I could take the bus from BsAs to Rosario, then fly ROS-COR, and COR-AEP.
I would fly ROS-COR only if the fare was ridiculously cheap or if, for some reason, you only consider flying. Both cities are 400km apart and connected through a very good motorway. A coach will take 6 hours or less versus some 4 hours if flying, considering getting to the airport, check-in, flight time, disembarking, etc. So while the coach takes a little longer, it's usually much cheaper. The coach stations at Rosario and Córdoba are quite central, whilst airports are far away and taxis tend to be expensive, especially in Córdoba, where they have a special (more expensive) fare for airport-downtown trips.
