My great friend of childhood half French half Spanish, Richard, married on March 14 with his Chilean wife, Gloria - on a festoon that I hope to have here some more time although the photos will remain for the author - and at Being married by civilians had no problem giving me their data to buy the ticket that would take me from Santiago to Arica on my way to Peru.
To remove the passage you need to show the identity card although it was not very clear if it had to be mine or Richard's. We took out both of them - I didn't have my passport on me - and the girl chose the Chilean one, although they assured me by phone that all I needed to get the ticket would be the purchase code. Minutes after making the purchase I received the email that told me about the presentation of the identity card, but does not specify whether the traveler or the one registered on the web.
A great advantage was that I did not have to go to the terminal to buy it but also when doing it on the web I got a 10% discount. So if you have friends in the country do not hesitate to ask him this favor. I don't want to remember about 30 hours of bus!
