Typically, each passenger is allowed one checked bag for an average $25 fee on most airlines. If you plan to bring more than one, you will accrue additional charges for each extra bag. The maximum size for these bags is typically 62 linear inches (the sum of length, width, and height). The bag can be 28” by 20” by 14,” 29” by 20” by 13,” or some other combination as long as the total sum adds up to 62.” If you check a bag exceeding these dimensions, you will be charged an “over-sized” fee which can be expensive. Therefore, it is best to buy an appropriately sized bag before your trip.Today, many airlines charge large fees for overweight luggage. Most airlines mandate a 50 pound weight limit for checked baggage. Many will allow you to check a 51- 71 pound bag for a fee ranging from $50-$200 per bag. For bags above 71 pounds it is recommended to check with your airline on their fees and policies. These weight limits are subject to differences depending on the airline, so it is important to check before leaving, and weigh your luggage with a luggage scale at home.
