There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

I was pleasantly surprised with an upgrade at boarding. I finally had a mostly gluten free food options and a very attentive attendant.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Good crew and a great experience. Only good things to say.

Staff at the gate were incredibly rude, hostile and threatening. Never fly American Airlines.

I had a horrible experience from the time I dropped off my bags until the time I landed. The staff taking the bags at the check-in counter prior to security, forced me to check my baby stroller, even though it weighed less than 20 pounds. their excuse was that the wheels were too big. I have never had an issue gate checking this exact same stroller in the past either on American or on any other airline. when I asked for the agent to show me the rule about the size of the wheels on strollers, they told me to look it up on the AA website. I did so, and did not find any indication that wheel size was a problem for gate checking strollers. The only limitation would be the weight of the stroller which mine was below. I was left with a one-year-old child and all of my carry-on luggage, diaper bag, and the like to walk around the airport without the assistance of a stroller and had the same issue when I exited the plane and had to go all the way to baggage claim without a stroller. In addition, while on the airplane, I was told I can only get one bag of cookies as a snack, even though I was with a child. Apparently my child and I were supposed to share a cookie. While this latter issue is a minor one, it is just another example of the absolutely horrible customer service that American Airlines provides. In addition, the 737 aircraft that I was on was extremely hot and the air vents above the seat were so far away from the aisle and middle seats that it was comical. I could barely reach the air vent to adjust it. I had to ask the person in the window seat to do it for me. The whole experience was just a nightmare.
