It took forever to sign up. We were in a long TSA LINE AND WERE TOLD IT WOULD ONLY TAKE 3 MINUTES to sign up. By the time we FINALLY got through the sign up process and got to the TSA agent the people who were in front of us originally were way in front of us on there way to there gate. Once we got the approval, all it did was move us to another line waiting to stand in front of the TSA agent who reviewed all of our info anyway. I see little to no benefit for this service, especially not nearly $400 per year. Another total scam to skim money from anxious travelers.
