What are the guidelines for shipping freight with Southwest Airlines?

Shipping freight with Southwest Airlines is managed specifically through Southwest Cargo, which has established guidelines outlining size and weight restrictions for shipments. This ensures that all freight transported by the airline adheres to safety regulations and operational capabilities. Southwest Cargo's framework allows for efficient processing and handling of freight while providing shippers with clear expectations regarding what can be transported.

The guidelines help to avoid potential issues that could arise from overloading or improperly sized shipments, making freight shipping more reliable for customers. Additionally, these restrictions help maintain the integrity of regular passenger flights, as they ensure that freight does not impede on the performance or safety of the aircraft.

In contrast, shipping freight free of charge is not a viable practice in the commercial airline industry, as this would not be sustainable for operations. Moreover, while domestic and international shipping may be available, the existence of size and weight guidelines is crucial and binds the services provided by Southwest Cargo. Lastly, indicating that no guidelines exist would lead to confusion and operational inefficiencies, which contradicts the structured approach taken by reputable cargo services like Southwest Airlines.
