Terrible experience.

- LATAM app/website is not giving an option to choose any seat for free (FF# was added). Called LATAM call center, was told “you need to do it in the airport, no chance to do it in advance in our system”.
- LATAM app/website wants to charge you for a luggage ($90 for a first pc); call center was unable to confirm until the very last moment, will 1 peace of luggage will be free or not as for DL Diamond. Told me to call Delta 🤯
- 24 hrs before the flight. During the check in, system gave me the worst seat (the very last row in the middle) despite it was a lot free seats on the screen - but any manual change need be paid. One more call to LATAM - was told “check in staff in JFK will change it for you, we can not”.
- On a check in in JFK they took 1 suitcase for free (bingo). But flight was full, so - “keep the seat which you already have”.
- Same story before the flight from GRU.
No chance to choose the seat in advance for free. No chance to change the bad seat in the airport - as flight is full. The only benefit - they check the luggage in a separate room for their top tier frequent flyers,
the entrance is from the street, you are not going to the lane inside the airport.
Denied to check the luggage to my final destination (short connection, separate PNR with DL from JFK).

It seems like just one useful benefit DL Diamond status can give you while flying LATAM is free peace of luggage and a check in on a business desk in JFK and in a special booth in GRU. Seat selection does not work; no one has any information in advance 😳
