Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

Good flight, regional jet so old and seats could use an upgrade

Couldn't make the flight because connecting flight was canceled.

gate crew was courteous and helpful, flight attendant was nice and friendly once we got going. But we pushed off from the gate relatively on time, then sat there like 10 ft away, for an hour, with no announcement or explanation. Taxiing then took forever, and I get that there was runway congestion, but would be helpful to keep us posted on whats going on

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

Terrible. The flight I booked had a convenient departure time. Quick layover. And an arrival timed that worked for the people who had to pick me up. Thanks to delays and rebooking I got none of those things

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

We were upgraded to First Class and it was a great flight

We loved the steward on the plane. He made the night enjoyable
