I recently paid the $78 to sign up for TSA PreCheck. I was going to get the Global, but didn’t have time before the trip.
I did not think it would really be that significant of a time difference. I spent about 2 minutes goin through security. Compared to the estimated 25-30 minutes for the “normal” people, I don’t want to be normal.
It also allows you to leave your electronics in the bag and keep your shoes on. Those alone are worth the price.
