Why is there no progress in the civil aviation express number?

The delay in updating the progress of the civil aviation express number may be caused by the following factors: 1. The waybill information was not entered in time. After the courier company collects the goods, it needs to enter the waybill information, including the shipper, consignee, address and other information. If the information is not entered in time, it may be that the single number cannot be queried or the progress has not been updated. 2. Logistics information transmission delay. Once the waybill information is entered into the system, the courier company will start to arrange the delivery time. However, due to the influence of weather, traffic and other factors, the transmission of logistics information may be delayed, resulting in the inability to update the query progress in time. 3. The logistics node information is not updated in time. The whole logistics and transportation process involves many links, and the courier company will update the information according to different nodes. However, due to various reasons, the information of some nodes may not be updated in time, which leads to the delay in updating the query progress. To sum up, the reasons for the failure to update the progress of the civil aviation express order number in time may be the delay in entry, the delay in information transmission or the failure to update the node information in time.
