The expert lines were moving fairly quickly today. There was one "expert" who tried to fill the bolted down bin, but otherwise everyone knew the drill. Apparently they have started a new procedure for SSSS'ing someone. I was in line 3 and got SSSS-3 on my BP (no ID as usual). With the number designation, there was no writing down of extra BP info, the patdown was quick, they only gave my bag a cursory screen (they did open the main compartments but not the inner ones like they used to), my BP got a quick punch and I was on my way. 90 seconds of extra "trouble". Just wanted to share.
