We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

It is usually very pleasant. Good service for the price, international flights are even better

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

The flight attendant in first class was beyond rude and didn't care at all about her job. AND the gate agent was even worse than the flight attendant for rudeness. She was awful.

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Quick flight. No time to stress over it. Over before it begins.

Very good, boarded and took off on time and landed early

Delayed boarding because a flight attendant couldn't find the gate...sat on the plane for over an hour at the gate because AA couldn't get one of the planes behind us to move

It was awful. My first flight was delayed and as a consequence I lost my second flight to Greensboro. I did not know what to do so I rebook myself a flight to Charlotte . It was very inconvenient I not to have anybody form corporate assisting me either from PwC or from kayak . It is a very disappointing experience that American did not wait 1 minute or told me to rebook before making the first flight

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

Horrible experience, delays after delays. A flight that should arrive 11:50pm just landed past 1 am, and another 30min waiting for the baggage to come out. Very disappointing.

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.
