Hi,
how is the rule regarding advance seat reservation for oneworld emeralds and their companions on LATAM flights?

I can't find appropriate information on the LATAM website - just for LANPASS elite members.

The Twitter support team tells me that preferred seating is available for free for emerald and companions - but I can't select preferred seats on the seatmap.
German call center told me that companion must pay for preferred seating, it's only for free for the emerald member.
Then again I was referred to this page https://www.latam.com/en_us/latam-pa...lite-benefits/ and advised to look for Black member benefits as they are equal to oneworld emerald. https://www.latam.com/en_us/latam-pass/favorite-seat/ then says that seating is free for Black and all companions.

I'm very confused ...

Thanks in advance
