What should you do if you see someone who does not display a SIDA badge?

The appropriate action when encountering someone without a SIDA (Security Identification Display Area) badge is to report the situation. SIDA badges are implemented to ensure that individuals in secure areas of an airport have gone through proper vetting and have legitimate reasons to be there. By reporting someone who lacks a badge, you help maintain security and safety at the airport. This action allows trained personnel to follow up on the situation, potentially preventing unauthorized access to sensitive areas that could pose a security risk.

While challenging someone may seem proactive, it might not be safe or effective if you're not trained to handle such situations. Escorting someone who isn't authorized can also lead to security breaches, and ignoring the situation can put everyone at risk. Therefore, reporting is the most responsible and effective response.
