stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

Some of the Air hostesses are not that friendly. Need improvement

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Great experience with a crew always thinking in the passenger

Had to go through security at the gate again. Had to take off shoes and go through the whole thing again even though we have global entry. They asked us to check in items bought at duty free during our layover and since we checked our luggage at the original departure airport, they forced us to check in a small backpack. None of this ever happened with other airlines. In addition, no vegetarian food option and no snacks during a 7 hr flight. Luggage limits are unusually small. This is unacceptable. Will NEVER fly Copa again and will tell friends and family to avoid this airline.
