The check in staff were so friendly and accomodating. Loved it. very rarefly you find that in other airlines.

Boarding was uncomfortable. Groups weren't boarding in an orderly fashion because everyone was taking to buses together. It was 90 degrees, but there was no air-conditioning. We left 40 minutes late without explanation. Uncomfortable!

Outstanding service both from ground staff and onboard staff! Very helpful in making changes to our schedule when our trip ended sooner then expected

They changed the flight and the airport on both legs of my flight which made it impossible to actually make the connection from one airport to the other in time. However the customer service agent at the international airport was very kind and helpful getting me on a flight for the next morning.

We were delightfully surprised with the exceptional ground staff as well as flight staff. Both did an excellent job of making our trip enjoyable and hassle free!

Please work on delays. This airline always has delays. The terminal is awful, aeroparque needs more transport for disabled people (terrible service), and proper equipment to deplane. It is the only place where I always have to use stairs

I flew in a new plane with an excellent crew.Felt great

My experience was TERRIBLE. They made me check my carry on bag, and they broke it. and then when I made the claim they said it was a small damage and that I would not be compensated.

Despite asking several times why our flight wasn’t on the boards, it took us a while to figure out that our departing flight was from another airport. While the tickets clearly indicated that we arrived at AEP and left from EZE, none of the aerolineas argentinas personnel noticed it despite specific questions from us. It took a sharp-eyed passport control person to notice it the second time I tried to go through security after exiting to try again to figure out what was going on. Also the what’s app is only in Spanish and when I tried to type Spanish from an English phone, it would mess up the Spanish that was already quite rudimentary

Delayed flights and cancelled flights …still waiting to see if the cancellations are refunded

We traveled with two young children, and it was not possible for our family to be seated together. No one offered help or assistance to organize seating so we could sit with our kids. In the end, we managed to find two seats in Economy so I could at least sit with one of them, even though I had originally paid for Comfort+. In summary, I had to downgrade my seat just to be able to sit with one of my children, which was very disappointing

Good flight, boarding ok and crew very nice. Flight was not full so I was able to be very comfortable. Blanket and pillow provided with was good as it was very cold during the flight . Food was very good(small snack sandwich and an excellent piece of orange cake). Overall good flight, no complaints.

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

I like this airline a lot no problems at all, except being forced to check a carry-on bag ., Overall very good airline

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

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

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

Boarding was confusing with a delayed flight because there was no English translation

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.
