I haven't flown in probably a year and a half, maybe 2 now. But I understand the TSA is being snotty about carry on luggage and so you end up checking a lot of things. Maybe even expensive stuff like a camera or computer. Read about this way to make things a lot more secure, pack it with a weapon. Don't want to carry a real gun, well the TSA classifies a starter pistol as a weapon and if you pack one with your camera the TSA requires that the luggage be tracked and and not only lets
you lock it, but it is required
to be locked the whole way.
