On our last trip to DW in December. I knew my carryon had at least one pair of kids type scissors in them. (ended up having two pairs; one of each bag) Those bags went through fine and they weren't even the blunt kind.
Now my 12yo DD gets her school backpack pulled for extra screening. We asked what was wrong with the bag so we could give them whatever they wanted and speed things up. They couldn't tell us and my daughter didn't remember having anything weird in the bag. Well here there is a small pocket on the inside of the bag (WAYY DOWN) that had her school scissors in it. She has a pair that were a little longer than the ones I had (they weren't even full size or hair scissor sized). But apparently they didn't want them on the plane in carryon. Since they were a cheap pair ($2-3) We just let them keep the scissors.
Strange standards.....
My DD got pulled for extra bag check on the way back from MCO too.... They just looked at everything (Took her brand new, still in box with reciept, because we bought it like 5 minutes prior to getting in line, SWATCH watch apart and everything.)
Next trip we're not letting her carry any bags through since she appears to look dangerous or something. Gotta watch those 12yo's.
