What is the designation for the AFT bench jump seat often referred to as a loveseat?

The designation for the AFT bench jump seat, commonly referred to as a loveseat, is associated specifically with the A320 Spaceflex and A321 NEO configurations. This bench seat is designed for accommodating additional crew members or jump seated personnel, enhancing passenger handling during specific flight operations.

The A320 Spaceflex is a unique layout that maximizes cabin space and flexibility, allowing for the inclusion of the loveseat configuration. The A321 NEO also supports this seating arrangement due to its design changes that accommodate more modern operational needs.

This understanding of the A320 Spaceflex and A321 NEO distinctions sheds light on how aircraft seating arrangements are tailored to fit both capacity and operational requirements. Other options either limit the applicability of this designation to just one model, or to configurations that do not incorporate the bench jump seat as standard, which is why they are less accurate.
