What is one method to verify the passenger manifest?

Performing a headcount is an effective method to verify the passenger manifest because it directly compares the number of individuals present on the aircraft with the list of passengers scheduled for the flight. This physical count helps to ensure that all passengers listed on the manifest have boarded the aircraft, and it can also identify any discrepancies, such as missing individuals or unaccounted-for passengers.

By conducting a headcount, aircrew can enhance safety and ensure compliance with regulations, as knowing the exact number of passengers is crucial in maintaining operational integrity during the flight.

In contrast, checking departure schedules provides information about the flight timetable but does not confirm the actual passengers aboard. Reviewing flight logbooks provides historical data about flight operations but does not verify current passenger presence. Contacting passenger service representatives can provide support and additional information but lacks the immediacy and direct verification that a headcount accomplishes.
