I've also used the services of the infamous CAI touts to get ahead of the lines at security. They have relationships with staff that makes it seem "official" when, of course, we know it is not. For 50-100 EGP ($3-$6 USD), they allow me to circumvent certain protocols, even without having a BP in hand. They will use the business class or Gold Track lanes, even if you do not qualify to use them. Just make sure not to let them see them a wad of bills, as their eyes will dictate how much they can cajole out of you.
