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

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 was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

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.

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

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.

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

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

Lost ,y connection due to a mechanical delay, huge line to get new connection and vouchers

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.

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)

Seats not reclining, no vegetarian food option, no snacks. 7.5 hr flight should have been more comfortable. Luggage limits are unusually small. Will never fly Copa again and will tell friends and family to avoid this airline.

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

Tell people to remain in their seats during the meal/beverage distribution. Enforce boarding by group numbers. No one was checking. Tell people to turn their electronics speakers off. Bigger cups for drinks.

We flew with Avianca, some how they are not n sync, making the process a bit uncomfortable.

Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.

Flight on time, check in and flight attendants courteous and helpful. Smaller plane for international flights, tight space, no comfortable.

the boarding staff were incredibly officious. our carry-on case was borderline within dimensions but staff were not prepared to show ANY flexibility even though many others with larger carry-on luggage were allowed to board. we were understandably furious but the staff were incredibly disrespectful. we called the supervisor who eventually agreed to look on board the plane to see if there was room for our case (one case between 2 of us) and reluctantly agreed to allow us on. The staff on board were excellent though and realized we had been treated badly and were very helpful both in finding a place for our case, some distance from our seats, and helping us to retrieve it when we landed. We are regular travelers on Gol and have Diamante status and had chosen the better Conforto + seats, so we expected better treatment from the ground staff. Also the cabins are of a size that will only fit 3 cases of normal size with a large gap of about 30cm of wasted space. If our case were deemed to be oversize, which I dispute, the extra 1cm would not have made the slightest difference.

I did not like the way that baggage fees were charged. When I signed up for the flight, I knew that there were bag fees. However, the bag fees were so confusing that it felt like I was paying for overweight bags rather than just for having brought a bag with me. Also, the bag fees were based on the pair of tickets rather than per person. It seems to me that it should be first bag fee for passenger 1 and then first bag fee for passenger 2. I eventually got away with only paying $100 for two bags, but it was a struggle to understand the process. As for the flight, the seats were the standard uncomfortable seats that are on most Boeing aircraft. The airline aims to accommodate the standard height people, so us tall people are stuck. There was never an option to upgrade for leg room. It did not appear that there were any seats on the whole plane that had a little more leg room to even try to get. Other than that, I completely ignored the food for this red eye flight. I am not one to eat "dinner" at 2 am. They did not offer any drinks in the morning before landing. I recommend that you bring a bottle of water on board.

Lost luggage, people are not very nice to help you , I was just instructed to fill out a baggage claim online, they were not helpful when I had additional questions after I completed the form on my phone.

They are not ready for international flights, poor service and food, no screen info on the seat.

Horrible. I was never able to board the e flight as they had a glitch in their system that didn’t showed me as a passenger. I waited 2 hours at the front desk till they closed the flight, and they were not able to board me in it. They didn’t offer any sort of solution or refund. Such a disappointment. I would never flight with them again.

It was really bad. Inexperienced and rude people during check-in in Miami, a small and uncomfortable airplane, and problems with the airline caused me to lose my connection flight in Brasilia. Terrible experience!

Pretty terrible, was unable to check out of a flight through the app. Could not check in to my flights with the app. Had to call customer service but they were not much help. Nothing on my itinerary said I had to check in with American Airlines when I reached the United States. I almost missed my flight. I had to run to the gate and get dressed in the tunnel. GOL seemed really unorganized at the desks for check in and took a lot longer than other airlines

Internet was a bit expensive and did not work ask that week otherwise a good flight

Ring in first class for an overnight flight, there was no blankets nor pillows for first class customers.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Pretty good. The food was just mediocre, the boarding and crew were good.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.
