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

The food is terrible I ask for water never got transport my mother we’re late and my sister from Lima was the worst waiting to long for wheelchair

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 Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.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

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.

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

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

Staff are the rudest in the industry … awful customer service … will never fly Avianca again

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!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport
