What's up Scott, it's the other Scottie at Rocky's. You are right about the JetBlue thing. Unless you are staying in Santiago and don't mind flying in the middle of the night then stay with them. The 30 bucks you save will be easily spent on a taxi, bus or rental not mentioning the time and danger of traveling through the "cumbre". BUT AA is the best bet, within a half hour after getting out of the airport you are on the beach. YOU CANNOT BEAT that anywhere.
