My trouble was also with kayak. I put in to your search engine the dates, times, cabin and amount of luggage that was needed. When arriving at the airport we were charged $280 extra. I have booked thru Kayak for years. Never have I encountered such a mistake. The entertainment was below average. The food terrible. The check in outrageously slow and the complaints continue to add up!

Great customer service both on and off the airplane. Flight was very comfortable. Thank-you!

I had booked my wife and I on AR from BUE to MIA on January 10th and secured seats 6A and 6B. When I checked in AR claimed one ticket was booked for the 10th and one for the 11th. They forced me to by a new ticket and charged me an additional $2,400.00 USD. I want a refund. Rob Austin

I tried to add checked baggage through the website; the amount was charged, but the payment was not linked to my reservation. As a result, I had to pay again at the airport and only received a refund three weeks later, thanks to my bank’s intervention. The flight was delayed, and the boarding process was poorly organized. Several boarding groups were in the same line, which made boarding very uncomfortable. The food was acceptable, but the beverage service was limited. While drinks were available at the back of the plane, it would be better to offer more beverages during the meal service. On a positive note, the cabin crew was very kind and professional, and we arrived on time according to the revised schedule.

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

Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

There was a mechanical issue with the plane that they had to work on before we could take off. That's fine, by all means, PLEASE make sure the mechanics are functioning properly. What was a problem was the fact that we sat on the tarmac for 4.5 hours without moving, without letting us off the plane, and without climate control and air running through the plane. There was no explanation as to what was going on; they just kept promising that it would be "15 minutes, then we are on our way." At one point, they even switched the entire crew out and told everyone we just needed to wait for new employees to show up. Then, as the 4 hours were not moving, an hour before the full refund, they made a big show about "the flight starting and the doors are locked, so you have to sit down." We didn't move for another 40 minutes; they were just trying to skirt around legalities that entitled us to restitution. When the flight finally was underway, the plane was gigantic but cramped in design, my entertainment screen kept freezing and glitching, and subtitles didn't work, and the crew was passive-aggressive. Terrible flight.

LATAM’s crews are fine, but God help you if you need any customer service. Their app and website never work, with error after error. Trying to solve anything over the phone is painful, and lastly, the boarding pass LATAM gave me to board the flight with Delta was invalid and I had to purchase an emergency one-way ticket at the last minute to get home.

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

The assistance we received and the flight itself was wonderful. We will fly with LATAM airlines again, in the future.

Latam may be the worst airline in the world, far worse than even the lowest of low cost airlines in the USA. I wasted hours trying to PAY THEM TO CHECK A BAG! Then they misled me at the terminal, sent me through the wrong security line, the list goes on and on... Just absolutely terrible in every way. Avoid at all costs.

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 .
