Southern Airways Express

Southern Airways Express is a commuter airline operating across the United States with headquarters in Palm Beach, Florida. Southern Airways acts as a local service airline for dozens of cities across all U.S. time zones. Approximately one third of its routes are subsidized through the Essential Air Service program by the United States Department of Transportation.

In its Gulf, New England, and Hawaiian Regions, Southern operates from executive terminals, meaning that passengers are not required to check-in at the main passenger terminals, nor are they required to pass through Transportation Security Administration (TSA) security screening. In Southern's mid-Atlantic, Rocky Mountain, and California footprints, passengers embark and disembark through the primary secured (TSA) terminals. Southern has interlining agreements with Alaska Airlines, American Airlines, and United Airlines which provides passengers through-ticketing and baggage transfers.

Southern Airways Express is a subsidiary of Surf Air Mobility.
