Anything larger than the current 757, turn times are not limited by number of aisles, pax, or doors, the turn time is limited by baggage and the ability to on/off load bags in the time allotted. More overhead bins will help but not solve the issue. Manual loading simply cannot keep up unless you go to a palletized system. Nesting cargo sections is only a partial solution.
