When I travelled to Machu Picchu a few years ago I was able to save a lot of money by bying internal Peru tickets from the Lan Peru site. I just did a trial and again if I go to the Lan Chile site the Easter Island tickets are cheaper then the Lan - US site. Has anyone done this recently and had difficulties? A few years ago there were def. complications in paying which a credit card but knowledgable trip advisor people had pointed out the potential pitfalls before I attempted. Thus I was able to eventually navigate through it. I remember one category (the cheapest) being only available for Peruvian residents. Without the TA forum I would have bought the wrong tickets. Any advice or direction would help.
