Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Seat back monitors and outlets were dead and not working.

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

The flight was delayed but we got to our final destination.

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

The seats had plenty of leg room and the staff were very nice.

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.

Left my bags in origin city on a business class ticket , spent about 2-3 days in the same clothes plus the flight .

the planes are not modern there are no phone chargers

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Pros: "The crew was very interested on help and attentive with the passengers. But the seat wasn't comfortable. The design of the cushion is not the best to be seating"
Pros: "You were on time, that is the most important thing in a fly"
Cons: "You could improve your entertainment, you are not a cheap company"
Pros: "That there was seltzer"
Cons: "The management of preparing the flight and plane so that it was ready for the trip!!"

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

The flight was excellent. The crew was welcoming and attentive.

Run out of snack choices. Why are the seats not padded for your butt? Are we sitting on blocks of wood or metal for $250-300 a pop? This ain’t spirit. Let’s get it together people

Going through JFK’s security is a mess. The TSA security said no shoes on the bins. So, we place our shoes in the belt and they came out all over the belt. Boarding was delayed and Flight as well.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

The entertainment wasn’t playing in the app or online.

Lady was a bit rude during boarding and I was being nice to her.

Why does it have to be painful to fly long distances?

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Food is very bad and entertint not too many options ... flight attendet service is not good

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

The preferred seats where awful. Impossible to use them again

Delayed multiple times. Boarding was ok but getting off the aircraft was a mess. So disorganized with staff trying to help the elderly but completely blocking path for anyone else to move. Bathroom was disgusting, probably caused by one of the customers but staff couldn't care less to help clean it. No one wanted to use it since the floor was completely soaked so everyone just lined up the other restroom while the staff just chit chat with each other while looking at us.

I was in business class. There was an excellent headset. But half an hour before arrival they collected them! The rest of the trip I had to use a cheap earphone. There must be a better way to protect the headphones.

WiFi connected but only let you go to the AA website, not even text messaging worked.

I think the seats on some of their planes are uncomfortable. You can be ok on a short flight of two hours but no more than that. The delays, and also the refreshments on the plane were not enough.

Awful customer service on the phone. No phone number on the website to call a real person. Website says changes are no charge but this is a lie. I had a cheaper ticket through Kayak therefore Finnair wouldn’t change it unless I would pay the entire fare again. I begged but their agents at the airport were rude and the online chat person cut off the call with no help. Super disappointed. Wont fly this airline again and will tell everyone I meet how bad it is. Crew on the flight was nice but otherwise huge disappointment.

The flight was excellent, provided that we had inclement weather. We departed earlier than scheduled and arrived early. There was a little turbulence, but nothing to be worried about.

It was less than what is expected for a business class ticket I thought that the staff actively ignored me because I either looked Indian or Hispanic to them and I guess I did not deserve their attention. The food which included a beef entree was not available so not enough food was ordered for number of seats available. I will say experience in Greenwich lounge was very good and the staff there at the airport were very nice. May be your crew needs to learn about racial equity so that everyone gets either the same aweful treatment or hopefully the best treatment which is what we expect I recommend you take a flight with Singapore airlines that I have taken and the crew remember your last names and use it to address each person, food never finishes if you are at the back of business class and crew anticipate your need even before you articulate. Same price and 100 times better service than American Airlines

pleased with overall experienced, but seats in coach are tight.

Don't often sit in 1st class. Our experience was great.
