We are from Boston. Recently we bought LATAM business class tickets SCL-IPC (Easter Island) and got row 3 seating assigned.
When we checked in at SCL, we were told that there was no seat for us due to down gauge of 787 to 767 . The check in agent blamed that we didn't check in online to get boarding pass ?! In the end, we only got coach seats since we already paid non-refundable hotel cost at Easter Island.
LATAM never informed us this in advance and the agent at SCL wasn't much helpful. He said that the compensation was $300 voucher or $150 cash and refused to increase this amount.
This is my first time flying LATAM. What recourse do we have? What are the rules or laws governing involuntary downgrade?
Could any veteran flyers of this airline offer some insights?
