I have pre-check, which means I get to keep belt, shoes, and jacket on. Except one random time when this butthead TSA agent insisted I remove my jacket. I fought him on it, but he was an arrogant guy. Read your own rules dumb, dumb.
Also, they obsess over my bottle of contact solution regularly — wipe it down for bomb residue and everything, even though it is allowed. But, somehow I’ve accidentally slipped through with pocket knives and zippo lighters that were at the bottom of my bag. But, don’t you dare forget to empty your water bottle.
I use the same laptop bag for several trips a year, so I often don’t clear out all the pockets. The other day I realized I’ve been flying back and forth with a lighter I got from Vegas 2 years ago because it was buried at the bottom of a pocket. As for why the hell I had it in my laptop bag in the first place, I have no idea.
Zippos only if they’re empty. Who had empty zippos without lighter fluid?
The phrasing on the TSA website suggests that lighters with fluid are permitted in your carry on, just not your checked. This is also in line with the policy in Canada.
Whether the particular TSA agent you’re stuck dealing with actually knows their guidelines, well… don’t hold your breath, they also get pissy about frozen water bottles (which also are allowed).
I just don’t bother taking out small bottles of liquid for the last quite a few years and no one has cared or even noticed
