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.

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.

Good check in process Poor information on payments at Lima airport

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.

We were not allowed to carry a bottle of water onto the 8 hour flight.

Comfort in exit seat was excellent. FLight crew and flight were excellent. However exit seat tray table was broken so could not use it. Entertainment monitor did not work at all despite attempts to reset it.

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

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

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.

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

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

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

only a bag of chips and a bottle of water in business class was served

Avianca has transitioned from full service legacy airline to "low cost" but has now became a strange hybrid (minimum leg space, started offering business class in domestic flights again, charges passenger for printing boarding pass, etc.). National and international coverage and destinations are really wide but service is not at its best

Provide free food and drinks on an international flight. Add updated head rests

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Horrible experience. Flight cancelled. Arrived at destination 12 hs later. No one gave us an answer or any information. Very very poor service. We won’t ever travel again with Avianca
