Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

The seats from lax to DFW was so tight that I could not move my legs . No WiFi and had to pay . Not a good selection of entertainment

The flight was good. We had to spend almost an hour on the tarmac when we arrived in Dallas. Waiting for a gate. What’s the point of arriving early if you have no gate to park at?

Lower WiFi prices; allow us to see our flight on a map; more variety of drink choices.

Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?
