Brussels Airlines (stylized as brussels airlines) is the flag carrier and largest airline of Belgium based and headquartered at Brussels Airport. It operates to over 90 destinations in Europe, North America and Africa and also offers additional charter services, maintenance and crew training. The airline is a member of the Star Alliance as well as the International Air Transport Association and the Association of European Airlines. The airline's IATA code SN is inherited from its predecessors, Sabena and SN Brussels Airlines. Lufthansa purchased 45% of the company in 2009, and on September 29th 2016, Lufthansa announced it would purchase the remainder of Brussels Airlines for €2.6 million euros. The transaction was completed in early January 2017.

Brussels Airlines was created following the merger of SN Brussels Airlines (SNBA) and Virgin Express. On 12 April 2005, SN Airholding, the company behind SNBA, signed an agreement with Richard Branson, giving it control over Virgin Express. On 31 March 2006 SNBA and Virgin Express announced their merger into a single company. On 7 November 2006, the new name, Brussels Airlines, was announced at a press conference at Brussels Airport. Brussels Airlines began operations on 25 March 2007.

On 15 September 2008, it was announced that Lufthansa would acquire a 45% stake in Brussels Airlines with an option to acquire the remaining 55% from 2011. As a part of this deal, Brussels Airlines would join Star Alliance. From 26 October 2008, the ICAO code was changed from DAT to BEL.
