Checked Bag Fees and Airline Policies
Most major U.S. airlines charge a fee for the first checked bag on domestic flights, typically ranging from $30 to $35 per bag, according to current carrier fee schedules. Delta Air Lines, United Airlines, and American Airlines all list checked bag fees near this range for standard economy tickets sold directly by the airline. Southwest Airlines remains an exception, allowing two checked bags at no extra cost under its current policy. International flights often have higher checked bag fees, and many carriers set the first bag fee at $40 to $100 depending on the route and fare class. Low-cost carriers such as Spirit and Frontier usually charge more for checked luggage if it is not pre-purchased online, with fees rising at the airport counter. Travelers can find the latest fee tables on airline websites and third-party travel policy pages like the one published by Forbes covering airline baggage fees and policies.

Baggage fee revenue has become a significant part of airline ancillary income, with the U.S. Department of Transportation publishing annual reports on carrier fee collections. In recent years, U.S. airlines collectively collected billions of dollars in baggage fees, making checked luggage a major revenue stream beyond ticket sales. Fee structures vary by elite status, with top-tier frequent flyers often receiving free checked bags on domestic itineraries. Basic economy fares almost always include a checked bag fee, even for the first bag, while main cabin and higher fares may include one free bag.

Checked Bag Size and Weight Limits
Standard checked bag size limits in the U.S. are set at linear dimensions of 62 inches (158 cm) for most domestic carriers, measured as length plus width plus height. Weight limits commonly range from 50 to 70 pounds (23 to 32 kg) per bag, with some international carriers enforcing lower thresholds on transatlantic routes. Airlines may apply oversized or overweight fees if a bag exceeds these limits, with charges often starting around $100 to $200 per bag. Cargo specifications for checked luggage are designed to fit standard aircraft bins and loading systems, which is why linear dimensions are the primary measurement. The International Air Transport Association (IATA) publishes recommended baggage dimensions that many global carriers follow for interline and codeshare flights. IATA baggage guidelines
Weight enforcement varies by carrier and route, with some airlines using check-in scales and others relying on random audits at the gate. Airlines such as Delta and United list weight limits of 50 pounds for most domestic checked bags, while some international flights allow up to 70 pounds. Oversized bags that exceed linear dimensions may be charged as special items, and some carriers require advance notification for items over 115 inches in total linear dimensions. Passengers who frequently check heavy bags should review their airline's fee schedule and consider programs or credit cards that offer baggage fee reimbursements. Delta checked baggage policy
Checked Baggage Safety, Tracking, and Mishandling Rates
The DOT tracks mishandled baggage rates across U.S. airlines, reporting the number of bags lost, delayed, or damaged per 1,000 passengers checked. In recent years, the mishandling rate for U.S. carriers has remained in the range of 5 to 7 bags per 1,000 passengers, with peak periods such as holiday travel seeing higher incident numbers.
