A little more friendliness from that crew of the day.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

My flight was delayed so bad i missed u it so i just said never mind

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

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

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.

Worst service- attendants dont want to help and sat us in front of bathroom

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

the flight is delayed, which is not uncommon but the communication was still getting hopes on reaching on time which didn't happen. When I boarded the flight it was so like unimaginably filthy. My seat belt had some sticky stuff to it like food or something from before and the space below the arm rest is accumulated dust and waste like from few months i have the pictures. Cheery on top, the airhostess was an old lady who was so bossy and mad for no reason and bossing around everyone!! worst experience ever!!

Flight was good, little delayed because of busy plane traffic

Flight was delayed multiple times and rerouted to different concourses in the airport because of all of American's delays. App/boarding pass would not update with changed gate information.

Did not know that they didn’t have screens for entertainment. I didn’t have headphones so I couldn’t watch anything on my phone.

Disorganized boarding. Mandatory to gate check bags. Curt flight staff. No space for cabin bag, even when I was in first class.

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.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Human interaction. Thought there would be more service-even a smile would have been nice.
