What EU261 Compensation Covers
An EU261 claim eligibility calculator works by processing the key facts of your flight disruption against the rules set out in Regulation 261/2004. You typically enter details such as your departure and arrival airports, the airline, the length of the delay or whether the flight was cancelled, how late you actually arrived at your final destination, and how much notice you were given before a cancellation. The calculator then determines whether your route falls under EU261 jurisdiction, meaning the flight departed from an EU airport or was operated by an EU carrier arriving in the EU, and whether the disruption exceeded the thresholds that trigger compensation.

Once eligibility is confirmed, the calculator applies the fixed compensation tiers based on flight distance: €250 for flights up to 1,500 kilometres, €400 for flights between 1,500 and 3,500 kilometres, and €600 for longer journeys. It also factors in whether the delay exceeded three, four, or five hours depending on route length, and whether extraordinary circumstances such as severe weather or air traffic control strikes might reduce the airline's liability. Good calculators also account for connecting flights booked under a single reservation, calculating delay based on your final arrival time. This gives you a realistic estimate of what you could claim before submitting a formal claim to the airline.
Who Qualifies Under EU261
An EU261 claim eligibility calculator works by taking the key details of your flight and matching them against the rules of Regulation EC 261/2004. You typically enter your departure and arrival airports, the airline, the date of travel, and what went wrong, whether that was a delay of three hours or more at arrival, a cancellation with short notice, or denied boarding due to overbooking. The calculator then determines whether the route falls under EU261 jurisdiction, which covers flights departing from any EU or UK airport regardless of the airline's nationality, as well as flights arriving in the EU or UK when operated by an EU or UK carrier. It also checks the distance of the route, since compensation tiers are set at 250, 400, and 600 euros depending on how far you flew.
Beyond eligibility, most calculators estimate the payout amount you could expect, adjusting for circumstances such as extraordinary events like severe weather or air traffic control strikes, which airlines can use as a defence. The tool gives you a quick, free indication of whether a claim is worth pursuing before you engage a claims company or take the matter further.
Using the Eligibility Calculator
An EU261 claim eligibility calculator determines your compensation by first checking whether your flight falls under the regulation's scope. You enter your departure and arrival airports, the airline, and the flight date, and the tool verifies if the journey touches the EU or UK or is operated by a community carrier. It then compares the delay on arrival against the three-hour threshold, or identifies cancellations and denied boarding, while factoring in extraordinary circumstances such as severe weather or air traffic control strikes that can exempt the airline.
The calculator also measures the great-circle distance between your origin and destination to assign the correct compensation tier, typically €250, €400, or €600, and checks whether the disruption occurred within the last six years for UK claims or the relevant limitation period elsewhere. At aiflightrefunds.com, the AI Flight Refunds tool applies these EU261 and UK261 rules automatically, so you receive an instant estimate of what you are owed without manually interpreting the legislation.
Extraordinary Circumstances Explained
An EU261 claim eligibility calculator works by taking the basic facts of your flight and applying the rules of Regulation 261/2004 automatically. You typically enter your departure and arrival airports, the flight distance, the length of the delay or the nature of the disruption, and whether the airline notified you in advance of a cancellation. The calculator then determines which compensation band applies: €250 for short flights up to 1,500 kilometres, €400 for medium flights between 1,500 and 3,500 kilometres, and €600 for long-haul flights beyond that threshold. If your delay was reduced to under three hours on arrival, or your rebooking got you close to the original schedule, the tool may halve the amount.
The calculator also screens for the factors that can invalidate a claim. It checks whether extraordinary circumstances such as severe weather, air traffic control strikes, or security threats might excuse the airline, and whether the flight departed from an EU airport on an EU carrier, since that determines jurisdiction. By combining distance bands, delay thresholds, and exemption rules, the calculator gives you a realistic estimate of what you are owed before you submit a formal claim.
Filing Your Claim Step by Step
An EU261 claim eligibility calculator works by taking the basic details of your flight and matching them against the rules set out in Regulation EC 261/2004. You typically enter your departure and arrival airports, the flight date, the airline, and the length of the delay or the fact that the flight was cancelled. The calculator then applies the distance bands that determine payout levels: 250 euros for flights up to 1,500 kilometres, 400 euros for flights within the EU over 1,500 kilometres or other flights between 1,500 and 3,500 kilometres, and 600 euros for all other flights. It also checks whether the delay at your final destination exceeded the thresholds of three, four, or five hours that apply to each distance band.
Beyond distance and delay, a good calculator factors in the circumstances of the disruption. Compensation is only owed when the airline is responsible, so the tool may ask about reasons given for the delay or cancellation, such as weather, air traffic control strikes, or mechanical faults. Extraordinary circumstances generally disqualify a claim, while technical problems usually do not. The calculator also considers the airline's nationality and route, since EU261 covers flights departing from EU airports on any carrier and flights arriving in the EU on EU-based airlines. Some tools additionally apply the UK261 rules for flights touching the United Kingdom. The result is an estimate of what you may be owed, which AI Flight Refunds can then pursue on your behalf.
