Whether you're an individual, small business, or large business, Southwest Airlines would LUV to help you with all of your shipping needs. First, we'll need a little information from you. Simply download the application, provide the applicable information to apply for either a Billable Cargo account or a Non-billable Shipper ID account, and fax the completed application to the Cargo Customer Care Center at 214-792-4199.
A Billable Cargo account allows Customers to charge the shipping costs to your Southwest Airlines Cargo account. Invoices are sent to the Billable Account each month for the previous month's charges.
A Non-billable Shipper ID account does not allow Customers to charge the shipping costs. Costs must be paid at the time of departure/arrival by either the shipper or the consignee.
The Transportation Security Administration (TSA) requires that Southwest Airlines may only accept cargo weighing 16 ounces or more from Known Shippers or TSA-approved Indirect Air Carriers. In order to ship cargo with Southwest Airlines, you must be a TSA approved Indirect Air Carrier or become a Known Shipper by completing the account application process.
