Airline reviews

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

landed in panama it was in terminal one. We had to take a bus to terminal two for customs. Then back to terminal one. It was very frustrating. Then, on the way back from panama it was the same situation. We had to go back and forth between terminals to check in and drop our bags and then to board. When we were leaving, we had to wait in line for the boarding area and go through another gate security process. They told the bottles of water and coffee were bought while in line in the airport after we passed the main security. Ridiculous (and expensive). A much better communication system is needed.

This was my first time flying Copa but I'll definitely be back! Great service, professional agents, and delicious food for a fair price. Thanks for a great trip!

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.

Cons: "Sure. I had booked a two week vacation in Brazil. All hotels, car rental and guides booked. Copa changed my fligjt at the last minute and out of the 14 days vacatipn I had in Brazil, they would have me spend 6 days in Panama City!!! Lost of small fortune with hotels, car rentals amd had to buy another ticket with Latam. They are a scam!!"
Cons: "Due the COVID-19 El Salvador closed its boarders, leaving me unable to fly. I have sent two emails, called and spoke to a customer service representative who treated me unprofessionally and rude. After that I have been calling numerous times with a wait of over 25 minutes each time and I still have to answer from you as a company. I am extremely disappointed and want an answer soon."
Pros: "Crew was great. Food was acceptable. Really comfortable flight."
Cons: "Entertainment could have been better. Tvs per seat to wAtch movies what we want"
Pros: "nice crew."
Cons: "seats were too small and uncomfortable, not possible to lean back much because of a tall passenger behind me. international flights should have better seats."

I was shocked flying to El Salvador that they only give you water. Everything else you have to pay for. There is no wifi or entertainment and it’s an international flight. At least back in the day they had tvs on the plane and everyone watched the same movie. Also seats do not recline, even comfort or plus.

I did not like anything, first time I use company and for sure it will be the last time, they charge for simple operations that any other average airline wouldn't charge.

The good thing is the flight was on time and the crew was really nice. They can work better the arriving with staff

The inflight entertainment did not work on a 6 hour flight The cel phone chargers did not work There was a 45 minute wait for the luggage to get off the plane.

Seat space was terrible no food on a six hour flight

There was no bag included in the reservation. The price was double. Not properly advertised

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

They could offer free food and drink like other international flights.

Flight attendants to show up on time, offer drinks and food.

The worst airline, the crew so mean and rude, everything was a nightmare, if I start to write, I'll never end

The flight was one hour late. The food is mediocre and the screen was broken

Flight was smooth but unnecessary long because we had to refuel at FCO Rome. Air hostesses service and response to call light could be better. Both planes were old with broken seat arms and toilets. Why Africans had to be given the farthest Gates is what baffles me and why we have to pay for Aisle seats I found really strange. Is there ever an end to ripping people off even after paying over $2300 for one seat.

it was a nice tripe but they need to work on the serving of soda,they should be abled to serve cain soda not on cup.At least each passenger should be entitled to one cain of soda not serving on cup.thanks.

On my return flight the TV did not work the entire flight! They knew it wasn’t working but they let me sit there. The guy sitting nièce to me told me he was ok the previous flight and it wasn’t working. This is business class by the way!

The entertainment (movies) blockbuster and classics never change. I am a frequent Ethiopian flyer and this should be addressed. Not much changed from my summer flight and my December flight. It is annoying - surely you can update the selections more often. Same with food options. It becomes extremely boring to be offered the same exact meals from Washington to Addis to Maputo every trip, each time. AS

Entertainment was very poor. Couldn’t watch anything. Ear pieces were the wrong type .

Food was horrible. Our flight was not comfortable due to turbulence, seats was not comfortable, Very tight barely can not move anywhere.

The check in staff was amazing. Best customer service! The plane was old! My entertainment on the first flight didn't work at all, in my seat or in the seat next to me. The bathroom doors were old and troublesome. One of the bathrooms, the whole sink panel was broken. Everything felt old and falling apart. The airline stewardesses were amazing and quite hospitable. When there were delays, they kept us well informed. Transit was GREAT! I wasn't sure how I would make it to my next flight in 1 1/2 hours but the security lines were short and efficient. The C gates in Addis Ababa were CROWDED! That whole space downstairs was too crowded and challenging to manuever. I usually fly Ethiopian within Africa and was interested to see how the experience would be intercontinental. Overall, I would choose it again if it was cheaper than Delta/Air France or Lufthansa/KLM. I wouldn't make it a first choice if the prices were the same because the planes are so old! The food and entertainment also weren't as good. Good selection of movies but as I mentioned, on the first flight they didn't work at all (I slept so it was okay) and the 2nd flight it was glitchy. All in all, I didn't hate it but it would be a first choice only if it's cheaper.

The food really sucks And they really need to work on entertainment The movie selection is herendous .

Hot, uncomfortable and very rough take off and landing. Very regrettable.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

The plane was old and in new of a cleaning up and renovating on the interior. Seats and carpets were very worn and dirty looking. Cushioning on the seats was broken down and not as comfortable as newer jet seats. Food was a little below average but okay. Staff were friendly and hard working but did not pick up debris or food they spilled when collecting from the customers. But they were very helpful and professional.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints
