Hi all,
I have an upcoming itinerary to Rapa Nui. The flights are JFK-SCL-IPC all on one ticket. I know there are some extra check in requirements for those on flights to Rapa Nui. I was wondering if they do these extra steps when I check in at JFK or do they all have to be done in Santiago.

I see that Latam recommends checking in 4 hours in advance and the itinerary they sold has a shorter connection time in Santiago than that. So, just wondering what to expect.

Thanks for any insight.
