Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

Seats comfortable, service and food very mediocre, staff not very attentive, worse than many other our flights with Delta.

Overall good experience; however, there was one flight attendant who was rather rough compared to everyone else. Everything else was good: entertainment, food. Delta keeps on delivering! Thank you!

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Crew blocked exits to front of ship with galley carts. Also split five person family apart on international flight without fixing.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

The way the Pilot made all announcements, specially the way he congratulated the entire crew as the best team ever, making a comment that due to them they were able to shorter the delay to the destination. Amazing flight .

we were missing our luggage, trying to find someone to have any empathy was pretty much not happening....

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

The flight was late. Please do not delay next time.

Horrible the worst airlines I have ever flown. Cancelled flight with no choices and when contacted them they were not helpful

Because the flight was late, we lost the connection to Brazil. You, Delta delayed, and you Delta anticipated the door closing in 15 min from Miami to GRU. Why? It caused a lot of stress! I almost could not see my mother in law alive because of your delay.

My entertainment did not work. I was very tired from the botched connection, and the poor sleep

It’s a delta flight operated by LATAM. The whole ticket sale is a mess, delta changed my flight but didn’t update it in LATAM system, I couldn’t get my boarding pass, it took me hours to resolve this issue with delta. I had to change my travel plan. No apology from Delta even though it’s their fault.

Boarding was done by woman who insisted on strict standing in line policy; food was ok; entertainment minimal

entertainment was not good; the shoulder strap on Business class seat did not sit well across the body (more like across the neck); the food was not hot and the special meal promoted by insert in the menu was not available to us
