Depending on the weight of the bag, the costs of an overweight bag is going to range anywhere from as little as $50 to as much as $200 or more. For example, with United Airlines, overweight bags are going to cost $100 to $200 depending on how many pounds over the limit they are. The following is a chart showing the overweight luggage fee for popular airlines as of 2013:
Now compare that to the overweight bag fee you might get charged by an airline: Delta, for example, has overweight bag charges of $75 and American AAL, +6.74% $100 for bags that are 51 to 70 pounds â both higher than what UPS might charge you over a short distance.o if you shipped luggage and placed a value of $5,000 on it, youâd pay roughly $44 to ensure youâd be reimbursed $5,000 if the package was lost or damaged â still less than what some airlines charge (see Delta fees above).
