Staff and flight attendants were very polite. Flight was smooth. My seat on the plane was a bit broken so it would not stay in upright position but it was fine for the most part.

Staff and flight attendants were very polite. Flight was smooth. My seat on the plane was a bit broken so it would not stay in upright position but it was fine for the most part.

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

My bags were misplaced!!! Im in a foreign country with no bags

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Flight is clean and ontime. Crew is friendly. Snack can be better and the internet connection is poor

United airlines, mediocre at best. No issues , nothing great . Worked for me

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Our flight from Denver to Honolulu was delayed by close to 4 hrs. The only concession that was offered was a $15 food voucher to be used at the airport. They texted the vouchers after we boarded so there was now way to use them.the food they did serve was cold. I can’t recommend this airline.

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

It’s love good long way travel!! I always want more give me price down i want ever month travel I miss travel only North Carolina to Thailand in my love her !!

Efficiency of supporting mechanical teams who changed a wheel on airplane in minutes. So no delay, and pilot made up the lost minutes in flight. Comfortable seat.

We had multiple delays and a medical incident during the flight. We barely got a glass of water during the over 4 hours we were on the plane. Somehow first class got all of their service. It would be nice if all of your paying customers got the service they paid for.

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
