SAUDIA started out in 1945 with a single twin-engine DC-3 (Dakota) HZ-AAX given to King Abdul Aziz as a gift by the U.S. President Franklin D. Roosevelt. This was followed months later with the purchase of two more DC-3s, and these formed the nucleus of what in few years later was to become one of the world's largest airlines. Today SAUDIA has 149 aircraft, including the latest and most advanced wide-bodied jets presently available: B787-9, B777-268L, B777-300ER, Airbus A320-200, Airbus A321, and Airbus A330-300.
