What is the primary communication task during the final walk-through for flight attendants?

The primary communication task during the final walk-through for flight attendants is to conduct a passenger count. This critical step ensures that all guests who are supposed to be on the plane are accounted for before departure. Accurately knowing the number of passengers is vital for safety and compliance with regulations, as well as for the efficient management of in-flight services.

During this final check, flight attendants will also verify that passengers are settled in their seats, all carry-on luggage is properly stowed, and that there are no last-minute changes. This task helps identify any discrepancies in the count, which can be crucial in ensuring that all emergency procedures are executed correctly in case of an incident.

While the other options may be important aspects of the flight crew's duties, the passenger count is prioritized during the final walk-through because it directly relates to the safety and well-being of everyone on board.
