Updating the March 25, 2012 post:
Austral is starting today (June 1) a semicircular routing starting in COR all the way to CRD and back in the opposite direction:
Cordoba (COR) - Mendoza (MDZ) - Neuquen (NQN) - Comodoro Rivadavia (CRD) on 1,3,5 (Monday, Wednesday, Friday)
Previously it was announced that the route would start at Buenos Aires - Ezeiza (EZE) and circle all the way back to there.
The routing now has a name "Corredor Petrolero" with all of the cities on the route, except Cordoba, being a part of Argentina's oil industry.
The new service is very similar to a route presently being flown by SOL Lineas Aereas, a small private carrier, with Saab 340's. Presumably the airline has been successful on the route possibly giving Aerolineas Argentinas / Austral the idea of operating it themselves.
