I know that there is a hydrofoil over to Montevideo, but are there any other easy/cheap/quick ways to hop to other countries in South America from BA?
Are there any discount airlines that may fly to other cities?
If I fly into BA from the US, is there another city it's worth flying out (back to the US) of that is relatively easy to get to from BA?
I hope I'm making sense. We've never been to South America and are trying to make the most of it. We are used to going to Europe where we fly into one city and out another and in the middle hop around to multiple cities/countries...
