What discount might airlines offer to offset the added weight of a shipper-provided air container?

Airlines may offer a percentage discount to the freight rate when a shipper provides an air container that increases the weight of the shipment. This approach helps that airline manage costs associated with the extra weight, as heavier shipments can incur higher operational costs due to fuel usage and handling. By providing a percentage discount, the airline can incentivize shippers to use their own containers while still retaining profitability. This kind of arrangement accommodates both the airline's need to maintain competitive pricing and the shipper's interest in controlling shipping costs, forming a mutually beneficial relationship.

In contrast, a flat fee discount may not accurately reflect the variations in weight or value of different shipments, making it less appealing for both parties. Offering no discount at all could deter shippers from utilizing their air containers, as the increased weight would likely translate into higher costs without any offsetting benefit. A discount based on delivery time does not correlate with the extra weight introduced by a shipper-provided container and, therefore, is unrelated to this situation.
