Each airline sets its own policies for the number of bags you may check and the maximum size of those bags. The most common size restrictions are 50 pounds in weight and 62 linear inches. To measure the linear inches, measure the length, height and depth of the bag, and then add those measurements together. Some airlines, such as Delta and United, permit elite passengers to check bags weighing up to 70 pounds. Elite travelers include passengers in first class or business class as well as certain credit card holders. Some airlines limit the total number of bags each passenger may check. For example, Delta’s limit is 10.
Most U.S. airlines charge per-bag fees beginning with the first checked bag. Exceptions include JetBlue, which allows all passengers to check one bag for free, and Southwest, which allows two free checked bags per passenger. Some airlines provide a free baggage allowance for elite passengers as defined above. Each airline sets a sliding scale for bag fees in which the first few bags cost less per bag. For example, as of August 2013, Delta charges economy passengers on domestic itineraries $25 for the first checked bag, $35 for the second, $125 for the third, and $200 per bag for additional checked bags. Most airlines accept overweight bags to 100 pounds or oversized bags up to 80 linear inches for an additional fee. Bag check fees are cumulative, so if your bag weighs 100 pounds and is 80 linear inches, you must pay the bag check fee, the overweight fee and the oversized fee.
The Transportation Security Administration prohibits all passengers from transporting certain hazardous materials on board commercial aircraft. Gunpowder, flares, fireworks and other explosive devices are not permitted. Flammable items such as lighter fluid, gasoline and cooking fuels are prohibited. Disabling chemicals are also forbidden, including pool chlorine, liquid paint and tear gas. Some airlines have additional restrictions, and the TSA guidelines are subject to change at any time. Check with your airline shortly before your flight.
Many airlines extend free baggage allowances to members of the U.S. military. Some airlines, such as United, extend some benefits to military members and their dependents traveling on personal time. Others restrict these benefits to uniformed military with official orders. Free baggage allowances vary widely between airlines and are subject to change. Contact your airline before your trip for the latest information.
