I am flying on the 25th Feb to Santiago in Chile. On the 28th, I would like to fly from Santiago to Cuzco. Any good tips? Thanks. I have been on www.despegar.com to check tickets, it is a travel agency. Does anybody know if it is a serious travel agency, or is there any better option to book a ticket online? Alternatively, is it better to buy the ticket once in Chile at the travel agency? All answers are welcome. Thank you in advance.
