AMERICAN AIRLINES REORGANIZES EXECUTIVES

   American Airlines made several changes in executive assignments, including promoting Robert W. Baker, executive vice president-operations, to vice chairman.
   Baker will work directly on all aspects of the airline with Donald J. Carty, chairman and chief executive officer.
   Gerald J. Arpey, senior vice president-finance and planning and chief financial officer, will succeed Baker as executive vice president-operations. Arpey’s duties include maintenance and engineering, flight, operations planning, purchasing, corporate real estate, AA Cargo and America Eagle.
   In addition, Daniel P. Garton was appointed executive vice president-customer service and Michael W. Guff was named executive vice president-marketing and planning.
   Arpey and Garton are viewed as potential successors to Carty, who has led American and AMR Corp. since 1998.
