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:
Normal baggage fees are nothing compared to overweight charges. If you take a 71 pound suitcase on Delta, resign yourself to paying $200 (each way) on top of the regular checked-bag fee. On certain international flights, United charges overweight fees as high as $400.he $100 carry-on fee. That's not a misprint, Spirit Airlines charges one hundred bucks each way for a carry-on bag if you wait to pay for it at the airport gate. Frontier used to charge the same but lowered it to $50, possibly to match Allegiant.
