On the trip to Rosario, we raw dogged it for 7 hours. No wifi, no charging outlets, Gilbert girls on every third row monitor with no audio. It was better on the return flight—at least we had screens and earplugs.

I would like a glass of wine or some kind of alcoholic drink.

Boarding groups were called up in Spanish only. Luckily I know some of the language. They gave out grilled cheese sandwiches and a cup of fruit. I was very disappointed. I could only eat the cup of fruit because the only other option was vanilla pudding. The entertainment system and seating were great though.

The flight was 6 hours delayed due to equipment problems, I had to spend my night in the airport terminal in tight quarters. A bag of chips was all they offered, Then I missed my connecting flight and waited another 2 hours. All in all that trip took me almost one day.

it was great! Boarded on-time, reasonable leg room, pleasant staff, decent food. The only thing is we were directed to Terminal 2 when the gate was actually in Terminal 1. Smooth ride. Landed early. Got off plane easily and quickly.

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

So many hours of flying without salty food is a shame and the fact that they want to sell it to you seems like a rip-off

This airline makes you check in in one terminal and then you have to walk to the other terminal. Its messed up

Copa delayed the fight three times. We ended up flying about 24 hours after the original time.

We boarded so late it caused us to miss time at Foz. No real information was provided to the passengers waiting.

reliable, relatively relaxed, helpful and kind staff and clean airplanes. No need for more.

reliable, relatively relaxed, with helpful staff in all 8 flights we had on this trip. They are solid even though we did not have special seating or status for the flights.

Only complaint is that the entertainment system wasn’t working on our seats and some others.

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

Airline changed our itinerary several times (3). The second time, we were not aware of it, we landed at 7:24 pm and the flight depart time was 7:40 pm. We were not aware of this change and the flight departed without us, that made us being placed on an even later flight which was also delayed.

It was fine. no food or entertainment , but was only a 40 minute flight.

Paper boarding passes needed, so you need to add the time at the kiosk or desk to get them at the airport

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta
