Southwest Cargo® likes to keep things simple, and that's why we offer you effortless shipping with fast, efficient service. Shipping Cargo can seem complex with a lot of rules, so here's our 101 lesson on shipping on Southwest Airlines® .
Whether you're an individual or a large business, the Transportation Security Administration (TSA) mandates Southwest Airlines may only accept Cargo weighing 16 ounces or greater from Known Shippers or TSA-approved Indirect Air Carriers (IAC).
A Known Shipper is an individual or business that has an established reputation in the shipping community and is offering their own goods for transportation. To become a Known Shipper, you must complete a Cargo account application. Additional supporting documentation may be requested to complete the application approval process. Once your account is established, please remember to bring the account number to ship with Southwest Cargo.
If you are a Courier or Freight Forwarding company you may be known as an Indirect Air Carrier, (IAC). If you are already a TSA approved IAC, then you will need to provide a copy of your Indirect Air Carrier certification letter along with your account application.
For details on how to become a TSA approved company, please contact:

Southwest Airlines does not accept shipments weighing 16 ounces or greater from an Unknown Shipper. However, we will accept a small package, provided it is one piece weighing less than 16 ounces and a valid government-issued photo identification is provided.
