President of SAS Resigns: Jan Carlzon stepped down after a dozen years as chief executive of Scandinavian Airlines System to work on forging an alliance of SAS, KLM, Swissair and Austrian Airlines. Carlzon will continue to represent SAS in negotiations toward establishing a four-airline joint holding company, called Alcazar, SAS said. The carrier immediately named Jan Reinas, president of SAS Norway, group president and chief executive until April, when he plans to leave SAS. Carlzon, 52, joined SAS in 1980 as chief executive and became president less than a year later.
