1. Different objects

The air waybill is a cargo transportation contract between the centralized shipper and the shipper. The two parties to the contract are cargo A, B and the centralized shipper respectively.

The air waybill serves as a cargo transportation contract between the air transport company and the centralized shipper, and the parties are the centralized shipper and the air transport company. There is no direct contractual relationship between the cargo owner and the air transport company.

2. Different functions

The function of the master waybill is to inform the airline of relevant cargo data, including the number of pieces, weight, and volume of the cargo. And the relevant consignor and consignor information and the destination to be shipped to.

The function of the sub-waybill is to let the cargo owner know the airline on which the relevant goods are arranged and the flight company booked, and to inform the freight forwarder of the relevant weight and volume data of the goods received, so as to collect the relevant freight from the cargo owner.

Extended information

According to the provisions of paragraphs 1 and 4 of Article 7 of the Warsaw Convention, the shipper shall fill in the original air waybill in triplicate, and the carrier shall If the air waybill is filled in at the request of a person, it shall be deemed to be filled in on behalf of the shipper in the absence of proof to the contrary. The legislative orientation of other legal systems on this item is also consistent with the Warsaw Convention.

It can be seen that the person responsible for filling out the air waybill is the shipper, and the shipper should be responsible for the cargo information provided by itself. And to take a step back, even if the shipper fails to fill it out for various reasons, the air carrier has the right to fill it out on the shipper's behalf without other evidence.

The "filling in on behalf of" here is actually an agency relationship. As the principal, the shipper is still responsible for the filled-in content according to legal provisions. Therefore, the author reminds that the legal provisions here are beneficial to the carrier, so the correct way for the shipper to protect their legitimate rights and interests is to fill in the freight bill accurately and reasonably.
