Hey everyone, this is my first post, so please forgive me if I've missed a thread where this was already discussed.

I'm planning to fly into SCL from ATL in the fall, spend 6 days and then fly to EZE for 5 and then back to ATL from EZE (all via DL). However, I've been on Orbitz looking to book a one-way flight from SCL to EZE, and all of the directs seem really expensive.

AC has one flight on the day I want to leave for $353, which is way cheaper than LAN has for around $580. I would be fine booking the AC flight, but I'm worried since they only have one flight every other day that I could potentially be stuck if the flight were cancelled.

Does anyone have any recommendations for best thing to do? This 2 hr. flight is the only thing causing me to delay booking the rest of the trip.

Thanks in advance for your help.
