The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

I didn't like anything about this flight. The only reason anyone drinks Jack is because you ran out of Woodford. You should know to stock more Woodford. When you wait of first class hand and foot from the minute they get on the plane 5 feet from me but then start service from the rear of the plane so main cabin plus gets the scraps, that's how you get people to stop flying your airline.

American Airlines was horrible! The layover flight to DFW was delayed with no clear communication and for us having to stay the whole day which led to staying a night in Dallas was comped with 2 $12 dollar vouchers and a crappy hotel. We missed a whole day in Tokyo for our honeymoon and stressed the whole 24 hours. We were supposed to leave at the same time the following day, but that was delayed hours again. And instead of letting the delayed flight go first, they let the flight that was scheduled ahead of us. American should refund us the day wasted in Dallas that should have been in Tokyo! We had lost out on paid events that we can’t get refunded. When we finally did leave, it was a good flight. You would think that was the only issue with American but we from the LAX layover, we were delayed 6 hours and were given a $12 dollar voucher that covered a drink only. The only communication we were given then was that because they were delayed in a prior flight we were delayed again. I don’t understand why it was only with American that we had such a bad time with! They have definitely left a sour taste in our mouths for our honeymoon! And then they did send an email saying we could have 2K miles…. For what? To be delayed into another day and miss our flight again?

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.

In flight connectivity (via T-Mobile) was often not working.

Terrible. Internet/kiosk glitch prevented baggage checkin. Line at ticket co in Ter was under serviced and did not move. Agents did not call for flight but rather allowed time to pass. Then told each person as they reached the front if line that it was too late to check bags so they’d have to rebook flights. At least 15 people missed the flight as a result of this incompetence.

It was exactly what I expected, actually arriving sooner than scheduled.

Terrible, they canceled my flight due to an issue they had, couldn't fly me into the same place within 24 hrs so had to fly in 2.5 hrs away from my destination and spend even more money. The customer service was terrible (except at the airport in Charleston). Had to call to get my checked baggage fees reimbursed 2 wks later in which one customer service agent was very rude, wouldn't listen and then hung up on me. The second lady I spoke with was actually able to help me with that part thankfully. Would not recommend flying AA.

Delayed, missed connecting flight, ground crew double charged for international charges, were super rude and told me to just”deal with it” when I complained. Horrible airline, very frustrating.
