Origins

Singapore Airlines began with the incorporation of Malayan Airways Limited (MAL) on 12 October 1947, by the Ocean Steamship Company of Liverpool, the Straits Steamship Company of Singapore and Imperial Airways. The airline's first flight was a chartered flight from the British Straits Settlement of Singapore to Kuala Lumpur on 2 April 1947 using an Airspeed Consul twin-engined airplane. Regular weekly scheduled flights quickly followed from Singapore to Kuala Lumpur, Ipoh and Penang from 1 May 1947 with the same aircraft type. The airline continued to expand during the rest of the 1940s and 1950s, as other British Commonwealth airlines (such as BOAC and Qantas Empire Airways) provided technical assistance, as well as assistance in joining IATA.Fact: date=October 2007 By 1955, Malayan Airways' fleet had grown to include a large number of Douglas DC-3s, and went public in 1957. Other aircraft operated in the first two decades included the Douglas DC-4 Skymaster, the Vickers Viscount, the Lockheed L-1049 Super Constellation, the Bristol Britannia, the de Havilland Comet 4 and the Fokker F27.
