The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

attendents were rude and the boarding was disjointed and poor

The trip to Harrisburg from Detroit was extremely uncomfortable because of heat

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

We sat at the gate for over 30 minutes, with no indication as to why

All was fine. Small plane so no food or entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

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

No wheel chair as requested at Atlanta arrival on first flight.

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

We left nearly 3 hours late...so that was not a good experience. We boarded and then ended up about 1 hour stuck at the gate. Not a good experience.

It is completely insane to me that first class does not include WiFi. Also does not include lounge access. Port for phone charging did not work. The crew was absolutely lovely, and the food was excellent.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

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.

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 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.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

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.

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

I wish the indicator on the side of each row was easier to decipher regarding which seat was the window, middle and row seat. Otherwise, no complains.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

First of all the check in was terrible . No customer service treated us like we are lucky to fly on American . And kayak never notified us of flight changes , I think we got a text at 3 in the morning before our flight . Charges for seats and luggage ! Really flying is just plain stressful .
