Airlines for America (A4A) and the Transportation Security Administration (TSA) continue to seek ways to improve the integrity and security of the Known Crewmember (KCM) Program. Effective March 31, 2022, the TSA will require KCM eligible crewmembers to scan a KCM-issued barcode card when utilizing a KCM access point. Crewmembers will no longer be permitted to manually enter their KCM data. Crewmembers who do not have a KCM barcode card, have a worn/unreadable barcode card, or have not completed the registration process will be referred to the passenger screening checkpoint for entry into the airport sterile area If a crewmember does not present an active KCM barcode card and is referred for screening, then they must follow the TSO’s instructions and complete the screening process at the passenger screening checkpoint. Failure to submit to screening at the passenger screening checkpoint (e.g., using a SIDA badge to avoid screening), is considered circumvention of screening and TSA may take enforcement action in accordance with the KCM Disqualification Protocols (KCMDP). Crewmembers may request a new or replacement KCM barcode card from their airline management.
