While overall airport security is managed by airport authorities and security agencies, the immediate responsibility for ensuring compliance with security protocols for the operations of a specific airline at a smaller airport typically lies with the Station Manager of the concerned airline.
The Station Manager is the senior representative of the airline at that location and is responsible for managing all aspects of the airline’s operations, including the implementation of security procedures for passengers, baggage, cargo, and aircraft specific to that airline, in coordination with airport security.
At larger airports, airlines might have dedicated security personnel. However, at smaller stations, this responsibility is often part of the Station Manager’s overall role, acting as the focal point for the airline’s security compliance and liaison with airport security forces like BCAS and CISF (Airport Security Group).
