Never ontime and always delays. Long waits for customer service and often app doesn’t work

Arriving plane went to wrong gate. Flight Attendant was late. Was in no Hurry when he arrived. Flight was fine. Plane had to wait 20 minutes to get assigned a gate due to designated gate tied up. barely connected.. Boarded extremely late on final leg of trip.

We arrived 25 minutes early only to be told our gate was occupied and so we sat for close to 30 minutes to pull into a gate. That’s not an early arrival!

Experience was great. The best part is the free Wi-Fi connection which helps me to work on the flight

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

The TSA check in took 1.5 hours to get through in Austin and I missed my flights back to DC

As previously stated the delay I experienced flying from Wichita to Chicago caused a host of issues. When I finally was able to be booked on the last remaining American flight from Chicago to Cincinnati, the gate changed four times with the last change occurring very near the scheduled boarding time. While I didn't have a problem moving from gate to gate, I did notice and make note of others that had mobility issues and had to move each time for the gate change.

Overall, my last three trips on American Airlines have all been either delayed or "rescheduled" due to mechanical issues. At least on delay caused me to miss two possible connecting flights each later than the first. My last option for my last connection required the assistance of the onsite service desk (O'Hare Airport). The wait time for the service desk was such that it jeopardized getting booked on the last connecting flight available for the night. Suffice it to say, my latest experiences with American Airlines have caused me extensive loss of productive business and personal time and can therefore be classified as significantly less than satisfactory.

There was free WiFi (definitely a plus), but the flight was delayed 45 minutes waiting on a catering truck that never arrived. The pilot said there would be food vouchers given out at the end of the gangway to make up for the inconvenience, but there was no one offering those. Delay made me late for work!

Waiting for gate in RDU for more than 20mins is crazy.
