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.

You guys broke my bag so not good, and that was the cherry on top after a 4 hour delay, change of gates, etc.

I have to sit in the middle for more than five hours because the first flight was delayed. Terrible experience. No more American Airlines.

Absolutely infuriating. I was flying standby to get home earlier after flying 4 times with American in 6 days. I was #2 on the list with seats near the front and middle, in addition to the 4 first class upgrade seats that came back into the pool. I am a Platinum member, have their card, and they put me in the 2nd to last row in the middle. No loyalty whatsoever and they lost a fan for life. There is reason people have negative comments about American and I am done supporting them.

Didn’t happe- would have missed connection so we rebooked

The airplane I love and I love I came back safe thank you American airlines

Ninth consecutive American flight I have been on that was delayed

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
