You reach the gate, boarding pass in hand, and an agent tells you the flight is full. Overbooking is a legal commercial practice, but it is tightly regulated by European Regulation EC 261/2004. Unlike delays or cancellations, denied boarding triggers rights that apply immediately, at the airport — and airlines have very few ways to avoid paying compensation. Here is exactly what you can demand and how much you can claim.
Why airlines overbook
A predictable share of passengers never shows up for departure. Airlines therefore sell more seats than the aircraft holds in order to maximise load factors. When the forecast is wrong, someone has to stay behind. Other situations also count as denied boarding: a last-minute aircraft swap to a smaller model, crew repositioning, or an error in the passenger list.
Step 1: the airline must call for volunteers first
Article 4 of the Regulation sets out a strict sequence. Before removing anyone against their will, the airline must ask for volunteers willing to give up their seat in exchange for negotiated benefits (vouchers, miles, hotel night, free ticket).
- If you volunteer, you negotiate the compensation freely. By accepting, you generally waive the fixed statutory amount — but you keep the right to a refund or re-routing, plus assistance.
- If you refuse to volunteer and are offloaded anyway, this is involuntary denied boarding, which triggers fixed compensation.
Practical tip: never sign a document labelled "waiver", "final settlement" or "release" without reading it. A €150 voucher can cost you a €600 entitlement.
Step 2: three rights you can demand on the spot
In case of involuntary denied boarding, three rights apply cumulatively.
1. Fixed compensation, payable immediately, based on flight distance:
- €250 for flights of 1,500 km or less;
- €400 for intra-EU flights over 1,500 km and all other flights between 1,500 and 3,500 km;
- €600 for non-EU flights over 3,500 km.
The amount may be reduced by 50% if the airline re-routes you and you reach your final destination less than 2 hours late (flights up to 1,500 km), 3 hours (1,500–3,500 km) or 4 hours (over 3,500 km).
2. A choice between refund and re-routing (Article 8): either a refund of the unused portion of your ticket within 7 days, including a return flight to your original departure point if relevant; or re-routing to your final destination at the earliest opportunity, or on a later date of your choosing. The choice is yours, not the airline's.
3. Care and assistance (Article 9): meals and refreshments proportionate to the waiting time, two phone calls or emails, and — if re-routing means an overnight stay — hotel accommodation and airport transfers. Keep every receipt if you pay out of pocket.
Eligibility conditions to check
- You held a confirmed reservation on the flight;
- You presented yourself for check-in at the stated time (or, if no time was indicated, no later than 45 minutes before departure);
- The flight departed from an EU airport (any airline), or arrived in the EU on an airline holding an EU operating licence;
- The ticket was bought at a publicly available fare or issued through a frequent flyer programme.
Note that UK departures are covered by UK261, a mirrored regime with equivalent amounts in pounds sterling.
When the airline can legitimately refuse compensation
The Regulation allows reasonable grounds for denied boarding that do not give rise to compensation: incomplete or invalid travel documents (expired passport, missing visa or ESTA), obvious health concerns, safety or security reasons, or disruptive behaviour. However, the airline's own slowness at check-in, a system error or a commercial oversell are not valid grounds. Crucially, unlike delays and cancellations, the "extraordinary circumstances" defence does not apply to overbooking: selling more seats than available is a commercial decision entirely within the airline's control.
What to do at the airport
- Ask for written confirmation of the denied boarding and the reason given;
- Photograph your boarding pass, the gate, the departure board and the time;
- Note the agent's name and record your new flight number;
- Keep all expense receipts (food, hotel, taxi, train);
- Do not sign any settlement under pressure.
You have up to 3 years to claim
Under the limitation period applicable in France, you can claim compensation up to 3 years after the flight date. A 2023 or 2024 denied boarding may therefore still be actionable. If the airline paid nothing at the gate — which is extremely common — the claim can be built retrospectively, through an amicable procedure, using your documents.
Claiming without the paperwork headache
Airlines Quick Refund reviews your file, identifies the applicable compensation band and handles the amicable claim with the airline. Our fee is 35%, success-based only: nothing to pay if the claim does not succeed. We do not provide legal or court representation advice; our role is limited to out-of-court claim handling.
