What purpose do seatbelt extenders serve?

Seatbelt extenders are specifically designed to accommodate passengers who may require additional length to properly secure their seatbelts. This includes individuals with larger body sizes, ensuring that they can fasten and secure themselves safely during a flight. The extenders help ensure that all passengers, regardless of body size, can comply with safety regulations, promoting their safety and the overall safety of the flight.

While other options may mention related concepts, they do not accurately define the primary function of seatbelt extenders. They are not used to add cushioning for comfort, extend seatbelts for taller passengers, or support luggage, which are all separate aspects of flight safety and comfort. The focused purpose of allowing secure fastening for passengers of size and child restraint systems clearly outlines the critical role of seatbelt extenders in enhancing passenger safety.
