Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

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

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

I selected first class expecting excetional service. It was mediocre at best. The food service was cold, meal choices was poor and on one leg they did provide dessert. I did enjoy the lay day seat but the movies were old and nothing current. Boarding the plane is always hot. So boarding is quite warm until your in the air. I took a small personal air fan. Update the meals and movies.

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.

Seats not reclining, no vegetarian food option, no snacks. 7.5 hr flight should have been more comfortable. Luggage limits are unusually small. Will never fly Copa again and will tell friends and family to avoid this airline.

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

We had a five hour layover in the way home from Colombia. I read the "bout your flight" email carefully before we checked bags. We had to go through security right at the gate. Almost lost our ground coffee because that airport only allows 16 ounce of coffee and we had 18. I've been to 48 countries and never heard of a coffee restriction. I can't follow a rule I don't know about. I requested they bring our coffee to our checked luggage. Instead tey gate checked our bag for free. Back to planning transfers in Dallas I guess
