Sun-Air

What Sun-Air does

SUN-AIR is the operating brand of Sundberg Aviation Group, a privately held Danish aviation company founded in 1978 and headquartered in Billund. The group operates four business units: SUN-AIR of Scandinavia (scheduled airline, suspended from 30 March 2025), JOINJET (worldwide ad-hoc business jet charter), SmuuthCare (24/7/365 air ambulance), and SUN-AIR Technic (aircraft maintenance, component overhaul, and spare parts). The group employs 120 people across subsidiaries in Thisted (Denmark) and Augsburg (Germany), and is owned by Niels Sundberg (CEO) and Kristoffer Sundberg.

The group's core assets are its fleet and maintenance infrastructure. The Dornier 328 Jet (32 seats, twin-engine, in service since 2005) anchors charter operations. JOINJET operates a diversified business jet fleet spanning Global 5500, Challenger 3500, Hawker 4000, Citation CJ2+, and Citation M2 with seating capacities of 5–14 passengers, distributed worldwide via partnerships with major air brokers. SmuuthCare runs Hawker 800 air ambulance aircraft equipped with medical systems for medical repatriation. SUN-AIR Technic runs a "one-stop maintenance concept" formed in 2016 by merging the former Samro and ScanTech workshops, covering major overhauls, landing gear, composites, wheels, brakes, spare parts sales, and a component exchange program for European and worldwide operators.

The business model is primarily transaction-fee-based across charter (ad-hoc quote pricing), professional services (MRO), and hardware sales (spare parts and component exchange). Distribution is direct enterprise sales (phone/email quote requests) and broker channels for JOINJET worldwide reach, with ground handling partnerships at Gothenburg Airport via Menzies Aviation and Swedavia. There is no publicly disclosed pricing, no subscription revenue, no platform or developer API, and no online booking outside corporate/travel-agency channels for scheduled services. The group generates revenue across B2B (MRO, charter brokers) and B2C (VIPs, corporate travelers, sports teams, medical patients) segments, with no disclosed financials, institutional investors, or cap-table data.

Core offering

SUN-AIR of Scandinavia is a private Danish aviation group that provides bespoke ad-hoc charter flights for VIPs, corporates and sports teams using the Dornier 328 JET, worldwide business jet charter via the JOINJET brand, 24/7/365 air ambulance operations through SmuuthCare, and one-stop aircraft maintenance (major overhauls, landing gear, composites, wheels, brakes) plus spare parts sales and a component exchange programme through SUN-AIR Technic. Operations span Denmark, Germany, Sweden, and worldwide via broker partnerships.

Product overview

SUN-AIR of Scandinavia operates a multi-brand aviation platform organized under the Sundberg Aviation Group, combining airline, charter, air ambulance and maintenance businesses. Its core offering, the SUN-AIR of Scandinavia scheduled network carrier (operating the Dornier 328 Jet from Billund), has been suspended from March 30, 2025 onwards. Three operational sub-brands complement the parent: JOINJET delivers VIP and corporate ad-hoc charter using a business jet fleet (Global 5500, Challenger 3500, Hawker 4000, Citation CJ2+, Citation M2); SmuuthCare provides 24/7 air ambulance services using Hawker 800 aircraft; and SUN-AIR Technic (formed in 2016 by consolidating the former Samro and ScanTech workshops) provides scheduled and business aircraft maintenance, component overhaul and spare parts from workshops in Billund and Thisted. The Ad Hoc Charter service sits alongside the brands, and the Online Check-in digital service supports passenger self-service. Passenger-facing support services such as baggage allowances, lost baggage handling, lost items, lounge access at Gothenburg Airport, travel assistance (wheelchairs, guide dogs, unaccompanied minors) and on-board catering extend the offering across the platform.
