For those of you who don't know what this is, it takes you back to a point in airport security when you didn't have to do things like remove every piece of paper from your pants, or take off your belt or shoes. It's a wonderful thing. In previous trips, there wasn't a designated lane. You had to wait in the big line, then hopefully get the right beep when TSA scanned your boarding pass, and then they sent you along to a specific scanner checkpoint. Anyway, ffwd to the return trip through LAS. I ask the first TSA person I see if they have a pre-check lane, and she rolls her eyes and says no. When I got to the front of the line (which did move pretty quickly, as I thought they always did in T1), I got the triple beep after they scanned my BP which means that you're pre-check eligible for that particular flight. The TSA person there suggested that if I didn't have any luggage, it might be better for me to get dropped off in T1, clear security there (with the pre-check lane), and then take the shuttle over to T3. To me, that seems insane. Anyone know why they wouldn't plan for something like this when building a brand new "state of the art" airport? It's not like it requires complex infrastructure (it's just one additional line entrance point).
