We both have Precheck clearance. The lane at ATL is nearly empty when we arrive--usually there are people who think they can use it but get sent back out. The ATL employee lanes have been nuts some days. We use the trusted traveler global entry number on our listing [once] and it's printed as Precheck in the upper left corner of seat request. I can guess we've saved 20-30 hours each by having both, coming and going. Sending you a PM.
