Austrian Airlines AG is the flag carrier airline of Austria, headquartered in Vienna. Together with regional subsidiary Austrian Arrows and charter arm Lauda Air, it operates scheduled services to over 130 destinations. Its main base is Vienna International Airport, with a hub at Innsbruck Airport. In 2007 the Austrian Airlines Group had 10.8 million passengers.

The airline was founded on 30 September 1957, making its maiden flight on 18 March 1958 when a Vickers Viscount 779 took off from Vienna for London, England via Zurich. Austrian Airlines was formed through the merger of Air Austria and Austrian Airways. It launched domestic services on 1 May 1963. The airline's transatlantic services began on 1 April 1969 with a Vienna to Brussels and New York service in co-operation with Sabena.

Austrian became a member of the Star Alliance in 2000. That year, Austrian acquired Lauda Air, an airline whose operations included long haul flights, and acquired Rheintalflug on 15 February 2001. Its name was shortened to Austrian in September 2003 when it rebranded its three constituent carriers. On 1 October 2004 the Flight Operations Departments of Austrian and Lauda Air were merged into a single unit, leaving Lauda Air as a brand name only for charter flights.
