In Belgium, smoking is prohibited in public buildings - including airports - except in specially equipped smoking rooms. This ban also applies to electronic cigarettes.
Please have a smoke outside if possible. On both the departures and arrivals level, smoking areas are provided at the entrances and exits of the building.
Within the building, there are currently 3 smoking areas available after security screening: in Pier A near gate A30 and A/T 65-67, as well as in gates B near gate B17.
