NOTE: Whether one has PreCheck on one's boarding pass or not, I find using my Global Entry card as admitting identification to TSA CHEVK-in queues gets me the PreCheck queue, or where there isn't one (TBIT-T4 connector at TBIT side) they'll give me "PreCheck lite" (no shoes or belt off, no necessity of removing liquids and gels bag or laptop / tablet, variably).
