Most sharp objects, sporting goods, guns and other firearms, explosives and flammable items are strictly prohibited in carry-on baggage. However, if properly wrapped or covered, many of these items are allowed in checked baggage, which goes through a rigorous screening process in airport security lines.
The TSA allows all passengers one carry-on bag and one personal item such as a purse, briefcase or laptop case. Passengers may also check a large suitcase or bag. Some airlines offer to check the first bag free, while others charge a fee. Check with your preferred airline for its policy on checked baggage.
TSA has determined that liquids and gels are safe to bring aboard the airplane, in limited quantities. For carry-on luggage, liquids must not exceed 3.4 oz., or 100 milliliters. They must be sealed within a 1-quart clear plastic zip-top bag; each passenger is limited to one 1-quart bag.
