Very turbulent flight, no drinks, very little service, unorganized boarding, gate changed multiple times

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

Significant delays on my trip to Chicago and my trip back to NY

Delayed by 5 hours and I had to wit in the airport for more than 6+ hours.

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

It wa sort of on time; the cab was left with some trash

My pillow had a shoe print on it, when I asked if I can have another pillow, I was told “I’m sorry but it is one pillow per guest, do YOU want to turn it inside out” to which I responded , no thanks I will go without. This is generally not ok, but For the price tag I paid flying business this is absolutely unacceptable. Hopefully American Airlines can update their accommodations to bedding that is not tossed on the ground and stepped on, or at least have a couple of extra pillows in hand, incase someone had decided to step on the pillows for what ever reason

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

Even though we left CMI late, we mostly made up the time.
