If you believe that you have a valid complaint against an airline regarding denied boarding, downgrading, cancellation or long delay, you should first contact the air carrier that operated the flight. Regulation 261/2004 applies to all flights operated by any airline from any EU airport and flights to an EU airport operated by any EU airline. Below are suggestions of free contact points in case you need further assistance.
European Consumer Centre (ECC)
A European Consumer Centre (ECC) supported by the European Commission exists in every EU country as well as in Iceland and Norway. The centres are there to help travellers who have difficulties in having their rights respected, such as the right to be reimbursed or re-routed to the final destination and right to obtain meals and accommodation. Follow the link for full contact details for ECCs for all countries and links to national websites.
EU complaint form for air passengers
The form can be used to lodge a complaint with an airline and/or national enforcement body regarding air passenger rights in case of long delay, cancellation, denied boarding or downgrading under Regulation (EC) 261/2004.
The complaint form should be sent to the airline or competent National Enforcement Body, NOT to the European Commission.
National Enforcement Bodies
The EU rules oblige Member States to nominate or create “national enforcement bodies”, whose role is to verify that transport operators are treating all passengers in accordance with their rights. Passengers who believe they have not been treated correctly should contact the body in the country where the incident took place. Contact the National Enforcement Body for your specific mode of transport. You can find the lists here: Air | Rail | Maritime | Bus
