We don't fly much, but when we did a couple of years ago, my two bags, and my wifes two, had all of the zipties removed by TSA. But only one of mine had the notice that they usually (or so I have heard) place in a bag that they have opened. I did have my toenail clippers in my pocket (the deadly hooked end on the file part removed), and it passed thru the checkpoint without incident. My wifes underwire bra was another thing tho...
