I'm planning to travel around South & Central America early in 2014 and have been thinking about different options (which are all very open at this stage). Current thinking is visit Patagonia in January/February then fly up to Central America and make my way back down finishing in Brazil for the 2014 World Cup. However, my problem is I'm struggling to find airlines that fly between Santiago and Central America. Another option would be to fly from Buenos Aires. Any advice on flights/airlines would be greatly appreciated.
