Which passengers must receive an individual briefing from the flight attendant?

The correct answer highlights the importance of ensuring that passengers with disabilities receive individual briefings from the flight attendant. This is crucial because passengers with disabilities may require specific assistance or have special needs regarding safety procedures, evacuation routes, or the use of safety equipment. Individual briefings allow flight attendants to tailor the information to the specific needs of these passengers, thereby enhancing their safety and comfort during the flight.

Providing specialized attention ensures that all necessary details are clearly communicated, which may not be fully comprehended in a general briefing. This extra care is integral to complying with regulations and fostering an inclusive travel environment for everyone.

In contrast, other options such as briefing all passengers or only selected groups like first-class passengers or children do not take into account the unique considerations that need to be provided to those with disabilities. General briefings may not effectively address the specific concerns and requirements of these passengers, making the individual briefing the best practice in promoting their safety.
