What happens if my checked bag is overweight United?

United Airlines (UA) will charge the following for U S domestic flights for bags that are greater than the standard 50 pounds or 23 kilograms: 51 to 70 pounds or 24 to 32 kilograms: $100.00 USD to $200 USD extra per bag. 71 to 100 pounds or 33 to 46 kilograms: $400.00 USD extra per bag.



If your checked bag on United Airlines exceeds the standard 50-pound (23 kg) weight limit, you will be required to pay overweight baggage fees, which are added on top of any standard checked bag charges. As of 2026, United typically charges an additional $100 per bag for those weighing between 51 and 70 pounds, and a significantly higher fee of $200 per bag for those weighing between 71 and 100 pounds. Bags exceeding 100 pounds (45 kg) are generally not accepted at all. These fees are per way, meaning a heavy bag will cost you twice on a round-trip. To avoid these steep penalties, travelers are encouraged to weigh their bags at home or utilize a "LugLess" shipping service. If you have Premier elite status or are flying in United Business or First Class, your weight limit is often increased to 70 pounds for free, but for most economy passengers, the 50-pound threshold is strictly enforced at the check-in counter.
