EC 261/2004 is the most powerful passenger rights regulation in the world - and the least known. Since taking effect in 2005, it has entitled millions of European travelers to between €250 and €600 in compensation for flight delays, cancellations, and denied boarding. Yet the European Commission estimates that only 1 in 20 eligible passengers actually files a claim, leaving roughly €5 billion in legitimate compensation unpaid every year. The reason is straightforward: airlines benefit from your ignorance, and the regulation is genuinely complex.
At Gyro, we file thousands of EC 261 claims annually, and we've seen exactly which arguments airlines use to refuse valid claims, which exemptions are misused, and what evidence shifts cases in passengers' favor.This guide gives you everything: who qualifies, how much you can claim, the exceptions that genuinely exempt airlines, and the step-by-step process to win your claim.
You qualify when three conditions are met simultaneously.
You also need to have had a confirmed booking and checked in on time. The compensation is per passenger, including children with paid tickets. A family of four on a long-haul delayed flight can therefore claim €2,400 in total.
Compensation is based on flight distance, not ticket price or fare class.
From our claims experience: airlines occasionally try to pay the reduced €300 amount for long-haul delays exceeding 4 hours. The 50 percent reduction only applies when the delay is between 3 and 4 hours on long-haul routes, and since the exact length of your delay is measured at arrival, confirming your true arrival time is what determines whether you're owed €300 or the full €600.
This is the single most contested provision in EC 261. Airlines invoke it constantly to refuse valid claims; the Court of Justice of the EU has repeatedly narrowed it.
Genuinely extraordinary circumstances (airline exempt from compensation):
NOT extraordinary circumstances (airline still liable):
From our claims experience: roughly 40 percent of refused EC 261 claims cite "extraordinary circumstances" inappropriately. The leading misuse in 2025 was citing "technical issues" as extraordinary - which is clearly contradicted by the Wallentin-Hermann ruling. If your refusal cites technical issues, challenge it directly.
Airline compliance varies dramatically, and knowing the patterns helps you frame your claim.
From our claims experience: ultra-low-cost carriers (Ryanair, Wizz Air, Volotea) account for over 60 percent of EC 261 disputes we handle, despite carrying a smaller share of total passengers. Budget your time accordingly.
Time limits are set by each member state's national law, not by EC 261 itself, leading to wide variation.
Generally file with the NEB of the country where your flight departed. From our claims experience: shorter windows are easier to miss than passengers realize. Evidence quality also decays - airline communications get archived, witnesses forget details, departure board photos get deleted from phones. File as soon as you have the basic facts.
The evidence package is the same whether claiming directly, through an NEB, or in court.
From our claims experience: the airline's written refusal letter is the most-missed piece of evidence. Verbal refusals at the airport or via chatbot don't count. Always demand the airline put their refusal in writing - this is what NEBs and courts need to act.
The escalation ladder is well-established and most claims resolve before court.
EC 261 is the most generous, most enforceable, and most underused passenger rights regulation in the world. The amounts are real - €250 to €600 per passenger - the rules are clear, and twenty years of Court of Justice rulings have consistently strengthened passenger protections rather than weakening them. The single largest obstacle to collecting what you're owed is the airlines themselves, who systematically refuse valid claims hoping you'll give up.
The pattern from our thousands of claims is unambiguous: passengers who cite specific EC 261 articles, demand in writing, and escalate to NEBs when refused succeed at roughly three times the rate of passengers who only complain by phone. Documentation beats argument. A clear paper trail beats an angry email. Process beats outrage.
If you've had a flight disrupted in the last 1 to 6 years (depending on the country of departure), you can likely still claim under EC 261. The deadlines are shorter than people think, and evidence decays, so the right time to file is now.
Most eligible passengers never file an EC 261 claim - and the €5 billion in unclaimed compensation each year shows it. Gyro fixes that with a free eligibility check. You keep every euro of the €250 to €600 the airline pays, plus any care expense reimbursements.
You qualify when the flight is EU/UK-connected, significantly disrupted, and the airline was at fault.
Genuinely uncontrollable events qualify, but the list is far narrower than airlines claim.
