Passengers who qualify for compensation can start by filling out this online form. Anyone intending to claim compensation under Flight Compensation Regulation 261/2004 must have both their confirmation code and ticket number on hand. They should then take their claim directly to the airline where they might be instructed to fill out additional paperwork. If the airline fails to respond to the request within six weeks of receipt or if the passenger isn’t satisfied with the airline’s response, they can forward a copy of the form to the national enforcement body of the country where the incident took place.
Alternatively, passengers can contact one of the many companies specializing in Flight Compensation Regulation 261/2004 claim assistance like AirHelp, EUclaim, Flightright, or refund.me, but be aware that these companies do take a small cut out of the recovered funds.
Passengers who were given more than 14 days notice about an upcoming flight cancellation are only entitled to a new flight or a refund in the amount of their original flight and no additional compensation. However, those given less than 14 days notice about an upcoming flight cancellation might be able to claim compensation on top of their refund or replacement flight.
