Am I right assuming that any flight booked now with travel dates before December can be re-booked for some time between March and May next year without fees?
Thus, I could book now for November 2020 and move to next year before ticketed date. If things do not improve until then they may even open more time next year.
Here is what i found at Latam's website:
