* Buenos Aires Aeroparque (AEP) - Rio Cuarto (RCU) - eff 03Apr17
This service, which is currently operated by Austral using E190's on a Cordoba (COR) - Rio Cuarto (RCU) - Buenos Aires Aeroparque (AEP) basis with 1x/daily round-trip will see the Cordoba (COR) legs dropped and will instead be operated 2x/daily from AEP to RCU round-trip, still by Austral E190's.

Operated by Austral E190's, presumably 1x/daily. This flight will depart EZE at mid-morning to allow connections from intercontinental flights to points along the east coast of Argentina all the way south to Ushuaia (USH).
