The TSA does not permit passengers to carry flares, gun powder, dynamite, fireworks, fuels, turpentine, chlorine, spray paint, liquid bleach, tear gas, fire extinguishers and other hazardous, flammable or explosive materials in checked or carry-on luggage.
Some items not permitted in carry-on luggage, such as box cutters, knives, hammers and snow globes, are permitted in checked luggage.
The TSA advises travelers to avoid packing jewelry, fragile items, cash, electronics and laptop computers in checked luggage. TSA agents may unpack and inspect your checked luggage. In addition, do not pack film or cameras with film, since screening X-rays may damage film.
