Everywhere we travel we bring a can of Lysol with us and spray the entire room upon arrival and several times during the week (past experience with Norovirus). We usually pack it in the checked bags, then have to wait for bags to be delivered to spray the room. We are flying in the night before and wondering if I can take it out of my checked back and carry it onboard on my carry on. Will this be a problem getting the aerosol can through security at the port? I wouldn't think so, but just want to make sure. FYI for those germ a phobes, we also carry travel packs of disinfectant wipes onto the plane and wipe down seats, armrests, pull down trays etc before we sit. We get a lot of strange looks, but have yet to get sick since starting this routine and recently we've seen others doing the same thing.
