An aircraft cabin segment includes at least one longitudinally extending aisle, seats disposed in rows, at least two assemblies of baggage compartments, and ventilation outlets. The seats disposed in rows are transversal relative to the longitudinal aisle. The at least two assemblies of baggage compartments are aligned and positioned overhead. The baggage compartments of each of the two assemblies are aligned in a transversal direction and are positioned above the seats such that bottom surfaces of the baggage compartments form a sinusoidal wave along a longitudinal direction of the aircraft cabin segment. The ventilation outlets are disposed between the two assemblies of the baggage compartments.
