Crossair later changed its name to Swiss International Air Lines, and the new national airline officially started operations on 31 March 2002. At the time, both Swissair and Crossair were part of the same holding company, SAirGroup. Swissair's biggest creditors, Credit Suisse and UBS, sold part of Swissair's assets to Crossair, which had been Swissair's regional counterpart. The new airline lost US$1.6 billion from 2002 to 2005. Forty percent of Crossair's income came from Swissair. Swiss was formed after the 2002 bankruptcy of Swissair, Switzerland's former flag carrier.
