Well I’m not really knowledgeable enough to say exactly what had changed equipment wise and there was no change to the volume of liquids allowed as far as I could tell. But on Fast Track every passenger went through the body scanner and nothing had to be removed from hand luggage , bag in tray and off it went. I would say though the amount of bags waiting for secondary searches seemed higher than usual and they were not exactly getting them done quickly as far as I could tell.
