Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

This flight is a quick way to get to Chicago, but a bit expensive.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

Staff friendly and app worked really well. Modest delays were frustrating

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.

I sat in seat 22D near the back right of the plane. My phone battery was getting low, so I plugged my charger into the power outlets below the seats in front of me. They did not work. When I asked the flight attendant whether this was the case for the whole plane he said, "No. It's only this one. It hasn't worked for months". This should be noted to whomever services this plane so that maintenance can fix this for future passengers. I was on Flight AA5614 from Grand Rapids to Philadelphia on Wednesday, September 23, 2026.

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

It was a good trip. Flight Attendants were friendly and responsive.

They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.

The trip was very smooth and they provided great customer service

Everything was excellent. I loved my flight Thank you so much 😊

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

I had first class itinerary, yet they put me boarding group 5! I spoke with the gate agent though, and she let me board in Group 1 like I should have been assigned. Would've liked water
