Booking class 'O' for SCL-IPC?
 

I'm exploring the idea of visiting Easter Island next April, and was using ITA Matrix to play around with fares. For many dates, the system gives me a return fare of ~US$330 for SCL-IPC, which I understand is really low. And the thing is, I can't find anywhere online, not even LAN's Chile site, that can give me this fare. They all quote the standard ~US$500.

I guess this is due to the booking class 'O' for this fare. Anything special about it? Can I go to a travel agent to book this?

Sometimes inventory appears on Matrix which cannot be booked anywhere. This happens quite often with LAN I am afraid. You used to be able to book anything on Matrix via AA.com (at least for OneWorld flights) Worth a try but I think that might have changed too
