I just used Touchless Pre for the first time and it was awesome, way more efficient and faster than CLEAR. One quick photo by one agent and that was it, no getting passed between CLEAR agents and still getting another photo by a TSA agent at the end. Didn’t even have to whip out the boarding pass except when entering the line. But I suppose it’s fast because it’s not used widely yet. You just have to pay attention that there are two TSA Pre lines now but the person at the entrance told me where to go after showing my boarding pass.
