Before trying to travel with any type of ammunition, call your airline or travel agent to determine if it is permissible. If you pack firearms or ammunition, they must be declared at check-in, and there are specific packaging instructions for them. Personal arms or ammunition which are small need to be packed safely in wood, metal or other specially-designed packaging. It is mandatory for firearms to be unloaded and packed in a hard-sided container. Gunpowder and flares are not allowed on airplanes.
TSA has a system called 3-1-1 regarding the amount of liquids, gels and aerosols which passengers can safely take onboard an aircraft. Gels or liquids in 3-ounce containers or smaller may be placed in a 1-quart size clear plastic zip-top bag, one bag per traveler. Larger liquids must be declared. Necessary items like medication and infant formula will be allowed in reasonable quantities in addition to the 3-1-1 amount.
Spare lithium batteries must not be packed in checked baggage; they are only allowed in carry-on baggage. The number of spare batteries permissible on an airplane are not restricted if they are for personal use. Button cells for hearing aids, AA, AAA and laptop batteries are allowed in the carry-on. All devices containing batteries must be protected from accidental activation by putting the switch in the "off" position.
Tools like hammers, saws, drills and drill bits, and hatchets are allowed in checked baggage, but not in carry-on. Screwdrivers, wrenches and pliers less than seven inches in length are allowed in carry-on bags. However, all sharp objects must be put in protective covering to prevent injury to baggage handlers and security officials.
