Cargo on a Southwest flight can be tracked by using the online shipment tracking form that is available on the official Southwest Cargo website. The cargo can be tracked by using its air waybill number, cargo account number or the cargo companion GPS device attached to it.
The search form that is available on the Southwest Cargo website allows for up to 10 unique air waybill numbers to be inputted. Alternatively, cargo can also be tracked by checking the status of the flight that it is being shipped on. This method can track flights by using their departure and arrival cities, departure flight number or arrival flight number.
