Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

My flight was delayed a very short period of time but they did not hold my connecting flight to San Diego, also through United. So they closed the doors before we got off our plane. They would only have to help the door open for another five to ten minutes. So I missed a court deadline for a manditory mediation settlement conference for my client. I had to get an associate to be there in person and be on the phone with him relaying what he needs to do the entire time. The court was very upset with me and so was my client. United cannot be trusted.

Multiple delays and not straight answer from the United team

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Crew professional. Easy bag drop off. On time. Good entertainment.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

The boarding crew was incredibly helpful getting me on an earlier flight

They have lost any customer service care and support. Terrible airline now and been for awhile.

The flight was delayed leaving Miami. When we arrived in Charlotte, we were unable to park at our scheduled gate. We had to wait another 30-45 minutes before we could park at a different gate. All in all, we were delayed by almost two hours arriving in Charlotte.
