ROUTE UPDATES: American announces Buenos Aires Ezeiza (EZE) - Los Angeles (LAX) eff 19Dec18 + Cordoba (COR) - Miami (MIA) eff 02Apr19

Rumors had been circulating for about two weeks in the Argentine travel and aviation blog "Sir Chandler" that two big route announcements would be made soon and they were released today with both new routes to be operated by American Airlines.

* Buenos Aires Ezeiza (EZE) - Los Angeles (LAX) - eff 19Dec18 - 3x/weekly

To be operated with 787-9's.  It is expected that connections to Asia via American's Los Angeles (LAX) hub for business travelers is one of the main rationales behind the new service.  

This route was previously flown by Aerolineas Argentinas with A310's in the 1990's via Lima (LIM) or Mexico City (MEX).  

Some readers of other blogs have commented that the new service might take away passengers from American's existing daily service from Buenos Aires Ezeiza (EZE) to Dallas-Ft. Worth (DFW) and recall AA's flights between EZE and Chicago O'Hare (ORD) that operated for a couple of years in the late 2000's before being suspended.       
     
* Cordoba (COR) - Miami (MIA) - eff 02Apr19 - 4x/weekly

To be operated with 767-300's.  This route has been flown off-and-on several times by Aerolineas Argentinas over the last few decades using 707's, 727-200's and 737-200's on routings that included stops in Argentina and airports in other countries along the Pacific coast on the way up to Miami, also nonstop with 747's, and most recently using A340-300's between 04Jul15 and 29May16.

COPA and LATAM currently offer service from Cordoba (COR) to approx. 25-30 destinations in North America, Central America and the Caribbean through their respective hubs but American will connect Cordoba (COR) with approx. 100 destinations in the same regions though Miami (MIA) with the vast majority of them being in the US.

Worth 1x/daily for a total of 4x/daily flights and 28x/weekly.  Additionally, in the southern hemisphere summer high season from October or December (has varied by year) to March, the carrier operates a third daily flight between EZE and MIA.
