The story
Aerovias Guest was founded in June 1946. In the 1950s, the airline began an international partnership with Scandinavian Airlines (SAS) after SAS purchased a share of the airline. The airline's name was later changed to Guest Aerovias Mexico. SAS sold its share of the airline in 1961.
In early 1963, the airline flying as Guest Aerovias Mexico was operating daily nonstop Douglas DC-8 jet service between Mexico City and New York City as well as nonstop DC-8 flights four days a week between Mexico City and Miami and was also flying de Havilland Comet 4C jet service twice a week on Mexico City - Guatemala - Panama City - Caracas and Mexico City - Guatemala - Panama City - Bogota routings. Aerovias Guest was then taken over by Aeronaves de Mexico later in 1963 and the company name was retired.
