Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

I didn’t not like that I could not select my seat and ended up with the worse seat.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

Please see my lengthy description on MSP to Atlanta survey. Tailbone is killing me from old hard seats. Seat would not recline and were not near exit row. Entertainment did not work properly and couldn’t use. No audio and touch screen failed. 3 plus hours of discomfort in narrower seats than previous flight not in comfort plus. Very dissatisfied and deserve comfort plus charges refunds, at the very least, for both my wife and I. The plane needs to be retired. Please feel free to contact me directly for further details.

MSP to Atlanta was much better than Atlanta to St. Kitts. Paid $180 each for myself and wife for Delta comfort from Atlanta to St. Kitts. Seats were more narrow and obviously old and worn out. Tailbone is killing me. Seat would not recline. Seats behind reclined and we were not an exit row or in front of an exit row. Entertainment did not work in that the movie jumped forward and back and there was no audio. The plug in the arm rest was loose. Flight attendant tried “resetting” the video for my seat but no good. She never checked back. Someone else near me had the same issue. Touch screen was unresponsive. No where near as comfortable as MSP to Atlanta flight. 3 plus hrs. flight time without the basic amenities and not even remotely close to comfortable but paid for Comfort plus. I will be very disappointed if I have the same on my return “Comfort Plus” flight St. Kitts to Atlanta. At the very least my wife and I should be refunded for round trip “Comfort Plus” charges. Please feel free to contact me directly for more details.

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Pros: "The crew was very interested on help and attentive with the passengers. But the seat wasn't comfortable. The design of the cushion is not the best to be seating"
Pros: "You were on time, that is the most important thing in a fly"
Cons: "You could improve your entertainment, you are not a cheap company"
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"
Pros: "Copa was convenient and easy. Very easy boarding process and I appreciated the day flight."
Cons: "This is a business class that is equivalent to a US carrier domestic first class. Good seats, not lay flat but wide on my 737-800. The food and service emulated say American Airlines Domestic 1C as well. Everything was just good enough, and much cheaper that international business on the majors."

Everything was as you would expect in coach - fine. Flight was close to on time.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

Horrific checkin procedure with neither Delta nor Latam figuring out how to check me in. 4 hrs on customer support with both and both airlines pointing to each other who should do checking. I was not checked in until morning of flight, which for international flight is concerning.

It was a good experience, the flight was a little too long & the food was ok

the flight from Boston to Curitiba was on time actually 30 minutes earlier. latam was not able to unload the luggage for custom checkup in Sao Paulo ii took two and half hours . i missed the flight to Curitiba spend the night in hotel and then flying in the morning to Curitiba

Tough flight with turbulence… I was told by a fellow passenger that it is common. Nonetheless, very stressful. Cordial staff.

Very unprofessional staff in the checking and boarding. There was no space for my carry-on bag, which is understandable for a full flight. However, the rudeness in answering my questions about my bag were unnecessary. Shaming and threatening a passenger to be left behind was something I had never experienced (I am 57 years old and a Skymiles member) before. At a minimum, the boarding staff (Krystal Mejia and her manager Dee) should undergo further training on cultural sensitivity and professional skills on speaking with passengers. Krystal, just because I have dark hair and “look Latina” does not mean I can speak Spanish. Your assumption and threatening words until the very ending of my boarding (door of the airplane) were not only unnecessary and stressful but something that a passenger should not experience before boarding.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..

The flight from PDX to New York was cancelled, and I got rebooked one day later. Because of this I missed a meeting at my final destination, EZE. I now need to stay longer in Argentina, and was told the tariff difference was $780 plus $150 penalty! I am not using my return ticket, and have purchased a one way ticket EZE-PDX for $606 with another airline. SHAMEFUL

Cons: "The flight was full and all seats were taken. It means it was impossible to maintain the required and necessary social distancing."

Very bad. Boarding was a caos and pick up luggage took more than an hour. There was no entertainment on board.

La aeronave estaba averiada, 4 horas adentro con diferentes problemas técnicos pero igual querían volar.

Evifente que o melhor seria a Hol cumprir com ssua parte! Vendeu voo dirto Caxias do Sul a Florianópolis e depois alterou, fizemos voo Cxs. Congonhas, com conexão, alem de um atrazo, mais de 1:20 min. Está errado e isso é vender uma coisa e entregar outra...

The plane was fine and the crew was very nice. Even though we bought our tickets eight months in advance and had seats reserved, they changed our seats. Instead of being in seats 7E and 7F, we were separated and put in two middle seats away from each other. When checking in, the attendant put us in an exit row together, but 10 rows back from where we had reserved. But you have to be younger than 60 to be in an exit row. So when everyone else boarded we were moved to last row 33, right next to bathrooms.

Fiquei de pé um tempão para embarcar. Apesar de ser grupo 1 e ter prioridade e cadeira premium.Ficamos retidoa e os outros grupos entraram antes... Vai entender este método uruguaio de embarque. Voo sem internet e tv. Voo em aviões mais velhos da gol que tem esta facilodade. Economia??? Pior foi o desembarque. De ônibus e vários fingers libres, vai entender

Alimentação mto escassa. Pelo menos deveria dar a opção de comprar e o Wi-Fi pago.

A Gol precisa aprender comfazer desembarque. Está anos luz atrás em organização. Os comissários são muito atrapalhados.

Os passageiros ainda não estão habituados a respeitar o embarque por grupos, que é a melhor maneira de embarque, na minha opinião. Então faltou pulso para impor a regra de embarque e desembarque às pessoas.

Kiwi service was terrible they actually didnt make the reservation and their system showed that the reservation eas complete so I had to buy a ticket in the front desk at the moment at and exorbitant price.

A Gol melhorou muito desde a última viagem que fiz, muito bom, aeronaves bem conservadas, tripulação cordial. Gostei.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

The flight was 6 hr late and then they blamed it on the weather. All of the other planes were coming and going fine.

Overall okay. Ipgrades ate worthless anymore. Wish I’d not been so loyal To them for so many years. Platinum many years. Gold for life. Usually 20th-30th on upgrade list.

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

Our gate number was changed but nobody alerted us until we tried to board the wrong flight then they told us almost missed another flight. Very bad service.

The flight attended didn't ask one everyone in our party if they wanted a drink or snack. The one attended appeared to hate her job which is the one that attended to us.

Flight was delayed, I tried to leave 2days earlier was told to report to airport for standby only to be turned away after paying for an Uber both way from Little Elm TX.
