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.

Boarding was confusing from staff telling going to preboard and than to group 1 Airplane was not cooling at the beginning

Copa staff at PTY and one particular crew member were unhelpful & rude.

A lot things happened in this trip.The fly should be less stress.

Horrible. No TV or any type of entertainment on board. Passwnger listening to/watching stuff on their own phone with no headphones making it noise and uncomfortable for everyone else, little/tiny food portions, old seats, useless wifi (cant access anything). Horrible exlerience especially it was a lomg distance flight with kids.

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 Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

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

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

This airline always trick us so we end up paying again for the luggage’s. This airline is worthless and take advantage of travelers .

Now days most airlines flying to Central America have a really poor service, but if you buy first class they will treat you better. I miss those days when flying was fun.

Friendly staff at all very easy check in and organize process

Horrible airline, upgraded to sit on seats made of stone. Staff were rude and on top of it they charge an arm and a leg for luggage 🧳 never again

The seats are the worst I upgraded to premium big mistake and it seems like no one likes there job very unpleasant

they don’t have TV Seat to Type in space

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The employees at the gate were not communicating, they preferred to give the upgrade to pilots and not to the elite passengers Every flight I more disappointing, clients shooed be priority instead of other employees even if they are pilots, there was plenty room for pilots in economy

This was my first time flying with you guys and my very last! This was the most horrible experience!!! There was not even tv in the plane! How cheap can this airline be!!! I paid so much for my suitcase!!! I would never fly with this airline again! The crew are very rude!

The crew was great! They waited for me as Air Canada flight was delayed by 1:15 hours from Ottawa to Toronto. I am a bit disappointed that we could only use wifi for entertainment but I survived! The only thing I would of liked is a more comfortable seat. The seat cushions are not thick enough for flights longer than 3 hours. Aside from that, everything was great.

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

I had bad experiences before now was excellent I am glad they have business class again

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral

I upgraded to businesses class. Because of that the flight was comfortable.

I actually upgraded to the medium level of seats from basic and even doing that it may have been physically the most uncomfortable flight I have ever had. They packed everyone like is a train to death camp. It was a red eye so I hoped to get some sleep but it was physically impossible to find a comfortable way to rest. I met other folks on the same flight and they said the same thing. It was an utterly miserable flight and if I have any other options I will never fly with them again

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!
