Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight left on time. Boarding was easy. Arrived to EWR 30 mins early. Luggage was deplaned in good time. Overall a very good experience.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

Excellent all round, first time flying United. App is very helpful.
