We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We had a terrible experience. The flight was delayed several hours, so we missed our connection. We were told to wait at the airport. At around 11:00 pm, the flight was cancelled. There were no available seats out of Jackson for the next two days. Fortunately, we had the foresight to rebook on United for the next day. However, we had to spend a long day at the airport and an overnight at a mediocre hotel. It was a miserable way to spend part of our vacation. We also sacrificed our $450 deposit on our California hotel because we could not get there.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Flight from Fort Wayne to Atlanta was the smallest in terms of cabin space that I've ever seen. A carry on I've used for 20 years BARELY fit in overhead compartment. I'm 5'10" and felt very cramped. Not the best experience.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

The airplanes were so old and out-dated it was terrifying to fly on them.

It wasn't really their fault it was the horrible winds and we just got unlucky.

Delta flight overall it was goodT!the crew could do more and the food could be better.

Short flight. Perfect crew. Older plane. But clean and comfortable

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

I have flown Qantas multiple times in the past it seemed this flight the plane had less seat room or the seats were way less comfortable than before. Everything else was about the same. Thanks

I disliked the fact that they forced people to put up their seats during meal service

Headphone jacks worked poorly, seat recline was broken. Planes were rundown.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Great checkin experience and flight crew were very friendly and helpful

Flight was great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.

Passenger was too loud for the entire flight crew not once ask them to tame it …. Many passengers are uncomfortable including having headaches

The Mario was so helpful and provided amazing customer service however l have being waiting for a callback for almost a week now and have not heard anything further after l informed them l wanted to change my date of traveling because of my hospital appointment even send them proof and l was unable to use manag your booking on their website is a bit frustrating and l would appreciate an update on My request as soon as possible. And have called them times without numbers no response

There is no room, no gluten free options, or any free internet/entertainment. You have to bring your own tablet or smartphone because there are no screens.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Delayed 6 times. Eventually rebooked and missed a whole day of my vacation. Hot mess

Unfriendly gate staff and significant delay once we were on the plane.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

Did not get to Ontario yet. Sitting on tarmac for 2 plus hours.
