Cons: "Late 2 hours"

Pros: "Seats were comfortable didn’t have to pay extra for my personal day crew was polite"

Cons: "Nothing really. Very satisfied customer here."

Cons: "30 min late"

Cons: "Boarding process including changing terminals, going thru security is awful. This time I had ample of time to go Thru that long waiting process but last time I almost missed the flight.

Cons: "The flight was delayed an hour because the flight crew was late."

Cons: "On the red eye from Anchorage to LAX in Business class the A321 was ok as far as comfort. Same duration flight fromLAX to MIA, same plane, but we received a nice pillow and blanket, as well as a little travel kit and bottle of water. Seems strange there are different standards for the same duration"

Pros: "Made it to my destination"
Cons: "2-hour delay in the plan after departure from the gate for maintenance. The seats are so small that my knees hit the seat in front of me the entire flight."

Pros: "Upgraded to premium economy, nice seat, overall comfort."
Cons: "Leg rests for our seats didn’t work. Crew said ther was no fix for problem and left it at that. A bit disappointing. Fruit plate was disappointing, but pastry and yogurt was nice. Fruit wasn’t fresh."

Pros: "great trip and crew"

Pros: "great trip and crew"

Cons: "horrible food and poor service and attitude of cabin crew"

Cons: "The security check line was about a mile long at the Terminal 1, but that's not the airline's fault."

Pros: "Arrived on time, pleasant staff, but crowded. I arrived in plenty of time to make it to the gate for my connecting flight with no problem."
Cons: "There did seem to have been a problem with the entertainment video not working properly on my side of the plane. Food was more of a snack, which consisted of biscuits or pretzels and a drink."

Pros: "Nothing"
Cons: "spending $600 on a one way flight with you today has been the worst experience and rip off ever! Delayed in Hartford 6 hours. Changed my layover flight in Dallas. Now Dallas delayed 1 hour."

Pros: "Worst experience. Crew members did not show up on time which pushed everything 2 hours behind and lost connecting flight. Crew said there was customer service available but no one at airport to help. Will never fly AA again"

Pros: "Nothing"
Cons: "Our honeymoon started off with American airlines delaying us by 3 hours in Miami causing us to miss our flight to Iceland and now we are stuck in Dallas paying out of pocket for everything because American does not reimburse anything. Just brutal."

Cons: "Flight was delayed"

Cons: "Gate agent told me it wasn't his job to quickly verify if my luggage had made it on the plane after my 10 minute sprint in PHX. I know at my job, I don't get the luxury of telling customers "it's not my job", especially when the customer has had a bad experience with us."

Pros: "Enough leg room. Free movies"
Cons: "Nothing really"

Pros: "The staff was very helpful"
Cons: "I did not like the fact that, I was ask to help a non English person, whom spoke French find their way to the departure area from check in. I could not understand their broken English. That I feel is the job of the person or staff trying to check them in."

Pros: "Flight was as expected, Nothing to report."
Cons: "Seat was fine and of course when the person in from recliner it was no longer fun. And that was on premium economy."

Cons: "Flight delayed by 35 minutes"

Pros: "Excellent. on Time. Friendly crew"

Pros: "Planes were punctual and smooth flight"

Cons: "don’t know! didn’t get to phoenix because of plane issues"

Cons: "The flight was a bit delayed and was not cleaned at all, may be because of short of time, but minimized the further delay, so acceptable."

Pros: "Best part left on time and arrived early. Many thanks. Good seat room in the older S80."
Cons: "Overhead bins very full. No entertainment but that's ok for flights under 4 hours."

Cons: "Pre-booked Special meals were not catered to. Could have appreciated more friendly crew."

Pros: "Personell at Bagage drop was nice"
Cons: "First the time between connection flights was very short. Then after just making the. Innextion sat for almost 2 hours on board . Missed introductory lunch for my new summer job at my college -"

Cons: "Essentially a bus ride with the comfort of a wooden bench."

Pros: "I cannot comment because the total journey was without food."
Cons: "The crew is so rude that I was asked to remove the meat and eat the remaining. Is there no value for Veg eaters in American Airlines."

Pros: "Prompt boarding"
Cons: "I could never sync in the entertainment app and wifi"

Pros: "Pretty average flight and experience overall. Food was as expected. Average flight attendants - no one really stood out, which is odd for an international flight."
Cons: "Premium economy seat didn't decline making this the most uncomfortable and unpremium experience I've had. Sore neck and back. Searching for media such as artist or movie worthless - yields no results, yet the album is included in the listings - I stumbled on it earlier in the flight and wanted to listen to it again. Same search experience on a flight three months ago."

Pros: "Nothing"
Cons: "we had to wait for the 4th flight attendant for almost 3h in la. The Crew at the gate wasn't even able to make proper announcements. The plane didn't provide charging stations for your devices, I would expect for a flight like this that you either have screens on each seat or you're be able to charge your devices"

Pros: "Used system wide upgrade to 1st class. Excellent service"
Cons: "bumpy ride"

Cons: "They run out of food in Business Class. Service was the same as in coach."

Cons: "Ground crew was inadequate and unorganized. Ground crew caused a late flight to be even later. Plane was overbooked and the ground crew was more interested in filling the flight than accommodating Advantage Member seating."

Pros: "Seat was comfortable"
Cons: "Gate agent told me my bag would fit under seat but when I got on board found it would not and had to do gate check."

Pros: "On time."
Cons: "My aisle had a couple of vets who were just doing the job. Missed several rows during a beverage service. Not bad but nothing special."

Pros: "The flight attendant lady from 1st class/Business held my suit jacket for me to grab on the way out. Simple thing, but very thoughtful and kind. Love it."
Cons: "The negatives are puny compared to what made me happy in this trip. Thanks AA! Please thank that nice lady for me!"

Pros: "The smooth flight."

Pros: "Got home safely (eventually)"
Cons: "Left 3.5 hours late. Promised a connection the following morning and a hotel. Arrived at SFO only to be told that they would not pay for the hotel (or make arrangements) as the delay was weather related (since when is trying to leave BEFORE a typhoon hits and being LATE a weather related issue). They gave me the option of after a 13 hour flight at 11:30pm walking over to find AA staff in another terminal to argue for payment. I was too tired. After 1 million miles on AA I will avoid them now."

Cons: "I ask many AA customer assistance this question no body help me understand. I buy a seat and a 70$ extra for a premium what does this seat offer , what am I paying 70 $ for"

Pros: "Almost 20 hours before regular flight time, received numerous texts from airline that flight will be delayed. Some were delays if 4,5 hours then changed to almost 8 hrs then back to 6 hours . Needless to say connection flight is messed up and no way of knowing what that might be until arriving at airport. Then more confusion, too almost an hour to get checked in. With connecting flight of 1.5 hours which is scary for international flight that requires going through custom then recheck luggage and TSA line again. The saving grace is captain speed up place on first leg of international flight so arrived airport 1 hour early, thus allowing enough time to connect."

Cons: "Not social distanced full flight"

Pros: "New plane"

Cons: "Updated plane with new seat providing better leg room. Good inflight entertainment"

Pros: "Business class amenities"
Cons: "Luggage drop off taking over 45 minutes (for Business Class) was not acceptable."

Cons: "The flight was delayed, the first most important part is to depart on time keeping in mind the customers schedule as well that are travelling with the airline. No communication between the airline and ground department, was not happy at all and probably not fly unites again. Also they charge bags?"

Cons: "Delayed by 15mins"

Pros: "This is one of the longest flights in the world, but the flight attendants were cheerful throughout the flight. There was a good selection of movies and other entertainment in the seat back viewer."
Cons: "The food was mediocre. Lots of carbs, little protein, almost no fruits or vegetables. Not great for someone watching their weight."

Cons: "Poor food selection,"

Pros: "Arrived a little early!"
Cons: "7/8 size Brazilian airplane."

Cons: "Power at the seat was not working; bags took almost an hour to arrive at EWR"

Pros: "Not much."
Cons: "Most of crew had no concern for anyone. One of the worst flights on United in several years."

Pros: "Nothing, absolutely nothing."
Cons: "The flight attendants were pretty much what I've come to expect on U.S. airlines--overweight, older, and sloppy in appearance. One of them looked like she had rolled out of bed ten minutes before arriving at the gate. It was the complete antithesis to the flight attendants on Hong Kong Airlines. Ah, for the good old days of air travel. Before the plane ever took off it was announced the the entertainment system on the seat back ahead of those in comfort seats was not working and wouldn't be for the duration of the flight. Having paid an additional $239 for the comfort seat in the hopes of making a 16-hour flight go by a bit faster, this was unconscionable. The food was far inferior to Hong Kong Airlines. In short, it was the trip from hell."

Pros: "Same as above. Nothing to add"

Cons: "Late to board. Slow to run through safety. Late late late"

Pros: "Not much to like on United. The boarding was the best part as the staff were somewhat helpful."
Cons: "One nice flight attendant out of the five I interacted with. I'm flying United less and less because the service just sucks."

Cons: "We had a 15 hours flight and a one small meal 2 hours into the flight and a light snack sandwich after 10 hours."

Pros: "Empty flight so was able to relax."
Cons: "Foor has taken a dive. It was never so bad on United, but lately its been terrible. Got the same food, thrice, on the same flight without any change."

Pros: "The food choices were good and the service was excellent, Always kind and responsive to my needs and attentive."
Cons: "Boarding could be done by letting people with window seats being seated first, then the middle seats next and finally aisle seats last! That way people would not have to get up from their seats after they have been sitting down to get back up to allow the people in the inner seat to get to their seats a pond boarding the plane after the people in the aisle seat are already sitting!"

Pros: "Everything ran on time and the staff was very friendly."

Cons: "San Francisco to Ontario Delay for 10 min Then another dealy for 30 min After we board we had to waite inside the air craft for Cataring company to delever food for first classe"

Cons: "stewardess hardly asked what we need and feels like supplies are so limited when u ask for water its half and etc"

Pros: "no delays"

Pros: "How smooth and fast everything was"

Cons: "Narrower 777 seats noticiable when eating."

Pros: "Flight was a bit bumpy but staff was helpful and not deterred from providing great service."

Pros: "Great, friendly service Smooth flight"

Cons: "Nowhere to plug in phones or iPads. Snacks were marginal"

Pros: "Plane wasn't full"
Cons: "Coffee grounds in the bottom of my cup Seats way too small for a normal person much less for Someone with extra."

Cons: "Bag was sent LAX. I have very important documents and items in my bag. Still waiting on it to arrive..."

Pros: "N/A"
Cons: "Kept me keep waiting for aircraft for 4 hours and toward the end told me that the flight got cancelled. Then they scheduled me to the 10:45pm flight, and the aircraft didn't come in till 12:40am. I've been waiting at the airport for more than 13 hours"

Cons: "Crew n comfort"

Cons: "It was a very small plane."

Pros: "Food and service we're excellent! New plane, very comfortable seating and easy to use entertainment system"

Cons: "Plane got super delayed last minute without notice until arriving there at the gate."

Cons: "United delayed the flight over for 2 hours with over 24 hours of flight time. The reason was one of the crew memeber called in sick. When we showed the flight, we were told the flight has to make another stop in San Francisco thus delaying the flight for amther 3 hours. If they know hat they are missing a crew member over 24 hours and cannot find a replacement, this is a serious problem with United. They must be running a very tight ship."

Cons: "Totally antiquated 747 aircraft which belongs to the museum. Still showed movies on the screens instead of individual monitors at the seat. No wifi and United app did not work. Terrible entertainment."

Pros: "Good crew"

Cons: "always delay!!"

Pros: "crew members."
