It's been awhile since I've flown into the US so I'm not sure if the policy is the same as it used to be, where you HAD to take the laptop out of the sleeve and let it get banged around in the gray bin by itself. If you have a sleeve with no zippers on it, is it ok to leave the laptop inside the sleeve, otherwise alone in a gray bin? Or do we still have to take them out? I'm asking for both Japan and America. Thanks.
