I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

We missed our flight and got stranded in Miami where we had to rent a hotel we could not afford. they would not work with us because they said it was weather related even though the gate attendant said it was not. I could go on but trying to get satisfaction has wore me down, which I believe is the intent. My only solution is to never fly AA again.

Overall it was a good flight. Because we traveled on a Saturday we were upgraded to FC since my wife and I are both Executive Platinum. The only areas for improvement we noted are better snack assortment and perhaps a little nicer plane as American is flying some older planes now. Everything else on this flight was excellent, which is frankly not the norm for American since we have had multiple issues on prior AA flights.

Didn't get a seat assignment until the last minute even though i picked a seat.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

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.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

Bags took over and hour to come out. Delays due to wind caused rebooking.

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

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.
