Your rights

Under EU Regulation 261/2004 (often called EU261 or UK261 in the UK), you are entitled to financial compensation if your flight is delayed by three hours or more upon arrival. This applies to flights departing from an EU or UK airport, or flights arriving in an EU or UK airport operated by an EU or UK airline. The compensation amount depends on the flight distance and the length of the delay, and is not dependent on the ticket price. Airlines are only exempt if the delay was caused by 'extraordinary circumstances' that could not have been avoided, even if all reasonable measures had been taken. This typically excludes routine technical faults or staff shortages, but includes severe weather or air traffic control strikes.

Step by step

1Confirm your eligibility. Your flight must have been delayed by at least 3 hours on arrival. Check if the delay was due to 'extraordinary circumstances' like severe weather or an air traffic control strike, as these are usually exempt. Routine technical issues or operational problems are generally not extraordinary.
2Gather all necessary documentation. Collect your booking confirmation, boarding passes, and any communication from KLM regarding the delay. Note the exact departure and arrival times, and the length of the delay. Take screenshots of flight tracking information if possible.
3Contact KLM directly to make your claim. Use their official online compensation claim form, which is usually found in the 'Customer Support' or 'Contact Us' section of their website. Clearly state your flight details, the delay duration, and that you are claiming compensation under EU261/UK261.
4Escalate your claim if necessary. If KLM rejects your claim, offers vouchers instead of cash (you have a right to cash), or fails to respond within a reasonable timeframe (usually 6-8 weeks), contact the relevant national enforcement body. In the UK, this is the Civil Aviation Authority (CAA). For other EU countries, check the list of national enforcement bodies provided by the European Commission.

What they'll say, and your comeback

“The delay was due to 'extraordinary circumstances'.”

Comeback, I understand that extraordinary circumstances can occur. However, routine technical faults, staff shortages, or operational issues are generally not considered extraordinary under EU261/UK261. Please provide specific evidence that the cause of the delay was genuinely unavoidable, despite all reasonable measures being taken, and was outside of your control.

“We can offer you flight vouchers or miles instead of cash compensation.”

Comeback, Thank you for the offer, but under EU261/UK261, I am entitled to financial compensation in cash, bank transfer, or cheque. I insist on receiving the compensation I am legally owed in monetary form.

“Your claim is outside the time limit.”

Comeback, The time limit for claiming compensation varies by country. In many jurisdictions, it can be several years. Please confirm the specific legal basis for your assertion that my claim is out of time, as I believe it falls within the applicable statutory period.

FAQ

How much compensation can I expect?

The compensation amounts are fixed by law: €250 for flights up to 1,500 km, €400 for flights between 1,500 km and 3,500 km (or over 1,500 km within the EU), and €600 for flights over 3,500 km outside the EU. These amounts are per passenger.

What if KLM offers me food and drink during the delay?

Airlines are required to provide care and assistance, including meals, refreshments, and accommodation (if an overnight stay is needed), for significant delays. This is separate from your right to financial compensation. Accepting these provisions does not affect your right to claim compensation.
