Quick boarding and check in.. but premium seats don’t recline.. very hard to relax. But overall, it was a Great a satisfying experience.. Thank You

If they listen to you especially when there’s a problem with a passport now I lost my tickets and also my seat money

The worst airline I have ever experienced. Terrible customer service. Absolutely disgraceful

Checking bags at the airport, very confusing they make lines for different flights but they don’t have any signs, so if you are on the wrong line be aware they will send you to the end of the correct line. No priority for check in even if you pay and no priority to disabled persons and elderly persons.

Despite all the negative reviews, I took Volaris with a family of 4 (including a toddler and infant in arms). The only compliant was they charged me $70 to gate check our wagon (which we use as a stroller) and then it was not available for pickup at the gate (which is the entire point), so we had to get through customs and the airport with our luggage and no way to push our kids :(

Après avoir manqué l’avion aucune aide de la part des agents à l’aéroport pour trouver un autre vol

Más comida no cobrar tanto por los asientos y comida food

Worst airline ever!! Delays in all my flights!!! Do not flight with Volaris!

The departures screens in the airport showed the flight as canceled for some weird reason, but when I got to the gate just to double check, it showed it as on time, and not canceled. This was confusing, but ultimately I was able to get to where I needed to go.

For whatever reason, when I was in the San Jose airport, the flight from Volaris read as canceled on the Departures screens you'd find all over the terminal, it wasn't until I got to the gate that it showed it as on time and still on. It was confusing, but ultimately I did get to where I needed to go with the flight I was expecting.

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.

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: "Both of my flights were on time which i know sounds basic but all of the flights i’ve catched from SJO to X were late and this time my connection in Panama was only 1h15 and we got there earlier, so that was nice!"
Cons: "A bunch of seats were free and we were mostly sat all together (3 person next to each other).. With the covid situation i think it could be good to be more separate if possible"
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."

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

Pros: "Comfortable flight good crew"
Cons: "The boarding process could use help, to chaotic at times but some of the has to do with the countries policies. But I’d give it a B+"

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

On time - really well operated flight. Friendly staff. Super impressed with United on this round trip.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you
