Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

It's fine but Newark to Nashville was too long

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.

Passenger was too loud for the entire flight crew not once ask them to tame it …. Many passengers are uncomfortable including having headaches

Flight canceled because they didn’t have enough flight attendants. No refunds or credits for future flights

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

Nothing, I wont be flying American Airlines again and will not be recommending anyone to fly American Airlines. It was the worst experience flying I've ever had.

Boarding was awful - no order, people cutting in line, completely chaotic Planes are very old and uncomfortable. Noticeable difference between Delta and United on same route.

Getting to Scotland with no luggage (no medicine, no clothes and no club) on golf trip very disappointed

I think since I am an AA Advantage member, my checked bags should have been free, but I paid for all 4 of us.

A little late at the start but all worked out well.

The flight from DFW to chs was delayed with multiple gate changes.

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.
