Glossary entries are desk-researched definitions for July 2026, not legal or financial advice. ## What is EU261? EU261 (Regulation EC 261/2004) is the European Union law that can require airlines to provide care during long disruptions and to pay standardised compensation for certain delays, cancellations and denied boarding on qualifying flights. In plain terms: if your journey is in scope and the airline is responsible, long arrival delays, short-notice cancellations and involuntary denied boarding can trigger fixed compensation bands that scale with distance. Extraordinary circumstances (for example some weather or security events) may remove the cash band while care duties can remain. Operating carrier identity matters on [codeshares](/guides/what-is-codeshare). This glossary entry is the definition layer. For eligibility tables, distance bands and claim paths, use [EU261 compensation complete rules](/guides/eu261-compensation-complete-rules). UK journeys often fall under a parallel regime — [what is UK261](/guides/what-is-uk261). whether your ticket is EU261, UK261-adjacent, or outside both. Start a screen with the [compensation checker](/tools/compensation-checker) and DIY steps in [how to claim flight compensation DIY](/guides/how-to-claim-flight-compensation-diy). Distance bands and delay thresholds are the maths most passengers care about; extraordinary-circumstances disputes are the argument most airlines raise. Keep boarding passes and a timeline even if the airline already sent a delay SMS. Package holidays can add organiser duties alongside EU261 — keep both contracts if a tour company booked the flights. ## Which flights usually fall under EU261? Planning shorthand: flights departing an EU airport on any airline, and flights into the EU on an EU carrier, are the usual starting points — always confirm operating carrier and final-arrival delay. Example: a Paris–New York flight departs five hours late for a crew-scheduling issue with no extraordinary-circumstances defence; you arrive beyond the threshold and later claim a distance-based amount. A weather closure that strands everyone may still bring hotel care without cash compensation. Full scenarios: [EU261 complete rules](/guides/eu261-compensation-complete-rules). Denied boarding from [overbooking](/guides/what-is-overbooking) on a qualifying flight can use the same framework — see [denied boarding compensation](/guides/denied-boarding-compensation-explained). ## Which terms sit next to EU261?

Claim in writing directly with the operating airline, citing Regulation EC 261/2004, your flight details and arrival delay; attach boarding passes and receipts, state the statutory amount (EUR 250–600), and escalate to the national enforcement body if refused. EU261 pays fixed compensation for arrival delays over three hours, cancellations under 14 days’ notice and denied boarding — EUR 250 for flights up to 1,500 km, EUR 400 to 3,500 km, EUR 600 beyond. The trigger is arrival time at your final destination, not departure, and the cause must not be “extraordinary circumstances” like severe weather or air-traffic strikes. Airline crew strikes and technical faults generally do qualify. Build the file before writing: booking confirmation, boarding passes, and any photos of departure boards or airline messages stating the reason. Submit through the airline’s own claims form or email, name the regulation, and request bank transfer — you are entitled to money, not vouchers, unless you accept otherwise. Keep the tone factual; template letters work because the law is mechanical. Expect resistance: some carriers ignore first claims or cite false extraordinary circumstances. Reply once with evidence, then escalate to the national enforcement body of the country where the disruption happened, or use small-claims court — both are free or cheap and routinely side with passengers. Claims agencies take 25–35% for the same letters; our [how to claim flight compensation DIY](/guides/how-to-claim-flight-compensation-diy) and [flight delay compensation rights](/guides/flight-delay-compensation-rights) guides give you everything they use. --- Canonical HTML: https://travelshifu.com/guides/what-is-eu261/ Last modified: 2026-07-21
