I was flying business class, and the French fellow passengers were super noisy. It was not a comfortable flight. And the crew was not helpful.

I was flying business class, and the French fellow passengers were super noisy. It was not a comfortable flight. And the crew was not helpful.

Entire experience from check in to landing was amazing the flight crew was excellent and friendly. Seats were comfortable.

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.

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

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

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

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
