3-1-1 issue with Clear 3D Packing Cube
Has anyone else had their clear 3D cube NOT allowed as a 3-1-1 bag? I've been very sternly told that the 3-1-1 must be in a quart size zip-lock bag - not larger (I can understand) and not smaller - (say what? are you joking?)! This has happened to me at my hometown airport, San Diego, as well as Albuquerque, and Chicago (Midway Airport). I now carry a quart size zip-lock bag to dump my 3D into if the TSA agent gets strict about it, but I am wondering if anyone else has had this problem?
ETA: it wasn't every time I flew out of these terminals, just once, so far, for each, and I know that the TSA agent has final say-so. My typical 3-1-1 is travel size shampoo, toothpaste and deodorant, my mascara and lip balm. Nothing out of the ordinary.
ETA: I meant 3D cube, not the CQPC.
