We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

My flight delayed and i misss the connection they send me to orlando no to tampa i have to pay a uber to my house

It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

No headphones given for inflight entertainment. I missed my flight from the previous day and the customer service agent tried to extort an additional $100.00 US from me for missing my flight. Really?!

It was reasonably comfortable trip considering its duration (7 hours). Crew was very good and friendly, seats very more comfortable than other planes. Only negative comment would be that the bathroom light did not get its full brightness 🙃

The flight was delayed about 4 hours without any explanation. No wifi or entertainment at all on planes. Had to pay for checked bags I was allowed according to reservations.

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

Friendly flight team and seamless travel from one stop to next.

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Great flight. Departed early, arrived early. However they were out of meals for sale. Also, we arrived early and the gate was not available so we sat on the taxiway for quite a while (not JetBlue’s fault).

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

The inflight system with their wifi is a hot mess and doesn't work. Separately they do, but when you try to do theoretically simple things like pair a device for control it all falls apart

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

I like their airplanes because they have plenty of legroom in their seats they always work with me if I have a change of plans on my tickets courteous and I always feel safe flying with them.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.
