Pros: "The crew did a great job. The seat was uncomfortable after such a long flight. But that is to be expected, I guess. The lady, kicking our seats behind us, because she felt it was disrespectful to recline your seat, even during a 9 hour flight, was the only drawback. But the crew responded approp"
Cons: "The best part about the food was the ice cream. The rest of the food was lackluster, but what I expected on a flight. The lady kicking our seats behind us because she thought it was disrespectful to recline made for an uncomfortable flight. The rest was as good as expected on American Airlines"

Pros: "On time departure, this flight tends to get delayed, not this time. Good service and pleasant flight."
Cons: "I prefer personal entertainment systems."

Cons: "the tremendous pressure from the staff, at the American Airlines. Never before experience such a low and virtually feel like an inmate, Just because the person in doing so, was profiling and that is NO GOOD , also the airport is filthy and dirty , Nobody Cares...I will not come again as a tourist to that country.. American Airlines should train the staff to be more courteous and not to ask that many questions ..it feels like you where in Siberia.."

Pros: "everything but the cabin temperature. it was very hot and uncomfortable."
Cons: "Too warm in the cabin."

Cons: "We booked our airline tickets at the same time and our seats were separate. This was the first time flying for my wife so she was very upset when we found out our seats were not together. We had to pay an extra $60 to have the seats moved to an exit seat."

Pros: "Can’t say anything good"
Cons: "When boarding crew was rude because carry on did not fit the overhead compartment. No options to choose from for entertainment. Flight was delayed almost an hour while sitting in plane. Food options almost nonexistent"

Pros: "Good space in premium"
Cons: "Female cabin crew were aggressive, discourteous and frankly rude to the passengers when they had to verbally communicate. I hear this so often with American cabin crew. When I started to experience this I became aware of the same trend in regard communications with other passengers. Very unattractive."

Pros: "Very nice crew. The flight attendants were very patient and efficient. Flight was very smooth and surprisingly not overcrowded. For the first time, in a long time, when getting off of the plane it was very organized and not everyone rushing and pushing to get off. Everyone followed suit and did row by row, and no one pushing or shoving which is always nice."
Cons: "The only this I would suggest is that on a longer flight you should offer better deals on food/snacks."

Pros: "Flight attendant was great; talkative, funny, entertaining."
Cons: "Inclement weather"

Pros: "Everything was fine except..."
Cons: "The directions don’t work to connect to in flight entertainment."

Pros: "Friendly staff"
Cons: "Food was terrible and the seats tight"

Pros: "The crew was very friendly and accommodating. The food as usual just snack type food for purchase as expected. The entertainment system malfunctioned and we could not watch the movie they offered. However one flight attendant was very nice and gave my kids special cookies. Nice touch!"

Pros: "Comfortable flight on-time Good service Great attitude from the crew and the airport personnel"
Cons: "no TV or movie screen"

Pros: "Everything about the flight was great"

Pros: "Mostly everyrhing"
Cons: "Food was so so"

Cons: "Seats were quite uncomfortable, there was no entertainment options, there was no way to charge any electronic devices because the plane was so old, which meant I almost wasn't able to catch a ride home after the flight. For a cross-country flight, I would expect a better experience."

Cons: "Cramped seating, uncomfortable cabin temperature, very hard/jolting landing"

Pros: "The duration of the flight, nothing to do with the airline"
Cons: "I was forced to check a bag in when I had flown previously the week before with the same carry on. $50 spent for nothing in my opinion. Per the supervisor over head bin size does not change yet my bag was "too big" like I said I had flown literally 4 days before this trip and had no problems with my bag fitting nor did any of the flight attendants say anything. I am just annoyed. Also I didn't know that I would fly American as it's through Alaska originally, maybe that was my lack of attention to detail. The carry on situation is what irritated me the most. This is also not the first time that I've had a problem with American Air."

Pros: "Cookie hehehh"

Pros: "the clerk at the boarding desk was kind"
Cons: "delayed"

Pros: "Boarding was quick and easy, no problems or hassles. Seat reclined and was reasonably comfortable. Left early, arrived even earlier."
Cons: "Crew was more robotic than human, which is bexoming a trend on AA. No smiles, no acknowledgment, just doing the job of handing out food and picking up trash. No personal touch whatsoever. Food was subpar for an AA flight, especially international. Entertainment system has many defects and problems, for example "search" is useless. Uninspiring and forgettable film choices as well. The knob to control air flow was broken which made it chilly. To finish as I started, a more engaged and pleasant crew could have made all the other things more palpable and acceptable. They were just too cold, like the temperature in the cabin and distant."

Cons: "Sat next to a dog guy and the crew did not help with the situation"

Pros: "Excellent crew."
Cons: "Obese people should have to declare their weight and pay for two seats."

Pros: "Cockpit crew kept us informed of arrival time adjustments and upcoming turbulence. Enjoyed choices of music. Seats were surprisingly comfortable."

Pros: "Punctual!"
Cons: "no entertainment! Nothing. On the flight from Mex City to LAX the bathroom facilities were so limited that some Economy class passengers had to try to use the business class or first class facilities' An FA then came on the intercom and said Economy class must only use their own facilities and this is according to an FAA regulation. THat is a straight out lie. If you eliminate bathrooms from Economy class to squeeze in more seats this problem will persist. American Airlines should be ashamed of itself."

Pros: "Nice entertainment on new 737."
Cons: "But it is a 3-3 and there no room to sit cause we are hip to hip which means shoulders overlap shoulders. It is horrible. Avoid this plane at all costs. It's really bad. Pitch of leg room is barely OK but side to side they have sunk to a new low. The new plane doesn't blow any air. Terrible system. Really? That should be easy to fix."

Pros: "I did not like anything about the flight to be honest. Oh wait you did have cool club lights that were blue that tried to distract me from the fact that I had to take an American airlines flight."
Cons: "Holy moly. You know if you stopped charging extra money for checked baggage you wouldn't have a ridiculously annoying amount of customers with too many bags for overhead storage. Then you wouldn't have to threaten your customers to store their small bags under the seat. Then I would have room for my feet under the seat. When I would have been comfortable. I also wouldn't have to annoy my neighbor with trying to move and get comfortable. But instead the exact opposite happened and I'm offended you guys have America anywhere near your name."

Cons: "Food"

Pros: "Inflight movies"
Cons: "None"

Pros: "The food and the crew"
Cons: "Entertainment system, it is outdated"

Pros: "Amabilidad de la tripulacion"
Cons: "Podrían dar comida, el viaje no es tan corto. Aire acondicionado demasiado frío, muchos pasajeros solicitaron regular l temperatura, no habían suficientes mantas"

Cons: "Very very delayed. Made traveling home difficult on me and my family."

Cons: "Flight was canceled due to United's mismanagement of crews."

Pros: "Clean, comfortable and on time."
Cons: "Nothing"

Cons: "No screens in the seats. Food options are the usual limited fair"

Cons: "I’m 6’3, misty in my legs, so the diminishing legroom is a problem. Can’t afford business class either. You should really have entertainment for a 5 hr flight."

Cons: "slight delay but still made connecting flight"

Pros: "Comfortable seats with screens"
Cons: "Mediocre snack"

Cons: "I didn't get to get on the flight."

Cons: "Slow boarding, no food no drinks, no tv."

Pros: "Nothinh"
Cons: "The flight crew’s non challent attitude"

Pros: "Nothing"

Pros: "Más espacio, al menos una película que ver, y algún bocadillo por ser un vuelo de tantas horas"

Pros: "The pilot"
Cons: "Everything else"

Cons: "Plane seats were so narrow that my knees were pressed into the back of seat infront of me."

Pros: "Entertainment worked on this flight! And once again, I had an empty seat next to me - that's always a huge plus so I can stretch a bit."

Pros: "The flight crew was very attentive and friendly. Probably one of the nicest crews I have encountered on my flights."
Cons: "Me and this other person were waiting in the back for the two bathrooms to become available. We waited over 10 minutes."

Pros: "The stewardesses were fabulous! Very kind and accommodating. Both candy and the other woman helped me out in getting my musical instrument onboard without it being a hassle."
Cons: "Seats could've reclined a little more."

Pros: "The plane took two hours to leave the ground due to weather. This was unfortunate and made the passengers uncomfortable but it was not the fault of the airline."
Cons: "The airline gave all the passengers access to the movies and television channels."

Cons: "My luggage didn't make connnection."

Pros: "Quick check-in proceds"
Cons: "Honestly, everything was fine."

Pros: "The ticket staff. The only thing about the Harlingen airport is that it needs more than a couple of exray machines ....the Valley is woefully behind in staff training and technology. It took forever to get through the short lines...it was too long of a wait."
Cons: "The way that a couple of young AA men who were biligirent, combative and vulgar upset about their seat assignments. I told one of the young men to stop using vulgarity and no way to treat the lady that was doing her job, she continued treating them with courtesy and they kept mumbling under their breath God knows what. So young and already so bitter. They were towering over her and took a confrontational stance...she finally called security. I would not allowed them on the plane. I commend the young lady there in Harlingen."

Pros: "So they lost my bag but where super helpful and nice!"

Pros: "First flight delayed once board to check a broken light. Then waisted 40 minutes taxiing on tarmac in Houston because they couldn't find a gate. Missed our connection. They put us up in a low end hotel overnight. Then we had our morning flight again delayed as we waited for planes to the take off, so further delays. Arrived in Costa Rica 1 hour late. Now with too many other flights so immigration packed and took another hour and twenty minutes (when we finished there was only a 5 minute wait). Thanks United"
Cons: "Coffee and cookies. Moscow mule"

Pros: "Flight crew was friendly"
Cons: "Flight delayed for over 2 hours. Missed connecting flight."

Cons: "Snack offering was caramely sugar cookie"

Pros: "Just an easy flight that day. Got Eco Premium seat and made big difference."

Pros: "Boarding was easy and fast."
Cons: "Flight attendant was Asian and couldn't understand his English. Other passengers said same thing!"

Cons: "Fligh delay."

Pros: "Everyone seemed to be caring and helpful."
Cons: "No entertainment whatsoever. They can at least put wifi."

Pros: "I was allowed to get off the aircraft to collect a bag I left behind"

Pros: "Attendants were amazing"
Cons: "We spent the whole delay on the plane and wasn't notified of a problem until after an hour. A lot of my time was wasted. That's not okay. Keep your customers informed."

Pros: "The boarding process is terrible, because communication breakdown is inevitable. The crew on the plane are sometimes rude, and have no patience when passing seated passengers. One air hostess constantly bumped into my arm like a bull as she passed walking down the isle. Entertainment is practically non-existent on long flights unless you pay for it. Two of my flights were cancelled last minute with little to no remorse, and I had to wait 2 days to catch the next flight. That flight was even delayed more than an hour. I was sick by time I reached my destination. Overall, United would not be my 1st choice due to bad experiences numerous times."

Pros: "Since we were the last ones to arrive at the gate because of our delayed flight they had to check our carry-on baggage with the luggage we didn't have locks and nomally what we carry in that bag are fragile or valuable things. They should at least have plastic gauzes or fragile stickers to put on the bags. I don't know the reason but the flight attendants left about the last 6 rows of passengers without pretzels or drinks. There was no device to view movies. Leg space too tight."

Pros: "Nice and comfy seats, good service on plane, fast boarding"
Cons: "No good food and the entertainment was not the beat"

Pros: "Just the crew"
Cons: "Now when I fly united i feel like flying with spirit or jet blue o any other cheap airline, they charge for everything but sodas. They don't even carry blankets. The fact that for a long (3h- 4h and 5h) flight (took 4 overall during the holidays) united didn't offered ONE movie for free at least was very disappointing. Not one of my flights were on-time!"

Cons: "Same. No ffood ..poor Service and allso charging. To much for extra weight. $200 for 3 extra pounds. Ridiculous. Also charged for one check in bag..Todo much"

Cons: "Viajar en United es desastroso. Los asientos son demasiado pequeños, yo mido1.57 metros y no me podía ni mover."

Pros: "It was a smooth flight."
Cons: "The airport was really inefficient. The flight itself was good, very smooth landing. No food offered as it was so early in the morning and such a short flight."

Pros: "The crew were nice though exasperated with cramped new planes and crowded restrooms. Flight was on time"
Cons: "After three years of flying all around US, realized United is the worst of the three major legacy carriers. I'm star alliance gold and it's still a painful experience. Crew admitted in latest redesign of planes they've managed to squeeze another six seats in coach. My seat wouldn't go back but even if it did, would feel too guilty for person behind to do it - so little legroom on newer planes. They've also cut down on restrooms so for most of the flight there was a line of 5-6 people waiting in the aisle. American Airlines seems to have older planes but at least decent legroom (and I'm not tall - anybody over 5'10 would have to sit at an angle on new United planes!). Been very impressed by Delta's service lately. United feels more like Spirit"

Pros: "The staff that worked for United was very friendly, professional, and they provided great alternatives due to the fact that the flight was delayed for almost 2 hours. They offered paid lodging and food vouchers if I would've missed my flight."
Cons: "The flight was delayed for almost 2 hours because there was a maintenance problem. It left me with a five minute layover to get from one gate to the different gate One building away for my connecting flight. The plane also felt very old and definitely needs to be updated or replaced. The plastic panels where the lights and air vents are were slightly damaged to the point where they would dip low from the ceiling. No entertainment was offered."

Pros: "The staff was really polite and were willig to answer all questions with a smile."
Cons: "The seat I was on could not be reclined. This was most unpleasant because it was an overnight flight. You should earn the clients - even economy passengers - when this seat is the one being assigned to them. I would payed beforehand to get a more comfortable seat if I'd known I was to fly on a no-reclining seat on an overnight flight."

Pros: "Nothing"
Cons: "They delayed the flight due to "operational difficulties". I understand this happens, however, their communication towards customers was unacceptable. They first announced a 20 min delay, followed by another 30 min, then 30 more and then 30 more than then 30 more! They basically kept us at the gate for 2 1/2 hours until the found another plane. For a business like United, and flying out of their hub this is completely unacceptable. We ended up leaving at 11pm for a flight scheduled at 8. They didnt give anything in the plane to make up for it. No food, no free wifi, nothing."

Pros: "The seat next to me was empty"
Cons: "United put my bags on the next flight to San Jose, so I had to wait an extra 2.5 hours in the airport for the next plane to land in San Jose, Costa Rica while my ride waited for me."

Cons: "The seats were so small, with no space between rows that you couldn't even recline. The tv on the seat in front was so close you couldn't watch it. Miserable flight, and I'm only 5'5"."

Pros: "Terrible"
Cons: "Everything"

Cons: "I felt like tuna in a can."
