Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

Horrible experience from start to end. Copa costumer service is non existent. They treat you bad. Everybody tells you different information. We didn’t received our luggage in the 1 day stop we did even we they said if was not going to be a problem. They didn’t respect the seats that we had and spread our family leaving in between of two big people who didn’t leave any space for me and crush me from side to side. I’ll never recommend Copa to anybody.

No cumpli mencionado trayecto por reasignacion de Copa Pero extraviaron mis maletas por su culpa

I was fortunate enough to have an entire row to myself and that was the highlight. Unfortunately, the flight was really turbulent which had no impact on how effective the crew was. However, I am disabled and should have boarded the flight first, but that wasn't the case. They also decided to take my bag at the gate because I had one too many and upon my picking it up at JFK it along with my rollator had been damaged. I am a vegan so the didn't have a proper meal for me and I was unable to view the entertainment because I didn't receive a set of headphones and if I needed to supply my own I wasn't made aware of that either. The crew was great, but overall everything was pretty lackluster.

Pros: "Nothing. This airline is awful in every way imaginable."
Cons: "We booked tickets to Costa Rica with Copa and they just changed our flights to two days later than the booking. They didn’t even bother to inform us of the change we only found out because we booked through Kayak and they let us know. Apparently Copa expects you to frequently check your booking just in case they’ve changed anything and don’t feel the need to inform their customers of any changes they make. Then we were told we could get a Copa voucher to use for other Copa flights for having to cancel our booking and rebook with another airline as a 48 hour change to our flight made flying with Copa not doable for us. But the website kept telling us we had a voucher that was sent to our email but despite repeated attempts it never came through. And spent hours trying to get through to someone on the phone to sort it out with no success ever getting through. My advice. NEVER EVER FLY WITH COPA."
Pros: "Crew was great. Supportive and friendly. Plane was clean and comfortable."
Pros: "No drink because didn’t open de bottle. No one care about it."
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"
Cons: "Some passengers bring two or more big carry ons and the airline should police its own rules better."

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

I like strict carry on policy. Quick to board, quick to leave. Less time at gate and get there quicker

Flight always gets delayed. Sat in the plane for over an hour before take off with no air con, still had to pay full price for snacks/drinks.

Didn’t happen. They stranded us in Orlando and had to book a flight on frontier to get to our destination.

The flight was over two hours delayed from Honduras and over 3 hours delayed from the connecting flight. Ridiculous!!!

Flight left very close to original projected time. Paid for checked bag weight overage (my fault). Plane was literally brand new & this was its 2nd flight. Seats were alittle uncomfortable (I'm 5'11 * 175lbs and was alittle cramped, & brand new seats had little cushion). Food options were good. Main thing was flight took off & landed on time.
