The aircraft knew from advance that the entertainment was not going to be available but you can not even charge your phone/tablet. Food can be a bit more generous

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!

It was delayed for 2 hours. Then when we arrived they took us on a very uncomfortable bus and left us there. The bus driver wouldn't let us out because no one from Latam was there. Everything was disaster.

LATAM is a great airline who takes care of there guests. They consistently walk around and see if you need water in addition to taking care of all the passengers. The chicken in process is really easy and I’m always offered a chance for an upgrade which I appreciate.

Deleted flight made me loose my connection flight now stuck in Atlanta for a day

Apart of Sky miles delta. And they go everywhere in Brazil

On board crew was very good. Crew was friendly, snacks were good, especially the chips. Seats seemed a bit cramped. Boarding seemed unorganized, as we were instructed to get to the gate an hour early and then just stood around until boarding.

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.

First of all, could be Kyak's fault he we couldn't for days check in on line via Kayak or Jet Smart. We can't get the app either. Luckily on LATAM I managed to get the WiFi and contact Jet smart via what's app. This was horrendous and the person was unhelpful to start with. But we explained and she managed to check us in as if she didn't we wouldn't have got on the flight as would've been too late to check in. At the gate they were checking everyone's bag for size. My bag was 1 cm over and they tried to charge me $255 soles to carry it on but was 225 to put it in the hold. We had to pay to put both bags in the hold adding £100 to the cost of the flight. We had to carry the bags as the jet smart sight doesn't allow us to add bags which would've cost us £13 each so £26 on booking instead of £100. Staff at the gate were rude to us and other passengers. I'm sure they were on commission to get money off passengers for the bags. The lady flight attendant was pleasant but over ruled buy this jumped up young guy when I asked if my partner could sit beside me. The plane was 1/3 full. Then he was rude most of the flight. Avoid jet smart at all costs! Worrying thing is we have a return journey with these shower of.... We have been on their site the past two days trying to add bags but site won't do anything. I think this is on purpose to get more money out of passengers. As I said avoid at all costs.

Terrible website. Does not work most of the time I tired using it to check in. Had to have someone from another country help me check in. Their customer service is the worst.

The crew was polite, the Captain specially was cool! But the onboard service was nonexistent: No entertainment, no food, no reclining seats. I know it is a low cost, but the cost of the ticket was not so low for just the transport service.

Was a good flight, no delays and good customer service.

Customer service is horrible. Our flight was at 9pm and we were at check in counter by 7pm. The crew strolls in at 7.30 without even an apology. We were suppose to get our boarding passes online but the website was not working at expected and the staff kept arguing with us saying that is not possible.

There was no entertainment but everyone just used their phones.

The app told us that carry on luggage was included but we were made to pay for it again at the check in counter, making it a very expensive flight. Not happy

I was charged 168 soles for kids stroller. We have travelled across the world and have never charged for the stroller. Horrific airlines and the staff was extremely rude. They wouldn’t let us board unless we pay the extra baggage cost. Never ever flying this airline and I would recommend the same for the others.

Avoid this airline. They are unprofessional. The captain left several passengers on ground due to covid restrictions which were never communicated. As a chilean, I am ashamed that this low level airline comes from my country. Remember this horrible brand and avoid it... Jetsmart
