TSA Safety / Security
​The Public Safety Office is responsible for airport security. A state of the art computer driven access
control system combined with both scheduled and un-scheduled airport patrols ensures the highest level
of security maintenance.

TSA Screening

The Transportation Security Administration (TSA) recently completed modifications to the passenger
screening point that brings new trace detection technology to MidAmerica St. Louis Airport. Improved
passenger safety is the mandate from Congress and MidAmerica St. Louis Airport, with the TSA, is
ready to go!
