Aerolineas Argentinas recently discontinued its Cordoba (COR) - Miami (MIA) service for the fifth time since 1979. The previous four attempts had mixed success, with some attempts lasting much longer than others.
The blog Aeropuerto Internacional Cordoba outlined the history of airline service between these two cities, which is summarized below (see link below "Sources" at the bottom of this posting for full details in Spanish):
First Attempt - 1979 - 1983
Aerolineas flew the 707 from Cordoba (COR) to Miami (MIA) for four years until 1983, the longest that the carrier has ever maintained service on this route.
Departures were on Wednesdays and Sundays with the Wednesday flight stopping twice, in Jujuy (JUJ) in northern Argentina and Bogota (BOG), with the Sunday flight being nonstop.
This routine changed a little in 1980/81 with the Wednesday flight originating at Buenos Aires Ezeiza (EZE) and stopping in Cordoba (COR) and Bogota (BOG) before arriving in Miami (MIA). The flight was the same on Sundays but without the stop in Bogota (BOG). Jujuy (JUJ) still had its own flight to the US 1x/weekly via Bogota (BOG).
Second Attempt - 1985
The second try at service from Cordoba (COR) to Miami (MIA) was in 1985 as part of a marketing plan to establish Cordoba (COR) as a national hub for Aerolineas, given the city's central location in Argentina and being the city with the country's second largest population.
"Conexion Cordoba" involved flights to approx. 17-18 Argentine cities plus a couple of foreign destinations too.
The Miami (MIA) service had an inconvenient circuitous routing and even a change of aircraft, which probably explained its limited success.
The service operated 1x/weekly on Fridays using a 737-200 from Cordoba (COR) to Tucuman (TUC) and Jujuy (JUJ) where there was a change of plane to a 727-200, which proceeded northward to Guayaquil (GYE) and Bogota (BOG) before finally arriving in Miami (MIA). This service only lasted a few months being discontinued in 1985.
Third Attempt - 1994 - 1995
This was the most short-lived of all the Cordoba (COR) - Miami (MIA) services, lasting only 10 1x/weekly flights between 23Dec94 and 10Mar95 in the southern hemisphere summer.
The flights followed a Buenos Aires Ezeiza (EZE) - Cordoba (COR) - Miami (MIA) routing operated with 747-200's. Rarely did as many as 150 passengers board in Cordoba (COR) which apparently was considered not enough to justify operating the route again the following summer.
Fourth Attempt - 1998
This service flew 4x/weekly from Cordoba (COR) to Miami (MIA) nonstop with 747-200's from 01Jul98 to December when it was discontinued.
