With airline deregulation in 1978, Allegheny Airlines began expanding with new DC-9s and used 727s. This one was obtained from United Airlines in August 1978. As they expanded outside their local area, the airline changed their name to US Air in 1979. N753AL was sold to Alaska Airlines July 26, 1982 and re-registered N753AS. Operated by the airline for ARCO oil support until used for a short time for their own freight operation. Sold in 1994, the airplane was finally scrapped after 2003 with the forward fuselage stored at El Mirage, CA with Aviation Warehouse and available for film work.
