you don't have to take it out if you have precheck
I often travel in dumpy airports that don't have dedicated precheck lines.
like, the grand island, ne airport that only allegient serves has TSA Pre.
Newark Terminal A - have to wait in line with the other rubes, but they give you a card so you don't have to take off your belt/jacket/etc. Still have to take liquids/laptop out.
KCI Terminal C. Same as above but no card, just a green marker on your boarding pass. Sometimes they only do one line too, which sucks.
La Guardia - Same as above, but only once.
