Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.

did not have enough meal for first class passengers so offer us snack

Arrived 40 min early which was great - sat in runway for 35 min so no gain. Then waited for luggage 45 min. They need to staff accordingly knowing its one of the busiest week in Phx

Broke my luggage and I can't get a resolution yet.

My flight got rerouted due to crew rest. I was sent to Dallas customer service was not very polite. Was given a $40 room voucher for Motel 6 and $12 to eat with. It delayed me by a day. Where if I would have just stuck with my original flight Arizona was delayed to Cleveland and I could have made it home. They put me on a 9:00 flight out of Dallas to Cleveland without my knowledge or consent. When originally I was told it would be 8:45 a.m. on February 1st. I told them I could not take the 9:00 flight because I did not have anybody to pick me up from the airport at that time. I'm extremely disappointed in how I was treated. And I will not fly American Airlines again.

I am very appreciative of the help provided to me by Dennis and Whitney. I had lost my phone at EWR airport and they were very kind in assisting me. This included advice on how to file a report and also helping me connect with family. The pilot was also great about keeping passengers updated on the flight progress with regular communications over the system.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

Old equipment, needs upgrade and seat comfort. Internet didn't work 75% or the time.

The screens were inoperable for movies and such, but everything else was just fine

For a 5 1/2 hour flite i considered the "business class" to be subpar. The seats were just ok, no amenities, really nothing more than a long domestic flight. Frankly disappointed.
