What is the first step for a SkyWest flight attendant to access the airport sterile area using the KCM access portal?

The correct choice details the procedure for a SkyWest flight attendant to gain entry into the airport sterile area by utilizing the Known Crew Member (KCM) access portal. It is essential for the attendant to swipe the KCM barcode tag across the checkpoint scanner because this action allows the system to verify their identity efficiently and confirm that they are authorized individuals who meet the necessary security requirements.

This process streamlines the entry for crew members, as the KCM program is specifically designed to expedite access for vetted airline personnel by utilizing advanced scanning technology. The swiping action captures data linked to their pre-approved status, allowing for a quicker transit through security compared to standard passenger checks.

In summary, swiping the KCM barcode tag is the initial and crucial step in the procedure for accessing the sterile area, as it authenticates the flight attendant's credentials for airport entry.
