We are looking to book the following (same day) flights:
We will have been in Buenos Aires already and due to time constraints can't spend another night there on the way back.
We do not know:
1) If these airports are near enough to each other so we can make the flight to Rio. Traffic etc. may make it impossible but we don't know.
2) How we can get between the two airports and how much it costs.
Any information on this would be greatly appreciated.
