Downgraded Flight Refund (EU 261/2004, Article 10)

If an airline placed you in a lower class than the one you paid for, EU Regulation 261/2004 gives you a fixed percentage refund of your ticket price. This is a specific, calculable entitlement under Article 10, separate from any goodwill voucher the airline might offer. It applies to flights departing an EU airport and to flights into the EU on EU-based carriers. You make the claim yourself and keep every cent.

Your rights

Article 10(2) of Regulation (EC) 261/2004 states that if a passenger is placed in a class lower than the one for which the ticket was bought, the operating carrier must reimburse, within seven days: 30% of the price of the ticket for flights of 1,500 km or less; 50% for intra-EU flights over 1,500 km (except to/from the French overseas departments) and all other flights between 1,500 km and 3,500 km; and 75% for all other flights, including those to/from the French overseas departments. The reimbursement is a percentage of the price of the relevant flight segment, not of any taxes or unrelated services. The Court of Justice (Mennens, C-255/15) confirmed the percentage is calculated on the price of the flight on which the downgrade occurred, including all components of that ticket price relating to the flight itself.

Step by step

1Gather evidence of the class you paid for (booking confirmation, fare class, receipt) and the class you actually flew (boarding pass, seat assignment). Keep both.
2Identify the distance band of the affected flight and apply 30%, 50% or 75%. If you bought a multi-leg ticket, calculate the percentage on the price of the segment where the downgrade occurred.
3Write to the airline citing Regulation 261/2004, Article 10(2). State the flight number, date, class paid versus class flown, the price of the affected segment, your calculated refund and your IBAN. Article 10 requires payment within seven days.
4If the airline refuses or undervalues the refund, escalate to the National Enforcement Body in the EU country of departure (or arrival for EU-carrier inbound flights), or use ADR / small claims. ECC-Net assists with cross-border cases.

What they'll say, and your comeback

“We've given you a travel voucher to make up for the downgrade.”

Comeback, Article 10(2) requires a cash reimbursement of a fixed percentage of the ticket price, paid within seven days. A voucher does not satisfy a statutory right unless I freely accept it instead.

“The downgrade was due to an operational/aircraft change beyond our control.”

Comeback, Article 10 contains no 'extraordinary circumstances' defence. Unlike cancellation compensation, the downgrade reimbursement is owed regardless of the reason for the downgrade.

“The percentage applies only to the base fare, not the whole ticket.”

Comeback, In Mennens (C-255/15) the Court held the percentage is calculated on the full price of the flight where the downgrade happened, including all flight-related components, not just a stripped-down base fare.

FAQ

I was upgraded for free on one leg and downgraded on another. Can the airline offset them?

No. The reimbursement under Article 10(2) is owed for the leg you were downgraded on. A free upgrade elsewhere is not a permitted offset against your statutory right.

Does the refund cover taxes and add-ons like extra baggage?

The percentage is calculated on the price of the flight itself. Components unrelated to carriage on that flight, such as certain taxes or third-party charges, may be excluded, but all flight-price components are included.
