Edelweiss Air is a Swiss leisure airline wholly owned by Swiss International Air Lines and the Lufthansa Group. It operates flights to European and intercontinental destinations from its base at Zürich Airport.

The airline was founded on 19 October 1995 in Bassersdorf, Switzerland, with just one aircraft, a McDonnell Douglas MD-83. The company's name is derived from the Swiss unofficial national flower, the Edelweiss, which is also painted on its airplanes.

The fleet was subsequently expanded and renewed. In 1998, new Airbus A320-200s were introduced to replace the MD-83s, and in 1999 long-haul flights were commenced using the Airbus A330-200.

For seven consecutive years between 2001 and 2008, Edelweiss Air received the golden Travelstar Award for its excellent achievements.

Until November 2008, Edelweiss Air was wholly owned by Kuoni Travel Ltd and had 190 employees, when the operating rights were sold to Swiss International Air Lines, in exchange for sale rights of hotel capacities via the Swiss sales network. Following Swiss International Airlines being been acquired by the German Lufthansa Group in 2005, Edelweiss Air also became a subsidiary of Europe's largest airline group at the same time it was acquired by Swiss.

As of March 2011, Edelweiss Air added the larger Airbus A330-300 to its fleet, with an order having been placed on 5 April 2010. In July 2015, it has been announced that Edelweiss will receive four Airbus A340-300s between 2017 and 2018 previously operated by its parent Swiss International Air Lines. The aircraft will be used to expand the route network.
