As of 2015, Delta Airlines has a variety of baggage restrictions depending on the origin and destination of one's flight and the cabin status of the passenger. Generally, Delta allows passengers one free carry-on bag and one free personal item, while checked bags run a variety of rates.
Delta has the following restrictions as of July 2015. Carry-on bags cannot measure longer than 45 inches in combined length, width and height, as they must fit in overhead compartments. No maximum weight applies to carry-on bags. Liquids, gels or pastes must remain under 3.4 ounces per container. No weapons, ammunition, or explosive or flammable substances are allowed in carry-on baggage. Personal items include purses, briefcases, laptops and small bags.
Checked baggage on Delta Airlines flights can weigh a maximum of 50 pounds if in the main cabin, or 70 pounds if a Delta One, first- or business-class passenger. All checked bags must be no longer than 62 inches when combining length, width and height. Overweight and oversized baggage incur additional fees.
For domestic U.S. flights, main cabin passengers may check their first bag for $25. On international routes, main cabin passengers are often allowed one checked bag for free. Delta One, first and business-class passengers are allowed three free checked bags on domestic routes and two on international routes. All passengers must pay higher fees for additional checked bags.
