All airlines have certain luggage restrictions regarding the size, weight and number of bags you are allowed to carry on to a flight. Domestic flights usually allow each passenger one carry-on bag and one personal item that fits under the seat, according to AirSafe.com. The rules for carry-on luggage on international flights vary by airline. Contact your airline for specific carry-on luggage restrictions.
The weight and number of checked bags allowed varies per airline. Some airlines allow passengers to check bags for free, while other airlines charge for each bag checked. Bags over an airline-specific weight may incur extra fees. Contact your airline to find out the specific size and weight allowances for checked baggage.
The amount of liquids, gels and aerosols permitted in carry-on luggage is strictly regulated by the Transportation Security Administration. Passengers may carry on liquid and gel products in containers no larger than 3.4 fluid ounces and no more containers than will fit in a quart-size zip-top bag. After passing through security, passengers may purchase and carry on liquid and gel containers of any size.
Items that are forbidden in carry-on luggage but allowed in checked luggage include sporting goods such as bats, golf clubs and pool cues; cutting instruments such as carpet knives and metal scissors with pointed tips; firearms including pistols and BB guns and ammunition.
Items that are not allowed in carry-on luggage or checked luggage include explosive and flammable materials such as blasting caps, hand grenades or gasoline; disabling chemicals such as liquid bleach, spray paint and tear gas; and flares.
