When a flight attendant determines that a passenger is unacceptable for carriage, who must they contact?

The flight attendant is responsible for assessing the safety and comfort of all passengers onboard. When they determine that a passenger is unacceptable for carriage due to safety concerns, disruptive behavior, or any other serious issues, it is imperative to involve the Pilot in Command. The Pilot in Command has the final authority and responsibility for the operation of the flight and the safety of everyone onboard.

By contacting the Pilot in Command, the flight attendant ensures that appropriate action can be taken based on established protocols. This may include making the decision to deny boarding or further assessing the situation in consultation with the flight crew. The authority of the Pilot in Command is essential in maintaining safety and ensuring that any potential risks are addressed adequately, aligning with industry standards and safety regulations.
