I am planning a trip to South America to go ahead in March 2013, to return in September 2013 which is about 6 months. I think that if I book the right flights here and back wisely I could save a lot of money.. I'm not worried about traveling once I'm in South America as it will generally be overground.
I will be departing from London and would like to start my adventure in Caracas, Venezuala. But then again I could start my travels in Colombia or Brazil since I'm just looping clockwise around the continent. I actually want to end up in California and go through Central America, perhaps returning from LA. How do you plan ahead for flights like this? I'm very flexible and open to tips; mainly I want to save money where possible and can change my plans to suit as nothing is set in stone as of yet. I'm happy to make stop-overs and happy with any advice since I don't know how to go about doing this.
