Generally speaking, L/C will not be used for air transportation, because if it is air transportation, you can pick up the goods without a bill of lading. Since it is air freight, the goods must be urgent, and it takes time to issue and issue the bill of lading. In that case, why do people fly?

I met the problem you mentioned above. This is very simple. You only need to have the signature of any one of them, such as the captain, the shipping agent or the carrier. Generally speaking, the bill of lading will be signed by the captain, freight forwarder or carrier. If you are not sure, you can send the requirements of the bill of lading to your freight forwarder or shipping company, and they must know how to operate it.
