## Understanding Eligibility Criteria For Claims

Determining the exact compensation amount for delayed flights under EU261 requires a precise calculation based on flight distance and the duration of the delay. The regulation defines three distinct tiers of compensation, which depend entirely on the total distance of the journey. For flights under 1,500 kilometers, passengers are entitled to a fixed sum of €250. If the flight distance falls between 1,500 and 3,500 kilometers, the compensation increases to €400. For all routes exceeding 3,500 kilometers, the maximum compensation stands at €600. Crucially, the delay must be at least three hours upon arrival at the final destination to qualify for any payout. Airlines are not required to pay compensation if the delay was caused by extraordinary circumstances beyond their control, such as severe weather or political instability.

To calculate your specific entitlement, you must first verify that the delay meets the minimum threshold and that the airline is responsible for the disruption. Once confirmed, apply the distance-based tier corresponding to your itinerary. It is important to note that these figures represent the standard compensation for the delay itself. They do not include reimbursement for additional expenses incurred, such as meals or accommodation, which may be claimed separately under different provisions. Always retain boarding passes and delay notifications as evidence. If the airline refuses payment, you can escalate the claim through national enforcement bodies or legal channels. This structured approach ensures you receive the full amount mandated by law without overcomplicating the process.

## Calculating Compensation Amounts By Distance

Under Regulation (EC) No 261/2004, the compensation amount for a qualifying delay is determined by the great-circle distance between your departure airport and your final destination, not by any connecting segment. Flights of 1,500 kilometers or less are eligible for €250. Intra-EU flights longer than 1,500 kilometers, and other flights between 1,500 and 3,500 kilometers, qualify for €400. Flights covering more than 3,500 kilometers fall into the highest tier at €600. This structure ensures passengers on longer journeys receive higher compensation regardless of ticket price or fare class.

A key detail is the reduction rule for long-haul delays. If your flight exceeds 3,500 kilometers and arrives at your final destination between three and four hours late, the airline may cut the €600 payment by 50%, reducing it to €300. For delays of four hours or more on these routes, the full €600 applies. Arrival time is measured when at least one aircraft door opens, allowing passengers to disembark. At AI Flight Refunds, we apply this distance and timing framework to calculate the exact amount you may be owed.

## Determining Airline Liability And Exceptions

Once liability is established, calculating the payout under EU261 depends primarily on flight distance rather than the ticket price or the length of the delay itself. Flights of 1,500 kilometres or less qualify for €250, flights between 1,500 and 3,500 kilometres, plus all other flights over 1,500 kilometres operated by EU carriers, qualify for €400, and flights exceeding 3,500 kilometres qualify for €600. The delay must exceed the relevant threshold—three hours for short flights, four hours for medium routes, and four hours for long-haul—to trigger the payment, and this is measured against arrival at the final destination, not departure time.

One important adjustment applies to long-haul flights: if the delay is between three and four hours on a journey over 3,500 kilometres, the compensation is halved to €300. Passengers should also confirm the airline was responsible for the disruption, since extraordinary circumstances such as severe weather or air traffic control strikes exempt carriers from payment entirely. Keeping boarding passes and arrival records makes the calculation straightforward when submitting a claim.

## Navigating The Submission Process Steps

For a valid claim, calculate the delay at the final destination, not at each connection. Use the great-circle distance between the first departure airport and the final arrival airport, then apply the fixed bands: EUR 250 for flights up to 1,500 km; EUR 400 for intra-EU flights over 1,500 km and other flights between 1,500 and 3,500 km; EUR 600 for all other flights over 3,500 km. If arrival is more than three hours late, the route and distance band set the amount.

The practical ambiguity is connecting itineraries: a missed connection counts if the same booking reaches the final destination three hours or more late, even when each separate leg is shorter. Extraordinary circumstances can remove the obligation, and the 50% reduction applies only when a re-routing offer gets the passenger to the final destination within the specified time margins. AI Flight Refunds can review the booking, distance, and delay evidence before submission.

## Handling Rejected Claims And Appeals

When an airline rejects your EU261 claim, the first step is understanding why. Common rejection reasons include claims of extraordinary circumstances, such as severe weather, air traffic control strikes, or security threats, which exempt carriers from paying compensation. Airlines also sometimes argue that delays fell below the three-hour threshold at arrival, or that the flight operated outside EU261's scope. Request the rejection in writing and scrutinise the evidence provided, since carriers frequently cite extraordinary circumstances without substantiating them. If you believe the refusal is unjustified, respond with your own documentation, including boarding passes, arrival records, and any statements from crew or airport staff.

The calculation of compensation for delayed flights follows a distance-based scale set out in the regulation. Flights of 1,500 kilometres or less qualify for €250, flights between 1,500 and 3,500 kilometres qualify for €400, and flights over 3,500 kilometres qualify for €600. Crucially, the distance is measured as the crow flies between departure and arrival airports, not the actual flight path. For delays exceeding three hours on arrival, the full amount applies, though airlines can reduce long-haul compensation by half if the delay is kept under four hours.

## Compensation Rates By Flight Distance

| Distance Category | Compensation Amount | Eligibility Condition | Claim Process |
| --- | --- | --- | --- |
| Under 1,500 km | €250 | Delay > 2 hours | Submit via airline portal |
| 1,500–3,500 km | €400 | Delay > 3 hours | Online form or email |
| Over 3,500 km | €600 | Delay > 4 hours | Legal assistance recommended |

Understanding EU261 compensation requires knowing that delays must exceed specific time thresholds based on flight distance. Airlines owe passengers fixed sums if the delay causes significant inconvenience. Always retain boarding passes and ticket details. If the airline refuses payment, consider using specialized refund services or legal aid to enforce your rights effectively under current regulations.

## Quick answers

### Does the airline owe me compensation if the delay was caused by weather?

No, compensation is not owed if the delay resulted from extraordinary circumstances beyond the airline's control.

### How long do I have to file a claim under EU261 regulations?

The time limit varies by country but is typically between two and three years from the flight date.

### Can I claim compensation if my flight was delayed less than three hours?

No, you are only eligible for compensation if the arrival delay is at least three hours.

### Do I need to prove financial loss to receive the standard compensation?

No, the compensation is a fixed penalty based on distance and does not require proof of specific financial loss.
