Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

Good flight. Connector flight was delayed so made a short turnaround in Atlanta which was stressful. Otherwise, great crew, Staff in ATL was very informative about the delay and ensured people their connections were fine. Notified the ones that were not. Great communication.

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

Delta made it easy, comfortable and timely. The crew was fantastic.

Zero updates from the pilots for 30 minutes in the tarmac

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

We were told our second flight was canceled, but it was not. We did not receive our bags for two days. I did not have my meds, so I was very sick for the first three days. Our house rental was $5700 for the week. Do the math. It will be difficult for us to fly Delta again.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Crew was not helpful. Other passengers in first class were over served blatantly over intoxicated.

Crew was wonderful, very professional and pleasant. On time performance. Excellent flights,smooth. Thank you!

Flight was delayed 14 hours due to DC air show and weather. Missed connection to MUC.

The entertainment options on the seat back video boards were nice.

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Very bad! They kept delaying my flight and wouldn’t do anything about it

IAD with the archaic people movers is just a place to be avoided.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

The flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

Check in and boarding were very easy. Quite good food and a complimentary glass of wine with dinner. The acoustics on the TV difficult at times, and the options extensive though not very updated.

Flight was not comfortable and crew was rude and not wanted to help, i would never choose united if there is alternate options . not cooperative with baby

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

My flight was delayed. We left at midnight. I got to Greensboro (GSO) at 1am. All of AA's flights in/out of Charlotte always seem to be delayed or canceled. It took me all day on Sunday to get to my destination of Cincinnati from Greensboro. I had to be rerouted through Chicago because my original flight was canceled as the door to plane was closing in GSO. The saddest part is I could have driven and arrived sooner. . . I recognize there is a lot going on that impacts travel. This week it was weather. Yesterday in Cincinnati it was President Trump. But as a frequent flyer, the flight from South Bend to Charlotte always runs late. The subsequent flight to Greensboro is always midnight to 2am. . . I do want to give props the Charlotte boarding crew. They had four flights going out of the same area at the same time. They turned it quickly and mitigated the grumbling from the crowd.

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

Flight was delayed. Not much information on when the flight would take off. Eventually we were told it was maintenance. App was not giving updates.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Flight was late and TSA had shut down so (almost) no passengers could get to the gate. American failed to inform TSA to stay open! Needed to get back home so we had to rent a car & drive 13 hours all through the night. It was bad.

For the money that I paid it was a good deal. I sat in the back of the plane and didn't pick a seat and my wife I sat together. Mission accomplished.

First off, I never complained so it is not the crews fault. The lady to my left did not respect my seat whatsoever. She was too big to lower the armrest and basically sat on me the entire flight. She was against the window. I was in a middle seat. For future reference, American, please make sure the armrest will lower or get someone a larger seat/2 seats.

We sat on the runway for over an hour bc there was a technical glitch on the ground related to baggage. Very annoying and a lot of folks missed their connection.
