Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Boarded early, left early, arrived 40 mins early! A win win for me!

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

We had a delay, but thankfully I made it to my connection. Overall it went smooth

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Flight delayed 45 minutes almost caused us to miss connection to transatlantic flight.

Vegetarian food options were pretty tasteless. Gob of rice with absolutely no protein, barely any vegetables, and poorly seasoned. Food was the major disappointment of an otherwise good flight experience. However, food is a differentiator on long haul flights.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Caring & friendly crew. Most important: got us SAFELY to our destination!

Friendly flight attendants, decent food if you can eat dairy.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

Flight was delayed due to connecting passengers. Lack of snack options bad. Sitting in Aisle, last cart run pulled the cart directly into my knee. Rude awakening.

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

Another uncoordinated American experience. Always surprises me at DFW for them of all places. Have to take this flight as there are no other good time options. We knew from the start that something was wrong, but the pilot wouldn't tell us. I just watched my Kayak app grow the delay by 10 minutes as it went to 3.5 hours. They were uncoordinated with maintenance (as maintenance, when finally arriving, knew within 15 minutes the plane wasn't going. No 'sorry' or 'this is what is going on' comment. The pilot seemed unfazed / didn't care about the process we were going through.

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

The flight back to Dallas was delayed, which has happened to me several times with American Airlines. There was no announcement, no update sent out, no compensation offered for the inconvenience.

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.

Waiting area not big enough for all the passengers, no airport lounge.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture
