In the event of a cancellation, long delay or denied boarding, it is recommended that you take your complaint first and foremost to the air carrier.
In the event that you do not receive a satisfactory resolution of your complaint from the air carrier, you can refer the issue to the attention of the relevant competent National Enforcement Body (NEB). Each member state has designated such a NEB, which is located in the respective country (as well as Iceland, Norway and Switzerland). Complaints should be sent to the authority in whose territory the incident occurred (the country from whose airport the flight should have started): Community National Enforcement Bodies (NEB).
