Airline reviews

The seats had plenty of leg room and the staff were very nice.

8.0 ExcellentAnonymous, May 2024LAX - PTY
Read more about Copa Airlines reviews

The seats had plenty of leg room and the staff were very nice.

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!!"

Very bad organization to accommodate over compartment inside the main cabin. Crew was not helpful at all!

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.

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.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

The flight was delayed almost 2 hours. Bad customer service etc. I will never fly Luthansa. Ever!!!

On time take off…US cabins look tired and need of refresh!

Fine. Though no food or entertainment so the survey needs to be updated with those options.
