What is a key component of the O'Hare Airport's security plan?

A key component of O'Hare Airport's security plan involves access control for sensitive areas through badge management. This is crucial because it ensures that only authorized personnel have access to secure zones within the airport, thereby maintaining the safety and security of both passengers and staff. Badge management systems typically include the issuance of identification badges that are monitored and regulated, which helps to prevent unauthorized access and potential security threats.

Ensuring tight security measures through access control is particularly important in busy transportation hubs like airports, where there are numerous sensitive areas, such as baggage handling, flight operations, and security checkpoints. By implementing a robust badge management system, O'Hare can effectively manage who enters these critical areas and when, enhancing overall airport security.

The other options relate to airport operations and customer service but do not address the essential security measures required to safeguard sensitive areas. Frequent traveler discounts, increased advertising, and streamlined check-in procedures are more about enhancing customer experience and operational efficiency rather than focusing directly on security protocols.
