Sun-Air of Scandinavia A/S, usually shortened Sun-Air, is a Danish charter airline headquartered in Billund, with its main base at Billund Airport. It used to operate scheduled services as a franchise of British Airways using their name and corporate design as British Airways - operated by SUN-AIR of Scandinavia A/S. The airline announced it would end its scheduled operations in March 2025 Starting that month, Sun-Air services would form a network linking with British Airways' own services at Copenhagen, Oslo and Stockholm. Under the British Airways franchisee arrangement, all scheduled services were operated under the British Airways Express brand. During 2001, in response to a complaint by Sun-Air, rival airlines Scandinavian Airlines and Maersk Air were fined around €52 million ($44 million) for engaging in anti-competitive behaviour following an investigation by the European Union.
During 2009, it was decided to restructure Sun-Air's charter division, leading to it being rebranded as JoinJet; Niels Sundberg's son, Kristoffer Sundberg, was appointed to head this subsidiary. It maintains a separate employee roster, which includes pilots, flight attendants, flight coordinators, and its own sales team. During the 2010s, Sun-Air became the biggest civil operator of the 328JET. On 25 February 2017, British Airways terminated its flights from Bremen to London and Manchester which were both operated by Sun-Air; the latter had maintained a base for these routes at Bremen Airport.
During 2017, Kristoffer Sundberg took over as CEO of Sun-Air while Niels Sundberg remained chairman of the board. The airline is wholly owned by Niels Sundberg and had 175 employees as of 2019. In January 2021, the company filed for insolvency for its German operational subsidiary Sun-Air of Germany and laid off most of its Germany based staff.
In March 2025, Sun-Air stopped its last remaining scheduled route between Billund Airport and London-City, ending 34 years of scheduled operations and their affiliation with British Airways. Citing a changed market, the airline uncovered plans to focus on any kind of not scheduled operations.
