A year later, LAN Airlines Sud Aviation Caravelle aircraft were acquired by AeroTal to operate the busiest routes of the company in Arauca and Leticia.

It was also decided by the AeroTal company board to suspend operations in Leticia to use the new jets on trunk air routes.

Three years later, a fourth Sud Aviation Caravelle was incorporated to AeroTal's fleet to accommodate for the enormous demand for the trunk air routes.

Then in 1979 the Civil Aeronautics Board (CAB) authorized cargo flights to Miami, for which a Boeing 707 was acquired through Leasing.

These gave the idea of starting to operate passenger flights to Miami, temporarily from Barranquilla, Bogotá, Medellín and San Andrés.

[4] The latter had been warned in a statement by Boeing, which mentioned problems with the ailerons and the rudder, leaks in the hydraulic and fuel system.

Also during that period there was a restructuring of AeroTal executives, and Avianca was requested to cover the airline's routes temporarily.

Finally, due to serious debts, AeroTal operations were permanently suspended because of everything that happened in those early eighties.

The way to cover the old debts and supply the public needs was sought, since at that time Avianca had suspended its cargo flights to United States.
