Airline refuses your EC 261 claim: 7 next steps that work

You submitted a clear, well-documented compensation claim under Regulation (EC) 261/2004. The airline:

• Refused outright invoking "operational reasons" or "technical issue"
• Offered a voucher worth less than the legal amount
• Asked for more documents to delay the process
• Sent you in circles between departments
• Or simply ignored you for weeks

This is unfortunately common. The good news: 80% of these refusals are contestable with success. Here are the seven steps that work, ranked from least to most assertive.

Step 1 — Decode the refusal against CJEU case law

First, read the refusal letter carefully. Most refusals fall into predictable patterns, all of which have been addressed by the CJEU:

Identify which pattern matches your refusal. Use the corresponding ruling in your next letter.

Step 2 — Send a formal escalation letter (mise en demeure)

Write a formal letter to the airline's customer relations department:

• By certified mail with return receipt (LRAR in France), OR
• By email to the official customer service address with a read receipt request

Include:

1. Your reservation reference and flight details
2. The exact amount you are claiming and its legal basis
3. Citation of the CJEU ruling that defeats the refusal ground
4. A deadline (typically 30 days) for payment
5. A warning that you will escalate to the National Enforcement Body and/or court

Sample formal letter

"Subject: Formal demand for compensation under EC Regulation 261/2004

Flight: [number, date, route]
Booking reference: [PNR]
Passengers: [number]

I refer to your letter of [date] refusing compensation on the grounds of [refusal reason].

This ground is contrary to settled CJEU case law: [cite ruling]. Pursuant to Article 7 of Regulation (EC) 261/2004, the compensation of €[amount] per passenger is due, totalling €[total].

I hereby formally request payment within 30 days of receipt of this letter. In default, I will refer the matter to the National Enforcement Body and seize the competent court without further notice."

Step 3 — Escalate to the National Enforcement Body (NEB)

Each EU/EEA Member State has designated a National Enforcement Body responsible for EC 261 enforcement:

You file a complaint with the NEB of the country of departure or where the disruption occurred. The NEB will investigate and may sanction the airline. However, NEBs do not order payment to passengers — they only issue findings. For payment, you still need a court.

NEB complaints are useful as extra pressure on the airline.

Step 4 — Use the European Online Dispute Resolution (ODR)

For online bookings, the European ODR platform (ec.europa.eu/consumers/odr) lets you submit a complaint that is routed to an Alternative Dispute Resolution (ADR) body recognised by the airline.

Free, online, but the airline must accept ADR. Some do (KLM, Lufthansa Group…), others refuse (Ryanair, Wizz Air…). Check first.

Step 5 — Submit a European Small Claims Procedure

For claims under €5,000, the European Small Claims Procedure is available. Standardised forms, available in all EU languages, around €35 filing fee, decision within 30 days of response.

Particularly useful if you want to seize a court in another Member State (e.g. you're a French passenger claiming against an Italian airline in Italian court for a Rome-Paris flight).

Step 6 — Mandate a professional recovery service

If you don't want to handle the procedure yourself, a specialised service like Robin des Airs can take over. We:

• Analyse your case for free against EC 261 + CJEU case law
• Send the formal letter on our letterhead (carrying more weight)
• Escalate to court if needed (with our lawyer network)
• Work on success-fee basis only: 25% commission on amounts recovered, nothing if no recovery

It costs less than hiring a lawyer yourself, and the success rate on technical refusals is ~85%.

Step 7 — Seize the competent court

If all else fails, you can sue the airline. Jurisdiction:

• Court of departure (where the delayed/cancelled flight departed)
• Court of arrival (where you were supposed to arrive)
• Or the airline's seat

Reference: flightright/Air Nostrum ruling (CJEU, C-274/16) — you choose. Pick the most convenient court.

For amounts under €5,000-€10,000, small claims procedure applies in most countries. No lawyer required, low filing fee (€30-€100 in France), decision within a few months. Most courts award costs to the winning party.

What NOT to do

• Don't accept a partial offer in writing. Once you sign, you may extinguish your full rights.
• Don't accept a voucher as full settlement unless its value clearly exceeds your legal entitlement.
• Don't wait years. Limitation periods vary (5 years France, 3 years Germany, 2 years Italy/Spain). Act within 2 years to be safe.
• Don't argue on the phone with customer service — only written exchanges have legal value.
• Don't give up after the first refusal. Airlines refuse en masse, then pay when seized in court.

Probability of success by escalation stage

Timeline expectations

• Initial claim: 30-60 days for airline response
• Formal letter: another 30 days
• NEB complaint: 60-90 days for finding
• Court (small claims): 3-6 months
• Court (regular procedure): 6-18 months

Most cases settle within 4-8 months when escalated properly.
