Flight was on time. Boarding was smooth and orderly. Flight attendants were friendly and professional. Bags came out soon after arrival.

Luggage handling and communication is extremely poor. I landed in india 15th and recived luggage today. Based on my itag the luggage was in Germany. They kept me in dark. Etihad num er in india was non operatuonal. Had to call USA etihad. It should not be so difficullt. I came for 1 week business trip everything was screwed . This is the first and also will be last for me

Due to weather AA chose the poor option of redirecting my next flight to Gol airlines after 23 hours of wait. Their desk is not open during the day. Seats don’t really recline so falling asleep is a horrible challenge. Only one meal for an overnight flight. Poor experience, cheap partnership.

It was ok because it’s a short flight. The attendants weren’t friendly and didn’t serve any beverages even through they announced that they would. Also. The attendants looked messy, not presentable

APU on the aircraft was not working. No AC while boarding. Plane was extremely hot and uncomfortable. Ground AC failed. Miserable experience. Arrival at DFW, no gate available. Not sure why that keeps happening at DFW.

Everything is poor, 1st of all American Air should fix the flight schedule, I never reach my destination ever on time,

There was a 6 hours delay in our departure. And yet, no compensation was offered. A company should be responsible for such a delay.

My flight was delayed several hours, which is to be expected (American never fails to disappoint me!), but the parts that really bothered me are as follows: 1) I was unable to add myself to the standby list for another flight in the app, nor could the gate agents figure out how to help me do so (the app is difficult to work with and simply did not allow me to perform the action of adding myself to the list) 2) When I asked the gate agents to add me to the standby list, the agent said that he had added me, but I was not able to confirm that I was on the list in the app; as it turns out, I had NOT been added to the list after all. He had lied to me and/or failed to add me to the list. 3) I figured out I had not been added to the standby list when I spoke to the (rather rude, snippy, and dismissive) other gate agent, who finally did add me to the list after giving me some pretty unnecessary attitude. I understand that gate agents experience the worst of stressed travelers every day, so I appreciate that I was eventually able to make it onto the standby flight with their help. However, the app needs some SERIOUS attention!

I have never been assaulted they way I was today in Charlotte - shame on American

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.
