Who has the authority to deny boarding to passengers?

The authority to deny boarding to passengers rests with the In-charge and/or the Pilot in Command (PIC). This is because the In-charge, typically the lead flight attendant, has responsibility for the safety and well-being of all passengers and crew on board the flight. The PIC also has final authority over all decisions related to the flight, including passenger management.

Denying boarding can be necessary for various reasons, including safety concerns, if a passenger is deemed unfit to fly, or if they are disruptive or pose a threat to other passengers or crew. In such situations, it is crucial that the designated personnel, who are trained and have legal authority, handle the situation appropriately to ensure the safety of everyone involved.

While other options might suggest different roles could have some influence in the process, only the In-charge and the PIC possess the definitive authority to make the boarding denial decision in a formal and accountable manner.
