As part of the Department of Homeland Security, the Transportation Security Administration (TSA) is responsible for ensuring that the nation's transportation systems remain safe and protected. In addition to screening passengers, the TSA makes rules regarding what passengers can take with them onto an airplane in their carry-on luggage. The rules listed were in effect in February 2010, but are subject to frequent change with or without notification by the TSA.
No sharp objects may be carried on-board in a person's carry-on luggage, with the exception of scissors that have blades of less than 4 inches. All other sharp or bladed objects can be transported in a person's checked baggage.
Any sporting goods that may be used as a potential weapon may not be carried in a person's carry-on luggage. This includes items like baseball bats, archery equipment, golf clubs, hockey sticks, pool cues and anything else that is potentially dangerous. These items may be included with the person's checked luggage.
No guns, firearms or explosive devices or gunpowder of any kind may be carried in a person's carry-on baggage. This includes BB guns, flare guns, pellet guns, replica guns, as well as gun parts and ammunition. Also, no lighter fluid, fuels, gasoline or other flammable material may be brought on-board.
No person may take in their carry-on baggage any axes, power tools, hammers, saws, crowbars or any other tool bigger than 7 inches in length. Screwdrivers, wrenches and pliers may be carried in a person's carry-on luggage as long as these items do not exceed 7 inches in length.
Personal liquids, gels or aerosols must be contained in 3.4 oz. containers or smaller. They must be placed in a single, quart-sized, zip-topped, clear plastic bag. This bag must be removed from their carry-on luggage and placed in a bin for X-ray screening prior to passing through the security checkpoint.
