This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I’m entitled to a refund per LATAM due to the mid flight itinerary change and being stuck in São Paulo for 24 hours and needing to get a hotel. The airline was dismissive and of no help.

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

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

My biggest complaint is the comfort. I am not tall and there was no legroom. It was very uncomfortable. During my transfer in Sao Paola, the flight was slightly delayed so boarding was confusing because there were no instructions in English.

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

I never got this flight. You sent me to Chile!!! And from Chile I got the other flight to São Paulo... I've arrived 7h latter than I was supposed to arrive because of Delta delays.

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

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

Wider seats, better seat cushions, (I felt like there was a board I was sitting on). I had the chicken to eat but It neither tasted nor looked like chicken. The fruit was good.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

horrible service, food was an embarrassment, no charging for cellphones, stay away

the food served was an embarrassment. No connection for charging the cellphone... What a crappy airline.

Great experience with a crew always thinking in the passenger

I selected first class expecting excetional service. It was mediocre at best. The food service was cold, meal choices was poor and on one leg they did provide dessert. I did enjoy the lay day seat but the movies were old and nothing current. Boarding the plane is always hot. So boarding is quite warm until your in the air. I took a small personal air fan. Update the meals and movies.

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

We had a five hour layover in the way home from Colombia. I read the "bout your flight" email carefully before we checked bags. We had to go through security right at the gate. Almost lost our ground coffee because that airport only allows 16 ounce of coffee and we had 18. I've been to 48 countries and never heard of a coffee restriction. I can't follow a rule I don't know about. I requested they bring our coffee to our checked luggage. Instead tey gate checked our bag for free. Back to planning transfers in Dallas I guess

Placed us in the last rear row of the plane so could not recline seats because of the rear wall, and also made it more of a tight space when the passenger in front reclined their seat. While understand seat assignments, every passenger should be afforded a reclining seat. The odor control scent from the restrooms was overwhelming strong. My wife and I could not deal with it, and she suffered a terrible headache as a result. I kept getting hit by the crew since I was on the ilse seat. No apologies, nothing. They made me feel like I was supposed to take the beating for a 3 hr flight.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

We were given vouchers we couldn’t use with a 5.5 hour delay

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

Boarding was excessively slow. They do it by groups in a way that it doesn’t make sense. After business class , ppl that need assistance and any other priority group they should have ppl board from the back to the front. First rows 20+. Then 15+. Then 10, etc. having ppl sitting in the back board last makes no sense. The libe backame long as soon as ppl on rows 10 or so where told to board. The line went all the way up the ramp and tunnel for 25 mins.

Seats are very tight even in Plus, no complimentary snacks or beverage

I receive a service for what I pay, so it is fair.

Excellent flight and one of the smoothest landing I’ve ever experienced

There isn't much space in-between seats and even water needs to be paid for during the flight.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.
