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.

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible
