An aircraft seating assembly including a replaceable underseat passenger accommodation feature tray includes passenger seats incorporating in-flight entertainment (IFE) system components for the use of the occupying passengers or neighboring passengers in the seats immediately behind. The IFE system components are connected by internal cabling paths within the seating assembly to contact points, and seat electronic boxes (SEB) mounted to a replaceable passenger accommodation feature tray provide IFE services to the system components. The SEB is connected to a second set of contact points on the feature tray by cabling paths that circumvent the spreader and leg structures of the seating assembly. When the feature tray is fully mounted to the seating assembly, the SEB is connected to the IFE system components through the cabling paths and contact points at which the cabling paths terminate, each contact point on the feature tray having a counterpart in the seating assembly.
