What type of information is typically NOT covered in a pre-flight briefing?

The type of information typically not covered in a pre-flight briefing is related to the flight crew's personal travel plans. Pre-flight briefings are designed to focus on critical operational information that directly affects the flight. This includes current and forecasted weather conditions, details about the destination airport, and emergency procedures that need to be understood and practiced by all crew members for safety and compliance with regulations.

Personal travel plans of the flight crew do not influence the safety or operation of the flight and therefore are not relevant to the pre-flight briefing. The emphasis during these briefings is on ensuring that all aspects that could impact the flight's safety and efficiency are clearly communicated and understood by the crew.
