Southern Airways Express, a commuter airline based in Palm Beach, Florida, is the largest of its kind in the United States. Established in 2013, it serves nearly 40 domestic destinations across five time zones. The airline's operations are supported by the United States Department of Transportation (DoT) through the Essential Air Service program, which subsidizes many of its routes to smaller communities.
The airline operates over 30 aircraft including models such as the Cessna Caravan and Grand Caravan, King Air Super 200, and Cessna Bravo. Southern Airways Express adheres to a customer-focused philosophy encapsulated in their mantra: “Every Passenger, Every Day, on Every Flight.” Each year, they transport hundreds of thousands of passengers on more than 200 daily departures under both its own brand and Mokulele Airlines.
In recent years, Southern Airways has expanded significantly after acquiring Mokulele Airlines in 2019. Both airlines are now subsidiaries of Surf Air Mobility following Southern's acquisition by Surf Air in 2023. The company maintains interline partnerships with major carriers like American Airlines, Alaska Airlines, and United Airlines.
