I’ve brought a large size bottle along for ride since 9/20. Handy to refill the small ones that we attach to bags, pant loops etc
I keep it in a zip bag in outside pocket of book bag. The process is easy enough. remove it from your bag, place in the dish & alert TSA to it
they will match it up with you on other side
& take it over to their machine to check it. You just follow the agent to that area
Whole process normally has taken just a couple of extra minutes. well, except for trip a month ago
A group of three, 20-somethings traveling together, just ahead of me in line, each had bottles of water, oversized hair products, sun screen spray, perfume bottles, etc

packed inside their zipped carryons. This was in precheck line BTW
They found it all quite amusing. One of them pulled out her camera to film her companion who was starting to walk around the plexiglass, attempting to grab something, before being sternly warned to step back.

I had visions of missing our flight. So happy to finally board our flight home and that they weren’t on it
