What type of security checks might a passenger undergo at the gate?

Passengers may undergo additional screening or identification checks at the gate to ensure the safety and security of the flight. These checks can include verifying boarding passes, matching passenger names with their identification documents, and conducting random checks for any prohibited items. This process is critical as it helps to identify any potential security threats and ensure that only authorized individuals are boarding the aircraft.

The other options present scenarios that are less common or unnecessary for gate security. Random drug testing, for instance, is typically not performed at the gate for regular passengers; it’s more likely reserved for specific groups of personnel. Passenger interviews are not standard practices at gate check-in and usually occur in different contexts, such as during initial screening at the airport. Finally, stating that no checks are performed at the gate would undermine the security protocols in place, which are designed to ensure passenger and flight safety.
