Where can I find the best deals for air travel to South America?

From Chicago to Sao Paulo.

Make sure you book well in advance.

cheaptickets.com
travelocity.com
expedia.com

Look them up in these three engines and see what's the best rate for you. Contact your credit cards and find out which one give you free insurance when you travel so you don't have to pay insurance extra. I believe that Discover gived their clients insurance for flights.

Ps- Usually it is cheaper to get the ones that have stops istead of non-stop flights.


Good luck and have fun.
