I've flown back on the red-eye on F9 to ATL and am 0-for-the-last-2 in it being manned at 10-10:15 p.m. Just not enough total pax these days, I s'pose, and not enough flights added back yet. There might be one or two booths open in the regular area, where they'll give you a card that usually gets you through the metal detector with shoes on rather than the L3 machine, but they still want you to separate electronics from the bag. Whereas in ATL if you have only one tablet or laptop you could leave that in the bag if Precheck.

As long as crowds have been really light (as evidenced by not having many flights on the departure screen) it hasn't been much of an inconvenience. I do remember pre-pandemic times when it was a MAJOR help to be able to use the PreCheck line because of what the regular line looked like.
