What is a primary goal of screening passengers before a flight?

The primary goal of screening passengers before a flight is to prevent prohibited articles from being introduced into security-restricted areas. This is a critical aspect of aviation security, as it helps to ensure the safety of both passengers and crew on board the aircraft. Various items, such as weapons, explosives, or other dangerous materials, pose significant security risks and could potentially be used to harm individuals or compromise the safety of the flight.

Screening processes, which often include the use of metal detectors, X-ray machines, and personal searches, are designed to detect and eliminate these threats before passengers board the aircraft. By effectively identifying and confiscating prohibited items, security measures help create a safer flying environment.

Other options do not align with the fundamental purpose of passenger screening. Verifying ticket information and ensuring passengers have luggage may be operational procedures, but they do not directly contribute to enhancing security and preventing dangerous items from being brought onto an aircraft. Collecting additional fees for service is also unrelated to the essential safety objectives of the screening process.
