An overhead flow distribution assembly for an aircraft cabin, the assembly comprising: a conduit (16;18) defining a plenum having an inlet (24a;24b), upper outlets and lower outlets, the upper outlets spaced apart from each other along a longitudinal direction of the aircraft, the lower outlets spaced apart from each other along the longitudinal direction, the inlet (24a;24b) being located between the upper outlets and the lower outlets; and a baffle extending within the plenum along the longitudinal direction, the baffle being located between the upper outlets and at least part of the inlet (24a;24b) along a transverse direction normal to the longitudinal direction, the baffle having openings defined therethrough, the baffle configured to restrict airflow from the at least part of the inlet (24a;24b) toward the upper outlets, wherein the conduit comprises a first conduit and the plenum defined by it is a first plenum, the inlet defined by at least one opening through a wall of the first conduit, the wall extending along the longitudinal direction, the baffle extending within the first plenum being a first baffle located between the upper outlets and the inlet, the assembly further comprising: a second conduit extending adjacent the first conduit along the longitudinal direction, the second conduit defining a second plenum having a second inlet, second upper outlets and second lower outlets, the second upper outlets spaced apart from each other along the longitudinal direction, the second lower outlets spaced apart from each other along the longitudinal direction, the second inlet being located between the second upper outlets and the second lower outlets, the second inlet located in an end of the second conduit adjacent the first conduit and defining a fluid communication between the first plenum of the first conduit and the second plenum; and a second baffle extending along the longitudinal direction within the second plenum, the second baffle being located between the second upper outlets and at least part of the second inlet along the transverse direction, the second baffle having openings defined therethrough and being configured to restrict airflow from the second inlet toward the second upper outlets. a conduit (16;18) defining a plenum having an inlet (24a;24b), upper outlets and lower outlets, the upper outlets spaced apart from each other along a longitudinal direction of the aircraft, the lower outlets spaced apart from each other along the longitudinal direction, the inlet (24a;24b) being located between the upper outlets and the lower outlets;
