I went through security this afternoon around 4 pm at the D Gates. I am happy to report that the lines were not long at all, we breezed right through. One interesting note: they were strictly enforcing the 1 carry-on plus 1 presonal item rule. The area leading up to the lines was littered with people trying to jam their extra bags into their carry-on. I actually saw a woman get sent back to the check-in area to check her 2 extra shopping bags.
