Obviously no way to know for sure what will happen.

But what is general consensus/thoughts if Easter Island will be reopen to travelers by June 2022? Also, is it thought flights will resume from PPT as well as Santiago when they do resume?

Like others, I had a combined Business Class Award trip to PPT / IPC in August 2020. AA miles on partners ATN and LATAM respectively. Loosing the trip was a double blow for me, as LATAM now no longer partners with American.

My French Polynesia portion of the cancelled trip is currently rescheduled for May 2022. If the IPC flights seem favorable for resuming before June, I'd look at possibility of putting a placeholder flight in place from SCL back to the US, and purchasing the Easter Island flights (PPT-IPC-SCL) when they become available. Assuming those flights aren't initially priced completely out of my ballpark when they resume again.
