Who We Serve
- Known Shippers
- Indirect Air Carriers
- Unknown Shippers
Whether you're an individual or a large business, the Transportation Security Administration (TSA) mandates Southwest Airlines may accept cargo weighing 16 ounces or greater from Known Shippers or TSA-approved Indirect Air Carriers (IAC) only.
Known Shippers
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 and fax it in to 214-792-4199. Additional supporting documentation may be requested to complete the application approval process. Once your account is established, please remember to bring the account ID number to ship with Southwest Airlines Cargo. For more information, please visit the How to Ship page.
Indirect Air Carriers (IAC)
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.
