Eastern Airlines: the South American Route System, August 1982

A dreamy, pencil-sketch styled route Map from the pre-digital era adorned the back section of Eastern Airlines in-flight magazine in August 1982. This excerpt detailed the airline's famed Latin American Routes, which fanned out from New York and Miami, following a predominant Andean spine, with busy interconnections between bases in Panama City, Bogota, Quito, Guayaquil, and Lima, thinning out toward Santiago and Buenos Aires. Astonishingly, there were apparently no routes to Venezuela, or to the huge cities of Brazil. The route map shows connections through Miami to Washington, Houston and Los Angeles, and a single non-stop from New Orleans to Panama City. 

TACA: The Lima Hub, 2011

No corner of the globe has undergone such a radical re-alignment of aviation interests than Latin America, in which all but a handful of state carriers and private operators (not least including VIASA, VASP, Transbrasil, VARIG, Lloyd Aero Boliviano, Ladeco, Ecuatoriana, Aviateca, NICA, and Sahsa) have disappeared. In addition to the asphyxiatingly ubiquitous LAN Group, and a variety of promising mainline start-ups and a plethora of low-cost ventures, South America is now territory covered by Grupo TACA, through its 1999 merger with Avianca.

That marriage included the rebranding of a unit based at Lima, formerly known as TransAm but now operating as TACA Peru, with Avianca as a 49% shareholder. The division serves ten major cities from Santiago to Santa Cruz to Sao Paulo, and connects northwards to TACA's hubs in Central America as well as Mexico City and Miami.

Air Panama Timetable, April to October 1985

A one-page, one-color timetable from Air Panama Internacional, midyear 1985. Mutliweekly flights connected Panama City with Bogata, Caracas, Guayaquil, Lima, and Mexico City. Nonstop service ran daily between Tocumen International Airport and Miami. According to the Wikipedia entry, Air Panama reached as far as New York's JFK, as well as Guatemala City, with a variety of aircraft, including the DC-10 and B757, prior to its demise at the time of the American invasion of Panama in 1989.

Iberia: Western Hemisphere, February 2006

Iberia's Western Hemisphere routes in early 2006 showing, to a fault, its reliance on American Airlines to compliment its transatlantic system, particularly the radiating spokes out of Miami and Chicago. Its surprising that Iberia does not have more US destinations: nothing on the west coast, no service to Washington. Service to Boston's Logan airport has commenced since this time. Its Latin American links are proficient, but not over-abundant.

Over all, this cartography suffers from an extreme over-inclusiveness of code-share routes from American Airlines. This is further complicated by Iberia's historic base at Miami, which facilitated onward connections in Latin America. Its hard to discern among all these red lines just what IB metal serves which cities.
