Good trip, excellent attention. I like Copa Airlines, the best. 👍🏻

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

I would enjoy a glass of wine on such a long flight.

Everything was smooth and crew was very polite and friendly.

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

Crew were all excellent. Wheel chair access for my parents was very good, although it took some time. Plane was ok but entertainment system did not work. NO WIFI on plane so could not get other things done while flying or listen to my Apple Music on my iPhone.

I like that they served a mail, I’m not sure about the in-flight entertainment. I didn’t really check. staff helped me with my luggage. Smooth boarding smooth takeoff smooth flight

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
