Southern Airways Express

What Southern Airways Express does

Southern Airways Express is a US regional commuter airline founded in 2013 and headquartered in Pompano Beach, Florida. It operates as a subsidiary of Surf Air Mobility (NYSE: SRFM) alongside Mokulele Airlines in Hawaii. The carrier runs scheduled passenger service with Cessna Grand Caravans (configurations of 28 or fewer seats) to approximately 14 destinations across the East, Central, and West regions of the United States, carrying roughly 300,000 passengers and operating more than 60,000 departures annually. It holds interline agreements with Alaska Airlines, American Airlines, and United Airlines, enabling connections to each major US legacy carrier's network.

The company's central technical differentiator is SurfOS, an AI-enabled operating system co-developed with Palantir. SurfOS underpins BrokerOS, a charter sales module launched in December 2025, and will host OperatorOS, a crew and fleet management module scheduled for the second half of 2026. Disclosed operational outcomes attributed to SurfOS include a 6% reduction in airline unit costs, a 15% reduction in charter costs, a 32% staffing reduction, and a 98% flight completion rate. The carrier also achieved Safety Management System compliance in April 2026, one year ahead of the FAA mandate. Fleet commitments include 100 firm plus 50 option Cessna Grand Caravan EX aircraft from Textron Aviation and 25 electric aircraft from BETA Technologies.

Southern Airways Express generates revenue through three channels: scheduled passenger flights with fares starting at $39; Surf On Demand charter service, which grew 77% year-over-year in Q1 2026; and the Elevate loyalty program, launched in December 2025 alongside the iOS application released in June 2026. The parent company, Surf Air Mobility, reported Q1 2026 revenue of $25.6M and full-year 2026 guidance of $128-138M, with FY2026 EBITDA guidance raised 40% year-to-date. Capital structure was reinforced by a $30M raise in April 2026, split between a $15M aircraft-backed credit facility and $15M common equity.
