Flew out of IAD Thu 5/26 with a 7:45pm flight. Got there about 6:15 expecting the worst. There was no waiting in the regular TSA security stations whereas Pre Check had quite a few waiting to be serviced. Just my observation, YMMV.
My experience with TSA Pre-Check after shelling out the $65 and going in for the “interview.”
1. The first time I used it, I was randomly selected to go through the full line. Not allowed to use Pre even though my boarding pass was clearly marked.
2. The second time I used it, the line at Pre was longer than the regular line, so I chose the regular line. I’m always prepped to scoot through inspection quickly because I know the drill.
I’ve had two or three better experiences, but so far about 1/3 of my flights indicate it was a waste of money. Now this is personal travel these days as my business travel (mercifully) has gone close to zero the past decade.
