Looks like they are canceling ticketed flight rolling 60 days ahead offering rebooking or travel vouchers only (which to be fair appear to be transferable to a personal bank account).
No proactive information from LATAM whatsoever, had to "discover" myself the cancelation.

As per this https://farsouthexp.com/chile-is-slo...-again-240721/ interesting source, the country (not Rapa Nui) could reopen to tourists early October 2021, but I am not too confident that this will be without quarantine.

As per today 79.5% of the eligible population of Chile vaccinated tough.
