If the incident occurred in another EU country
If your delay, cancellation or denied boarding occurred in another EU country, you must file a complaint with the competent authority in the EU country where the incident occurred.
If the incident occurred in a non-EU country on a trip to an EU country with an EU-registered air carrier, you must file a complaint with the authority in the EU country of arrival.

Danish Civil Aviation and Railway Authority case handling
The the Danish Civil Aviation and Railway Authority will process your complaint free of charge within 3-6 months. However, there is currently a large number of complaints which can lead to protracted case handling times.
During the handling of your complaint a need for further information or documentation from you or from the air carrier may arise.
If your complaint is upheld by the Danish Civil Aviation and Railway Authority, the air carrier must pay compensation and/or a refund within four weeks. If you do not receive a refund and/or compensation from the air carrier within those four weeks, you can contact the Danish Civil Aviation and Railway Authority who will then send a payment reminder to the air carrier.
If the air carrier still fails to pay a refund and/or compensation, the Danish Civil Aviation and Railway Authority will send the complaint to the prosecution service.
If the parties disagree with the Danish Civil Aviation and Railway Authority's decision, they may present the case before the national courts.
