Luggage Weight Fee Calculator

The standard economy class checked bag weight limit on most major US airlines is 50 lb (23 kg) per bag. International routes and premium cabin classes often allow 70 lb (32 kg). Bags exceeding the weight limit incur overweight fees. Bags over 70 lb (32 kg) may be refused as checked luggage on many carriers.

Overweight bag fees vary by airline and route. For domestic US flights on major carriers, a bag weighing 51 to 70 lb (23 to 32 kg) typically incurs an additional fee of $100 to $200 per bag. Some low-cost carriers charge more. This calculator uses your airline's fee schedule as user-editable inputs so you can enter the exact current charges.

Oversized bag rules are based on linear dimensions (length + width + height). Most US carriers limit checked bags to 62 linear inches (157 cm). Bags exceeding this limit typically incur an oversized fee of $150 to $200 per bag, separate from and in addition to any overweight fee. Bags exceeding 126 linear inches (320 cm) are generally refused as checked baggage.

Yes, if the total weight can be distributed between two bags each within the standard limit, this is often cheaper than paying the overweight fee. For example, if your one 70 lb bag incurs a $100 overweight fee and one $35 additional bag fee, the total is $135. Two 35 lb bags cost $35 each, totalling $70. However, verify your airline's specific policies before checking in.

No. International routes often have different (sometimes higher) overweight fees than domestic routes. Some international carriers include a larger weight allowance in the base fare, especially in economy class for transatlantic and transpacific routes. Always verify the specific route's allowance and fee schedule with your airline before packing.
