Aerovias Sud Americana

Aerovias Sud Americana dba ASA International Airlines (ASA) was one of the first cargo airlines to fly between the United States and Latin America, a US carrier certificated to fly air freight on a scheduled basis between Florida and Latin America in 1952 by the Civil Aeronautics Board (CAB), the now-defunct Federal agency that, at the time, tightly regulated almost all US commercial air transportation. ASA was undersized relative to contemporary freight airlines, but operated successfully in the 1950s nonetheless. Thereafter political instability, changing regulations and regulatory inertia impacted ASA and it failed to make the transition to jets. The CAB denied attempts by Riddle Airlines (later known as Airlift International) to merge with ASA before and after ASA collapsed in 1965.
