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.

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

Everything was pretty good except for food. They need to improve on it compared to other airlines.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

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.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.
