Does anyone know a great travel sight for buying cheap plane tickets to Santiago, Chile?

Any of the travel sights such as Travelocity, Expedia, etc. are all about the same and may charge you a small fee for you ticket.

Sometimes you can get a better deal by buying direct from the airline. They usually do not charge you an extra fee on top of the ticket.

Depends from where! Plus they are GOING up!!!!

use first:

www.kayak.com then

www.farecompare.com then

www.orbitz.com and to benchmark

www.cheapoair.com

from Canada, Toronto (YYZ) AirCanada

from Miami:
USD758 with COPA

from NYC:
USD 836 with Avianca

other option:
Spirit Airlines to Lima, Peru from FLL/Fort Lauderdale, very inexpensive then a USD150 R/T ticket with Lan Chile/Lan Peru from LIM to SCL/Santiago.

There is a chilean travel agency which operates flights from anywhere in the US to Chile. It's called Keka's travel (www.kekastravel.cl) and you will find cheap tickets to anyplace in Chile. Try it, they specialize in bringing americans to Chile.

Well, as a travel agent and the fact that I was born in Chile. I can tell you, the best way to go is buying from a whole seller the bad thing is they don't usually sell to passengers, but to travel agencies. Of course that agency will make a profit. I will try www.lanchile.com if you are flexible with your dates if not try www.kekastravel.cl I know they have a contract with some airlines.
In any case try to fly with Lan Chile is far the best airline. I got my tickets on April for 725 all taxes included, direct flight with Lan. Good luck . Chile is marvelous.

Strange as it may sound, of all major airline travel sites, I have found that the cheapest fares (for example in September) were with Delta airlines - followed by American - only then LAN Chile.

I'm a travel agent at Beeline travel so if you need a trip there send me a mail to southamerica_travel_expert@yahoo.com
I will answer your questions.

Depends from where you're flying, I flew a couple of months ago with AirFrance from Europe and it was the cheapest deal back then. Since it's not the most popular destination the prices are more or less the same, no matter where you buy the tickets.

If you go to www.sidestep.com, they search multiple travel sites for you to give you the lowest price.

im traveling from chile to the us all year long and id say lan (lan.com) is the cheapest way to get to chile. aa is charging like $800 these days to miami and copa, which is from panama, is way too expensive and i wouldnt fly that just as i wouldnt fly aeroflot from russia EVER.
