The calculator shows how much compensation you can get under Regulation (EC) No 261/2004 for a delayed flight, cancelled flight, denied boarding or missed connection. Compensation is €250, €400 or €600 per passenger and depends on the flight distance, not on the ticket price. In certain cases, the amount may be reduced by half.

In short:

  • €250 - flights of up to 1,500 km.
  • €400 - flights between 1,500 and 3,500 km, as well as all flights within the EU over 1,500 km.
  • €600 - flights over 3,500 km outside the EU.
  • Distance is measured by the great circle route method to the final destination, as the Regulation requires. For connecting flights on one booking, the distance is calculated between the start and end points of the journey.
  • Compensation is due to each passenger individually. For four passengers on a flight between 1,500 and 3,500 km, the total is €1,600.
  • You can claim compensation if you arrive 3 or more hours late, if your flight is cancelled and you were informed less than 14 days in advance, unless you were offered an alternative flight with similar times, if you are denied boarding, and if you miss a connection and arrive at your final destination 3 or more hours late.

How to use the calculator?

All you need is the departure and arrival airports of the disrupted flight, or the flight number and date, and the number of passengers. The calculation takes less than a minute.

  1. Select the departure and arrival airports of the disrupted flight. If you don't have the details at hand, you can search by flight number or scan your boarding pass.
  2. Enter the number of passengers you want to check compensation for.
  3. The calculator will highlight the amount that matches the flight distance and show the total compensation for all passengers.
  4. Click "Check compensation now". The airports are transferred automatically to the registration form, where you fill in the remaining details of your trip.

The amount is indicative. For connecting flights on one booking, compensation is calculated for the whole route to the final destination, so it may be higher than shown. Whether compensation is due depends on the cause of the flight disruption. We check every case free of charge before we submit a claim to the airline.

The airline can be released from the obligation to pay compensation only if it proves extraordinary circumstances, such as bad weather or an air traffic control strike. A technical problem with the aircraft is, as a rule, not such a circumstance. See when you can claim compensation for a delayed flight and a cancelled flight, and what to do if the airline has refused to pay.

Compensation calculation examples

Compensation for the same route is always the same, regardless of the airline and the ticket price. Here is how much it is on some of the most common flights from Bulgaria:

Route Distance Per passenger For 2 passengers For 4 passengers
Sofia - Rome ≈ 930 km €250 €500 €1,000
Sofia - Munich ≈ 1,100 km €250 €500 €1,000
Varna - Dortmund ≈ 1,770 km €400 €800 €1,600
Sofia - London (Luton) ≈ 2,050 km €400 €800 €1,600
Sofia - Madrid ≈ 2,250 km €400 €800 €1,600
Varna - Tenerife ≈ 4,300 km €400 €800 €1,600
Sofia - New York ≈ 7,600 km €600 €1,200 €2,400

Varna - Tenerife is over 3,500 km, but the compensation is €400, not €600. The Canary Islands are part of the EU, and for flights within the EU over 1,500 km the amount is €400.

The amounts apply to flights departing from the EU. On return flights from a non-EU country, for example from London or New York to Sofia, compensation under the Regulation is due only if the flight is operated by an EU airline. Other laws may also apply to these flights - for example, the UK rules (UK261) for a flight from London.

How is compensation calculated for a connecting flight?

For connecting flights on one booking, compensation is calculated based on the direct distance from the first departure airport to the final destination. It is not based only on the distance of the flight that was delayed or cancelled, and the distances of the individual flights are not added up (judgment of the Court of Justice of the EU in case C-559/16).

Example: you fly Sofia → Munich → Madrid on one booking. The flight to Munich is delayed, you miss your connection and arrive in Madrid 4 hours late. The compensation is €400 per passenger, because the distance Sofia - Madrid is about 2,250 km. If only the Sofia - Munich flight (about 1,100 km) were taken into account, the amount would be €250.

The delay is also measured at the final destination. If the first flight is 2 hours late, but because of the missed connection you arrive at your final destination 3 or more hours late, you can claim compensation (judgment of the Court of Justice of the EU in case C-11/11).

This also applies when the connection is at an airport outside the EU, if the journey starts at an airport in the EU (judgment of the Court of Justice of the EU in case C-537/17).

If the flights were bought on separate bookings, each flight is assessed separately. In that case, compensation is calculated only for the flight that was delayed or cancelled. Read more about your rights in case of a missed connection.

When can compensation be reduced by half?

The airline can reduce compensation by 50% in two cases: when, in case of a cancellation or denied boarding, it offers you an alternative flight that gets you to your destination slightly later than originally scheduled, and when a flight of over 3,500 km outside the EU arrives 3 to 4 hours late. The calculator shows the full amount, without the reduction.

Distance Full compensation Reduced by 50% When it can be reduced
up to 1,500 km €250 €125 alternative flight arriving up to 2 hours after the original time
between 1,500 and 3,500 km and flights within the EU over 1,500 km €400 €200 alternative flight arriving up to 3 hours after the original time
over 3,500 km outside the EU €600 €300 alternative flight arriving up to 4 hours after the original time, or arrival delay of 3 to 4 hours

The reduction is not automatic. The airline has to apply it and prove that the conditions are met.

How does the process of collecting your compensation work?

1

You register a claim


You enter the flight details and provide the necessary documents.
2

Aeroisk takes on your case


We contact the airline and pursue the claim on your behalf. If it refuses to pay, we take the necessary administrative and legal action.
3

You receive up to €600 in compensation


If successful, the airline pays the compensation. A commission is only due if you receive compensation.

You can follow the progress of your claim in your personal account, and we email you whenever there is a change in your case. If you have any questions, you can always contact us by phone too.

Did the airline refuse to pay you?

The airline’s refusal does not necessarily mean that you are not entitled to compensation. The reason given in the refusal is not always sufficient to release the airline from liability.

Frequently Asked Questions

Why does the calculator show €600 when I may get €300?

The calculator shows the full compensation based on distance. For flights over 3,500 km outside the EU, the airline can reduce it by half if you arrive 3 to 4 hours late or if it offered you an alternative flight that gets you there up to 4 hours after the original time. In that case, the amount is €300.

Can I get compensation for a connecting flight?

Yes, if the flights are on one booking and you arrive at your final destination 3 or more hours late. Compensation is calculated based on the direct distance from the first airport to the final destination, so it may be higher than for the delayed flight alone. With separate bookings, each flight is assessed separately.

Is compensation paid for each passenger, including children?

Yes, compensation is due to each passenger individually, including children with a paid ticket. Passengers travelling free of charge or at a reduced fare not available to the public are not entitled to compensation under the Regulation. Tickets paid with loyalty programme points are included.

Does compensation depend on the ticket price or the airline?

No. The amount of compensation depends only on the flight distance and is the same for all airlines, classes and ticket prices. A passenger with a €30 ticket and a passenger with a €300 ticket on the same flight are entitled to the same amount.

How much does the Aeroisk service cost?

Checking your case is free. You pay a fee only if you receive compensation, and if we don't succeed, you owe nothing. Our fee does not increase if court or administrative action is needed.
