Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

Too short a flight to have service offered. A free simple snack offer (eg, biscuits), as in the old times, would have been nice.

Almost 2 hour delay in boarding with all standing ready to board at original time. No explanation given.

Patrons with larger bags were asked to check the bags when boarding. Seems like the most effective, and least costly way, way to successfully use the cramped space.

They cancelled our flight two times after rebooking us for a later flight. We never got on the plane. We found another solution by driving.

Mostly great. Only issue was with the WiFi. Halfway through the flight it was spotty and I was unable to work as I planned. This impacted my work products as I am traveling for business and it was an unexpected hindrance which was inconvenient. Flight here was amazing. For a 5 hour flight something more than a Biscoff would be nice but I’m just swinging at windmills I guess…

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

Delays with no explanation. It could have been handled better.

Everything was great. Boarding, early departure, early arrival, and deplaning were smooth. Smooth flight.

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Typical flight to Peoria. Had to deplane in Dallas due to lack of AC and other technical problems.
