The Allegiant Air Los Angeles Office provides information about airport security policies as well as what is and isn't allowed in an airport, prior to departure. You must present a valid form of identification and a confirmed boarding pass to go through security screening in the airport. Everyone's bags have to be checked and they are subject to restrictions on what is not permitted on the plane. Liquids, aerosols and gels must adhere to the applicable airport security restrictions. Electronic devices may require separate screening also. Arrive early to go through security without rushing.
