Malaysia–Singapore Airlines was the multinational flag carrier of Malaysia and Singapore. The airline was previously renamed twice, being founded as Malayan Airways from 1946 to 1963, Malaysian Airways from 1963 to 1965, and ultimately in 1966 as a result of a joint ownership of the airline by the governments of the two countries not long after Singapore was expelled from Malaysia. It was headquartered at Robinson Road in Singapore.
