ADR for Flight Claims: How Free Dispute Resolution Works

What Is ADR and How Does It Work?

ADR — Alternative Dispute Resolution — is the free, out-of-court route to settle a dispute with an airline in the UK. When a carrier rejects your EU261 or UK261 claim or simply stops replying, an approved ADR body steps in to mediate. It's designed for consumers: no lawyer, no court fees, no filing costs. Most major UK airlines are signed up to a government-approved ADR scheme.

ADR isn't a court. It doesn't hand down a binding judgment unless you accept the outcome. Instead, an independent adjudicator reviews both sides and issues a decision based on the law — chiefly Regulation (EC) No 261/2004 as retained in UK law (UK261). Once you accept, the airline is bound to pay. If you reject it, you keep every right to go to court.

When Can You Use ADR?

ADR is the second step, not the first. You must complain to the airline directly and give it a chance to respond — usually up to eight weeks — before escalating. A few conditions apply:

• Prior complaint: You must have raised your EU261/UK261 claim with the airline first and reached a deadlock or no reply.
• Approved scheme: Your airline must belong to an ADR body approved by the Civil Aviation Authority (CAA).
• No active court claim: The matter must not already be before a court or another resolution body.
• CAA fallback: If your airline isn't in an ADR scheme, you can complain directly to the Civil Aviation Authority, which handles passenger complaints itself.

The CAA publishes which airline uses which ADR body. Check the list before you file so your complaint lands in the right inbox. The two main UK schemes are CEDR and AviationADR.

Step by Step: How to File Your ADR Complaint

The ADR process is built for consumers — no legal know-how required. With your paperwork ready, you can complete a submission in under half an hour.

1. Gather your evidence: Booking confirmation, flight number, date, your correspondence with the airline, and its rejection. Keep receipts for any extra costs too.
2. Find the right scheme: Check the CAA list to see whether your airline uses CEDR or AviationADR, then open that body's online form.
3. State your claim: Be specific — for example, £350 compensation under Art. 7 UK261 for a medium-haul delay over three hours.
4. Upload your proof: Attach your documents. The clearer the evidence, the stronger and faster the adjudicator's decision.
5. Submit and wait: You'll get an acknowledgement. From here, the ADR body handles communication with the airline for you.

How Does the ADR Process Unfold?

Once your case is accepted, the ADR body asks the airline for its response and reviews both sides. An independent adjudicator then reaches a decision grounded in the law — primarily UK261 and the case law of the courts on extraordinary circumstances and compensation thresholds.

You receive the decision in writing. If you accept it, it becomes binding on the airline and it must pay. If you reject it, you lose nothing — you keep the right to bring a court claim. In England and Wales you have a generous six-year limitation period (five years in Scotland), so escalating to ADR rarely costs you time. A decision typically arrives within a few weeks to a couple of months.

Benefits and Limits of ADR

The upside is clear: ADR is free for passengers and works without a solicitor. It's faster and far less stressful than court, and most clear-cut UK261 cases end in a payout. For airlines that drag their feet, an ADR complaint is real leverage.

Know the limits, though. ADR schemes can cap the claim value they handle, and the decision binds the airline only once you accept it. ADR also isn't legal advice. For genuinely complex disputes — say, a contested extraordinary-circumstances defence — the small claims court may ultimately be the surer route to the full amount.

Frequently Asked Questions (FAQ)

How much does ADR cost?

ADR is free for passengers. The airline covers the cost of the scheme. You pay no fee and no success commission — unlike commercial claim companies that keep up to 50% of your compensation.

How long does an ADR case take?

Usually a few weeks to a couple of months — much quicker than court. The exact time depends on the complexity of the case and how fast the airline responds. Your claim stays protected within the limitation period throughout.

Is the ADR decision binding?

It becomes binding on the airline only if you accept it. If you reject it, you keep all your rights and can still sue. With most schemes the airline is bound by the outcome once you accept — so you lose nothing by trying ADR first.

What if my airline isn't in an ADR scheme?

Then you can complain directly to the Civil Aviation Authority, which handles passenger complaints against airlines outside an approved scheme. Check the CAA website for the list of participating airlines and their schemes.

Do I need a complaint letter first?

Yes. ADR only opens once you've complained to the airline and given it the chance to respond. Our generator produces a solid complaint letter for 10.00 EUR — the ideal foundation for a later ADR escalation.
