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.

It was good, plane is a bit older so seats are somewhat flat

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.

Well the airline was fine. The only thing is I was charged for a checked in luggage. But when I reserved the ticket it showed a check in bag allowed. Who can I get in contact with for reimbursement.? The airline said I had to speak to whoever I booked ticket with.

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

I loved my experience. Very safe, Very informative and very friendly.

At JFK the Security line was extremely long and few checkpoints open.

Check in person said there would be lunch. We were first class passengers and lunch was chips.
