An addition to the already-time-consuming passenger check-in process, a new security level has been installed at Syracuse Hancock International (SYR) and Atlantic City (ACY). If proven effective, it will soon be caging people at an airport near you.

They’re barred, glass-framed exit pods that hold individual passengers before they’re permitted to board flights. Security personnel guide them into the pods to be electronically body-scanned while recorded voices tell them to wait. Then a green light indicates the process is complete, and the cell-like pod door can be opened.
