I will be traveling to Chile and Argentina with my cousin in October/November. We will be flying out of Miami and doing an Intrepid Tour that starts in Santiago, Chile, and ends in Ushuaia. We want to go to Buenos Aires from there before heading to Chicago.
Based on this, we would have 3 one-way flights: Miami-Santiago, Ushuaia-Buenos Aires, Buenos Aires-Chicago. From initial research, this would be over $2600.
I think it would be cheaper for us to get a return ticket from Miami to either Santiago or Buenos Aires. But this means we would either fly or get a bus from Santiago-Buenos Aires.
Does anyone have any experience with catching a bus from Santiago-Buenos Aires? What is the recommended company, estimated travel time, and approximate cost? Are there any entry/exit fees that we should be aware of? Any safety concerns?
When I look at flights, it seems return flights from Santiago-Buenos Aires are cheaper than one-ways. Are one-way flights uncommon?
Also, when I travelled to Peru I booked domestic flights with a travel agent and I noticed their prices were much cheaper than when I looked online. Is it similar in Chile and Argentina? Are there any travel agents or airlines you would recommend for booking flights?
Thanks in advance for your help!
