Not that I'm telling you guys how to do your jobs, but something that I've seen, as a passenger, is the frustration that passengers aren't well informed of what can go through security and what cannot go through security, and that makes things a lot slower. In the NEXUS line, for example, having to tell passengers to take their laptop out of their carry-on. They should know that before they even get their NEXUS pass. People should be able to do a test on something like that. Why would they be given a NEXUS pass if they don't know the basics of trying to get through security in the first place? In international airports I've seen all over the airport virtual 3-D individuals saying things like “This is what you have to do before you go through security” before people even get into the security line, whereas we don't have that. Even while we're waiting in the lines in security, nobody's challenging passengers to take away their liquids, make sure they don't have anything over 100 millilitres, make sure their laptop's in a different bin, make sure to take off their shoes, etc. That would actually make it more efficient once people got to the line, as opposed to going to the line and having the person walk through the metal detector three times.
