Delayed because of waiting for some passengers who were delayed from their original time, they never made it to our flight. Late arrival causing logistic issues. Terrible all cause by waiting for someone who was not on time when waiting only benefits the airline

The entire process could’ve been better. Delayed multiple times and American lied and said it was due to Weather in New York, even though other flights were taking off the entire time (including other American Airlines flights)

I had 1 hour to connect flights. Boarded the first plane with a broken restroom and captain decided that the 1.25 hour flight couldn’t leave until fixed. Needless to say, I missed my connecting flight and will arrive at my final destination 6 hours late.

Flight was delayed…once landed at ORD, no gates were available so made us wait for 56 minutes after we landed to let us out of the aircraft!

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

On Wednesday, July 30 we were in mid flight from Manchester to Charlotte and we turned around because the right engine was malfunctioning. That was the last flight out of Manchester that night. I was rebooked for Thursday, which became a weather event Friday. There were no seats left on the flight from Manchester to Charlotte. Consequently I didn’t leave Manchester until Saturday morning and we flew to Chicago so to say the least my scheduled flight and return to Iowa was three days off and it messed with my business schedule. Consequently cash flow. I would like some sort of acknowledgment of this event.

We had to turn around and head back to Manchester. Problem with a plane engine.

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Seats are weirdly bent, I felt hunched the entire time.
