Which of the following is NOT a function of cabin announcements?

Cabin announcements serve several critical functions that enhance passenger experience and safety during a flight. One of the primary purposes is to convey safety instructions, ensuring that all passengers are aware of emergency procedures and the proper use of safety equipment. Additionally, providing updates about food service is essential for keeping passengers informed about when they can expect meals or snacks, thus managing their expectations and enhancing overall comfort on board. Sharing flight path information is another vital aspect, as it allows passengers to understand the status and progress of their flight, which can contribute to their overall satisfaction and provide a sense of reassurance.

Given the context of these functions, promoting flight crew friendships does not align with the core purposes of cabin announcements. Such an endeavor does not contribute to safety, comfort, or the informative aspect that passengers rely on during their journey. Therefore, this choice stands out as it does not fulfill the role expected from cabin announcements in a flight setting.
