Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Internet didn’t work for this leg either. The seat was fine but didn’t have seatback screen, which I knew when I booked it. The biggest letdown is Deltas new policy on beverage/snack service not being served for flights less than 350 miles. I know this is a cost cutting measure, but how much does it really cost to give a drink and a snack for inflated airfare? I really am surprised that with Delta Comfort they don’t provide beverage/snack service given these seats cost extra to purchase. Really need to reconsider this, even if it’s for the Delta Comfort and above.

The team was wonderful. The entertainment screens were not working, so they recommended that we use the plane wifi to watch entertainment on our phones and none of the Delta entertainment links worked. Extremely frustrating process.

The plane was not clean. Vomit was removed from seat-back pocket right in front of me. The flight attendants were rude to one another. 3 children were seated together with their parents across the aisle. The children fought physically with one slamming another’s head into the plane wall at one point. The parents were aware, but took no action to intervene. Delays occurred in Atlanta after boarding before takeoff, in the air, and in Detroit after landing (no ground crew assigned). Flight attendants offered no support for connecting flights. There were weather conditions on each end of the flight, but I didn’t mark down my ratings for these.

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

I had a terrible experience. My flight got delayed from Atlanta to Chicago on Monday April 6, 2026, and that led to me missing my next flight to Brussels. United Airlines didn’t provide me with any accommodation for shelter. I had to sleep at the airport in Chicago. The next flight I was put on didn’t leave until the evening hours of Tuesday 4/7/2026.

Just a bad day to fly. Flight was delayed from scheduled 6:50 pm departure to 8:50 pm. Combination of factors mostly related to weather at the destination airport (which is where the incoming flight originated) which delayed the inbound flight over an hour. Once on board, we taxied but had to hold again on the taxiway for 10 minutes or so. We did not get wheels up until after 9 pm. The flight was smooth but about 18 minutes from our destination, we had to hold for several minutes more due to weather at ORD. We finally landed at ORD about 11:08 pm (accounting for the time difference, that was about a 3 hour delay from our scheduled departure time). It felt like we were never going to get to our destination. But the flight crew and attendants were very good. The movie selection onboard was also very nice. Got to watch half of a movie just during our taxi from the gate at ATL due to the delay!

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

The passenger in the row in front of me was listening to a political speech on his phone at full volume with no headphones and it was disturbing all of the passengers around him for several rows. I asked 2 of the flight attendants to speak to this passenger but they only shrugged. It was obvious that they were afraid there might be conflict and would not say anything. I had to take it upon myself to tell the passenger that he needed to turn it off or wear headphones as it was disturbing everyone around him not wearing their own headphones. I was very disappointed in the United flight attendants.

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

I liked that handicap assistance was right inside the door. I was able to get help right away. It is stressful when I have to think of flying and know that an airport is a large place and there is always a great distance to get to the loading area. My walking is not great anymore. With so many people flying, it is so great to have someone to assist you. I am very grateful for the help.
