The WiFi on the plane was out. I also thought movie options were lacking.

The WiFi on the plane was out. I also thought movie options were lacking.

They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.

The staff and crew were wonderful. The delays were atrocious. The missed connections problematic. Getting home at 4am and having to go to work at 8 am, not a great situation. The gate agent in Huntsville was amazing. She helped everyone efficiently and with excellent problem solving skills. Her communication was helpful, timely, and thoughtful.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Great quik boarding, friendly gate agent and crew. Let early

Breakfast before landing was a reheated breakfast “calzone” which was not good, at all. Otherwise, food was good. Crew not very attentive for taking trash from passengers being a little slow in eating.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Excellent. I had a medical emergency on flight SNA-ORD and the attendants were very helpful.

The united employees at the gate treated me very rudely and called me nefarious

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

The crew was good, the WiFi was amazing, but the plane was meh. Uncomfortable first class, not enough room for baggage. My stuff ended up being behind my seat, so I had to sit on the plane for 20 minutes before I could get to it after landing.

food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

From the boarding crew to the FAs was such a good team. All with smiles and positive energy. The pilots made an announcement of us waiting on some passengers who were late landing and I didn’t hear one person feel like it was an inconvenience which was wonderful. Massive kudos to all that worked that flight. Everyone was united. 😊💙

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.
