Seats were the worst i ever experienced — narrow, hard, no leg room and a long flight

As per usual for my flights with American Airlines, One flight was very delayed and caused me to miss my connection and they moved my flight to another day. I called customer support and was moved back to my original day but different flights. My layover flight was delayed by an additional 30 minutes while the flight crew confirmed that the plane was airworthy. Ultimately, it is less hassle to drive 10 hours than to fly 6 hours with American Airlines. I recommend my friends and family to hitch hike over taking this terrible transit.

Delayed and WIFI was not working for most of flight.

To many flight at the same hour...no respect to handicap....

We were delayed in CLT for 4 hours for mechanical issues resulting in us not leaving till 1:30AM and landing at 2:30 AM, so getting home at 4AM. The crew at the desk had no answers and provided very little information. I received a food voucher via email/app however there were no food places open. Even the walk up and scan your own places did not accept the QR code. I know mechanical issues occur but better communication would have made an unfortunate situation less frustrating.

There was no service on the flight even though there was no turbulence or any other issues on the flight. Nobody greeted at the entry or leaving the airplane, staff crew looked annoyed and not helpful at all.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

Delay of 30 minutes, but most of time recovered in flight. Lots of overhead storage, so roller bags could be kept on board and not checked.

Loved the leg room but hate I had to pay to get it!!

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.

All the above categories was great. Seats entirely too cramped.

I like American Airlines and their safety record. They provide quality service and a feel safe enough to prefer American Airlines over other carriers even if I have to pay a little more.

We paid for Business Class seats, but system did not have us and they were not available.

Worth every penny to upgrade to BC. Treated and felt more like First Class

I don't know about the others but the flight attendant that took care of us had the absolute wrong approach "how do we dare asking for water or anything else for that matter"

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines
