TSA Pre is not what it used to be. It used to offer two advantages: Less-invasive screening, and mostly frequent fliers in the line. Over the past year or so, the second advantage has evaporated in many large airports I've traveled through. The airlines seem to be handing out Pre chits like candy now, and the Pre line is full of little kids, baby strollers, and people who have never been on an airplane before. It still saves time, just not as much as in the early days.
