As far as I'm aware (already searched this forum by the way), the laptop has to be removed out of the bag at the security check?. Question is, would it have to be taken out of a sleeve? I'm just concerned about it getting scratched dented etc. TSA (that's the American one) was fine with sleeve types, but that was because TSA explicitly allowed it. I'm considering getting a extra large ziploc bag just in case. Thanks in advance.
