On 7 January 2002, NAS took over the route from Stavanger to Newcastle, flying two round trips per day; this was the first route on which the airline did not wet lease the aircraft to Braathens, but operated the route in its own right. After Braathens was bought by Scandinavian Airlines System (SAS) in November 2001, all contracts that Norwegian had with Braathens for the routes on the Norwegian west coast were cancelled by SAS, as it wanted its subsidiary SAS Commuter to take the routes over. NAS had an 18-month cancellation period in its contract with Braathens; however, this was not respected by SAS - the contracts were terminated without notice. Following the purchase of Braathens by SAS, and the subsequent termination of its contracts, NAS announced in April 2002 that it would start domestic scheduled services as a low-cost carrier on the busiest routes. From 1 September 2002, the airline re-branded as Norwegian.
