The differing needs of the two shareholders, however, led to the break-up of the airline just six years later. The Singapore government preferred to develop the airline's international routes, while the Malaysian government had no choice but to develop the domestic network first before going regional and eventually international. MSA ceased operations in 1972, with its assets split between two new airlines; Malaysian Airline System (MAS), and Singapore Airlines. With the Singapore government determined to develop its airlines' international routes, it took the entire fleet of seven Boeing 707s and five Boeing 737s, which would allow it to continue servicing its regional and long-haul international routes. Since most of MSA's international routes were flown out of Singapore, the majority of international routes were in the hands of Singapore Airlines. In addition, MSA's headquarters, which was located in Singapore, became the headquarters of that airline.
