Crossair  Crossair Ltd. Co. for Regional European Air Transport () was a regional airline headquartered on the grounds of EuroAirport Basel-Mulhouse-Freiburg in Saint-Louis, Haut-Rhin, France, near Basel, Switzerland. It became Swiss International Air Lines after taking over most of the assets of Swissair following that airline's bankruptcy in 2002. Founded as a private company under the name "Business Flyers Basel AG" by Moritz Suter, it changed to "Crossair" on 18 November 1978, before the beginning of scheduled services on 2 July 1979 with flights from Zürich to Nuremberg, Innsbruck and Klagenfurt. It was headquartered at Zurich International Airport in Kloten in 1985. It added charter services for major shareholder Swissair in November 1995. On 31 March 2002, Swissair passed out of existence as most of its assets were taken over by Crossair which then changed names to Swiss International Air Lines. Crossair operated the following aircraft. Crossair flew from Basel, Bern, Geneva, Lugano and Zurich. Crossair was very interested in serving from several hubs and, therefore set up a multi-hub business plan. Crossair set up a Eurocross scheme from their Basel base which was set up to help them serve smaller airports and transfer their passengers to larger hubs with short transit times (only around 20 minutes) This helped Crossair link with their partners, such as Swissair from Zurich. Crossair also operated flights between Swiss airports. Crossair was headquartered on the grounds of EuroAirport Basel-Mulhouse-Freiburg in Saint-Louis, Haut-Rhin, France, near Basel, Switzerland. In 2002 the name "Crossair" was replaced with "Swiss International Air Lines" on the head office building.
