Procedure to submit a complaint to AESA. Regulation No.261/2004

    NOTICE: The deadlines for the resolution of claims are being delayed due to the high number of complaints received at AESA as a result of several incidents with particular impact on flight delays and cancellations. AESA is working to restore the usual processing times.

Action in AESA and deadlines

    After filing a complaint with AESA, the Agency will review whether there was a breach of Passenger Rights Regulation (EC) 261/2004 and will request the airline information on the facts, collecting the necessary additional information and examining whether or not the airline complied with the provisions of that Regulation.

    After the examination of it, AESA will send the applicant and airline, within 90 days (or 120 days in certain cases) as from the receipt of the complaint, a report highlighting what his/her rights are and, where appropriate, the necessary instruments so that they can be restored.

    In the event that AESA report is favorable for the passenger but it is not complied by the airline, the only option would be to go to court and in that event the AESA favorable report will be very useful



Complaint to the Airline

    The first step before you can file a complaint with AESA is to file a complaint with the airline responsible for the incident.

    You can do this through the complaints sheets that are usually available at airline information desks or ticket sale points at airports or by using the form below to file a complaint with an airline/airport manager.
    The complaint should be addressed directly to the airline customer service department, either by letter or by electronic means if available. List of Airline Customer Services.

    The ticket, baggage check and other documents used should be kept. In addition, the complaint should be clear, concise and legible. It is important to accurately record the date, time, place and causes of the complaint as well as the personal data of the complainant and of his/her flight.

    As soon as you receive a response from the airline, you may file a complaint with AESA, if the airline response does not satisfy you.

    After a month without receiving a response from the airline, you may file a complaint with AESA.
    You should keep a copy of the complaint filed with the airline in addition to the response, if any, and the correspondence with the airline in order to file the complaint with AESA.


Complaint to AESA

    After receiving the response to the complaint filed with the airline or after one month without obtaining a response from the airline, you may initiate the formalities to file the complaint with AESA.

    You can file a complaint with AESA free of charge. There are two ways to file the complaint (only one of the two ways will be accepted):

    Any other documents of interest:

    • Copy of the invoices of meals and refreshments invoices consumed at the place where the incident occurred (airport of origin).

    • Copies of the phone call invoices made or emails sent from the location where the incident occurred (airport of origin) 
    • Copy of the ticket if you purchased an alternative transportation on your own.


Courts of Justice

    If the solution offered by the airline does not fully satisfy you or the airline does not act in accordance with the provisions of the report issued by AESA, you may go to the courts of justice filing a claim against the airline to defend  your rights and request compensation by damages, if you consider it is convenient.

    In this regard, we inform you that AESA has no competence in the private contract of carriage and cannot submit complaints or exercise legal action against airlines, since there is no legal link between the carrier and the aeronautical authority.
