For EU flight delay, cancellation and denied boarding claims the correct Belgian escalation body is the FPS Mobility and Transport (Federal Public Service Mobility) air passenger rights team, the designated national enforcement body. The general Consumer Mediation Service (Service de Mediation pour le Consommateur) can also handle broader consumer disputes.

Complain to Brussels Airlines first and ask for a written final response. If they reject you or the deadline passes, you can take it to the FPS Mobility and Transport, Air Passenger Rights service (the Belgian national enforcement body for EU air passenger rights, Regulation EC 261/2004) for free, and their decision is binding on the company.
