When IAD opened their new TSA screening area last year, initially there was mass confusion, and the priority lines were useless, thanks to TSA incompetence. Many UA FFs complained to the UA 1K and PE Voice mailboxes, and in short order the airport produced contract employees to marshal the lines and restore order.
