It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Ultimately fine but plane seemed dated and creaky and landing was hard…. At no time did I feel unsafe so thank you.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

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 Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.
