Was offered a free trial on a recent trip for me and my 9 year old son. I figured I’d give it a try as the line was pretty long. Got in the short Clear line and stood there while the couple of Clear reps dealt with the 3 or 4 people in front of me. Eventually I saw people in the regular line who were behind me go through and we were still in the clear line. Totally inefficient and did not save us time, we lost time. I opted out of the trial period less than 20 minutes of signing up.
