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.

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.

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

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.

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.

Gate crew helping to scan tickets was a little short tempered with customers. Flight crew was very friendly, welcoming , and provided excellent service on board.

Everything went well with the flight. But one of the flight attendants had on inappropriate pants. She had on an old worn out pair of sweat pants. The back seam was unrivaled and should not have been worn for work. If I had not seen her in the airport with the standard type of luggage, I certainly would not have thought she was working for Delta. Not a good look at all for representation.

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.

One of the crew members, a male complained about my bag being too heavy, which I felt was really unnecessary. I am disabled and would have carried it myself if I thought it was going to be a problem. In addition the landing was rough because everyone gasped in unison which it touched down.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Surly, unhelpful ground staff at JFK. There was a complete lack of empathy—a flawed check-in ordeal caused us to miss our flight. All airlines that I have ever flown would have worked to help me solve the ticket problem. Instead, frontline employees shrugged their shoulders and pointed fingers at us for having made an error. I will do anything to avoid EVER flying on Jet Blue again. It well deserves its low rank among airlines.

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Nice flight, nice crew but no cookie or napkin with my seltzer.

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

EWR terminal C United Club is great. Flight and everything else mediocre

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

Very bad , airplain had problem with engines , had to evacuate, had a delay on my trip for almost 4 hours , lost my rental car in london..

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Easy boarding in group 2. Landed 1/2 hr early. Delicious cookie snack.

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.

Generally good but we were delayed almost two hours from the original time of purchase. The pilot claimed an internal issue then an external equipment issue that needed to be adddressed. He made up a lot of the time.

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.

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours

It was great, love the experience and will definitely recommend 👌. Communication was great

The flight got canceled multiple times and we had to drive their to reach midnight for our next morning interview. Poor and unriable experience. Now have to ask for a refund since we didn't need their rescheduled flight three days later.

In flight wifi that I paid for was very slow and at times didn't work at all.

No food, not even snacks on the 6hr flight from Newark to Vancouver! The movie collection made up for it though and they did come around with drinks twice. Just good to know so you can eat ahead/bring snacks onto the flight. It was a bumpy ride induced by wind and rain but otherwise got to the destination safely and promptly.

Announcements were to loud, too insistent and too often. The same messages can be made in a nice relaxed, yet efficient manner. There is no need to "talk down" as if on a mild power trip. It's immature and unnecessary. This is a constant irritant especially with Air Canada. Learn from your European competitors to have a bit of class.

My flight was cancelled. The flight they booked me on was delayed over 2 hours with mechanical problems so I missed my connection and they ran out of hotel rooms, so I had to book and pay for it on my own. I also had to pay for food out of pocket. It was a terrible experience.

Date was for a day earlier than I realized and no email or text up on check in. At least I could have made an effort to re-arrange my schedule to use the flight. 100% write off + cost of new ticket.

The agents lied and said flight was completely full, (wasn’t even have full) then proceeded to take everyone’s roller bags even though there was plenty room to accommodate them on the flight.

The Air Canada agents in Newark are the best in the system!
