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 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 staff at JFK were rude and unhelpful. I was harassed for the same bag that I used on my flight to jfk with no issues claiming it was the inappropriate size. The women then allowed my travel companion to board with the same size bag because they thought she was more “humble”. Also on the flight when informing the flight attendant that nationals no longer have to fill out the Bahamas immigration form my statement was met with eye rolling and attitude.

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.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

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.

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.
