim harder to contest.
4. The legal basis and compensation amount
Explicitly reference Regulation (EC) No 261/2004 and Article 7. State the specific compensation amount you are claiming — €250, €400, or €600 — based on flight distance. Do not write "I would like to be compensated" or leave the amount vague. Airlines treat specific, legally grounded claims differently from general complaints.
5. Payment details
Include your bank account details (IBAN and BIC/SWIFT) in the letter itself. Airlines sometimes delay by acknowledging the claim and then asking for payment information weeks later. Providing it upfront removes this stalling tactic.
6. A deadline and escalation statement
State that you expect a response within 14 days and that you will escalate to the national enforcement body and, if necessary, pursue the claim through court proceedings if the deadline is not met. This is not a threat — it is a factual statement of your available options, and it signals to the airline that you will not simply give up.
Common mistakes that get claims rejected
Even when passengers include the right information, certain mistakes consistently lead to rejections or delays.
Emotional language. Describing your frustration, ruined holiday, or sleepless night at the airport adds nothing to an EC261 claim. Compensation is a fixed statutory entitlement based on the facts of the disruption, not a damages claim based on suffering. Every sentence that does not support the factual or legal basis of your claim is noise that makes the letter less effective.
Not citing the regulation. A letter that says "I want compensation for my delayed flight" is processed as a customer complaint. A letter that says "I am claiming €400 under Article 7 of Regulation (EC) No 261/2004" is processed as a legal claim. The distinction matters for how the airline routes and prioritises your case.
Wrong airline. Your claim must be addressed to the operating carrier — the airline that actually flew the route. On codeshare flights, this may differ from the airline you booked with. Sending a claim to the wrong airline wastes weeks.
Generic template language. Airlines recognise common templates circulating online. While a template is a fine starting point, letters that are clearly copy-pasted without personalisation may receive a template rejection in return. Adapt the structure to your specific situation.
Do not accept less than the full amount
If the airline responds with a lower offer, a voucher, or a "goodwill gesture", you are under no obligation to accept. Reply firmly stating the statutory amount and your intention to escalate. See our guides on partial payment offers and cash vs vouchers.
Why airlines reject — and what happens next
Even well-written claims are frequently rejected on the first attempt. Some airlines reject virtually every claim as a matter of policy, citing extraordinary circumstances with minimal evidence, betting that most passengers will not follow through. Others delay for months without responding, hoping you will forget.
This is where the process becomes time-consuming. If the airline rejects your claim, you need to evaluate their defence, write a rebuttal, and potentially escalate to the national enforcement body or court. Each round of correspondence adds weeks or months. For passengers handling this themselves alongside work and life, the process often stalls — which is exactly what the airline is counting on.

What to do if the airline does not respond
If you do not receive a response within 14 days, send a brief follow-up referencing your original letter and the date it was sent. If there is still no response after six to eight weeks total, it is time to escalate. File a complaint with the national enforcement body in the country of departure, or submit to an alternative dispute resolution scheme if one is available.
Most initially ignored claims are resolved after escalation. Airlines count on passengers giving up. A clear paper trail showing you claimed, waited a reasonable period, and then escalated demonstrates seriousness and strengthens your position at every stage.
