Pros: "Flight did not take place because of cancelled return flight. the whole itinerary was cancelled."
Cons: "because of cancelled flight I had to schedule a new itinerary directly through American Airlines. The cost increased from $947.50 to $1,873 plus airport parking for 17 days."

Pros: "Flight was delayed by approximately 90 minutes. Attendant was friendly."

Pros: "We got to our destination safely, and American provided us with extra legroom seats."
Cons: "Service was curt and there was only phone-based entertainment."

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "Spacious seats"

Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."

Cons: "No entertainment options"

Pros: "I was so happy I could check in online and boarding was a breeze. I actually got to sit by the window when my original seat was in the middle. So nice of the ladies to suggest it to me."
Cons: "No complaints"

Cons: "The video monitor for my seat was broken. So, low entertainment score."

Pros: "everything was on tyime"

Pros: "On time take off"

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."

Cons: "Flight was late, got a message from Kayak that it was delayed 3 hours...thank goodness I happened to check again, because then it was only delayed for 41 mins, then it gave me an update that it was only 21 mins delayed, then went back to 41! Pretty inconvenient, and it would have been nice to get a text, not just some silent pop up"

Pros: "Got to La Guardia almost 26 minutes early but then waited FORTY minutes for the gate!"
Cons: "AA needs better coordination with the horrible La Guardia airport"

Cons: "Delayed a total of four hous!"

Cons: "good"

Pros: "Flight was on time, staff was friendly and boarding was organized."
Cons: "I'm a small person (5'-2", 105lbs) and I didn't have room to breathe in that tiny little seat."

Pros: "Smooth - trouble free - calm process"

Pros: "Arrived to the airport well ahead of time and encountered lines so long that we were not able to make our flight. Only 2 attendants working and so many people had to be rebooked we didn't get another flight for 3 days. Did I mention I was traveling with a baby?"

Pros: "On time arrival"
Cons: "Everything else"

Pros: "Nothing"
Cons: "The storage are very small, by the time i boarded everything was full. I had to hand carry bags and i had to put it in front of me which is a very small space already, on top of that i had the window sit so i had no space to move. it was very uncomfortable, and flight was delayed. We sat there for an hour before taking off but i understand its due to the weather but it was my worst plane ride not worth 300dollars. I will not ride american airline again."

Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."

Cons: "Everything was great."

Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."

Pros: "The flight attendants were great and very friendly!"
Cons: "The wifi wasn't very good so I couldn't access the in flight entertainment I also had my own snacks so I didn't buy any food"

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Pros: "On time. Good leg room."
Cons: "Valet flight, i.e. even normal sized carry-on cannot be stowed above the seat We arrived at the gate 20 min before departure, due to TSA delays. But they closed the door and no one was around to even talk to. At least they put us in the next flight.... Still, as we're not checking in any bags, they could have let us in."

Cons: "Got to charlotte with 80 minutes to connect. Sat on the tarmac for 60 waiting for a gate. Missed connection by <5 minutes. Thanks, AA!"

Pros: "Non stop"
Cons: "Airline"

Cons: "Boarding took forever, the flight was over 2 hours late which caused me to miss my connecting flight and my military orders were not honored - I still had to pay extra to take all my gear back to my duty station. Never had that issue with any other American airline."

Pros: "Crew was fine even when we had to sit on the ground for 1 1/2 hours for a repair."
Cons: "American Airlines didn't honor my choice of seats."

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "I like the quite clam and smooth flight. The attendants were very helpful; and kind."
Cons: "I did not like that fact that I change me flight to the next day and had to pay $200.00 for a ticket change. I feel if there are opening we should not have to pay an additional charge of $200.00. $50 for a ticket change is understandable, but $200.00. Things do happen and changes must be made. Cynthia J. Black- Finch cynthiajfinch@gmail.com"

Pros: "The plane crew were quite kind and efficient"
Cons: "When we bought our tickets we asked about how much time to allow between the London flight and our connection to Knoxville. We booked expecting to take the early connection if we could get thru customs early enough. We did, asked for boarding passes and were told it would cost $150.00 to take the earlier flight...so we sat for more than 3 hours waiting for our connection, after buying over $2,000 in airfare, traveling for 24 hours and seeing a partly empty plane leave Charlotte for Knoxville. We were the given the back two non reclining seats on the flight, even though we had booked weeks in advance...so no we felt very let down at the end of a difficult trip."

Pros: "I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are"
Cons: "The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist"

Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"

Pros: "Plenty of leg room no entertainment so I dozed."
Cons: "People stuffing oversized bags in overhead."

Pros: "The movies"
Cons: "No Food"

Pros: "One I love free sodies and two I love free sodies with a smile. I definitely got both with this flight crew."
Cons: "Not enough sodies and I couldn't smell my own farts."

Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."

Cons: "We were delayed for 4 hours, due to a mechanical issue. We were not given any forms of reimbursement. I would like a 500.00 voucher."

Cons: "Flight was delayed."

Cons: "Would be nice to know ahead of time if flight is equipped with an in seat television so as to be prepared to bring headphones."

Pros: "We arrived safe."
Cons: "Departure 1.5 hours late. Missed connection. Travel took 16 hours instead of 6 hours."

Pros: "All great."

Pros: "Nothing"

Pros: "Everything was timely."
Cons: "No complaints"

Pros: "I was very pleased that the attendant gave me a free drink since I had a military ID. It was very kind of her."
Cons: "The flight was delayed multiple times. We were never informed as to why this was. It was very frustrating since I had a connecting flight into Tucson from Dallas. I got off the plane with twenty minutes to get to my next flight which was not in the same terminal. The plane was also incredibly hot while we waited to take off, I was beginning to become uneasy and nauseous."

Pros: "Zero of it"
Cons: "The fact they cancelled this flight for no reason, didn't contact me at all even though they had all of my information and than barely tried to re book me. They wanted me to take 3 connecting the flights the next day. And the next flight I was able to get on 24 hours later, I almost wasn't allowed to check in because they couldn't find my reservation."

Pros: "Very good service"

Pros: "Quick boarding, departed on time, arrived early, good cabin communication"
Cons: "This is a very cramped commuter jet, just one flight attendant to serve entire plane, she came by once for drinks but not a second time"

Pros: "Efficient crew. It"
Cons: "It was good overall."

Pros: "the fact that the flight arrived on time without delay and the gates were easy to locate."
Cons: "How on earth did my i arrived lagos and only one out of my two bags showed up, i have to extend my stay in lagos and hoping my bag will come the next day, i have to pay $100 extra just to extend my one night hotel booking to two nights."

Pros: "Crew was extremely friendly."
Cons: "Temperature was way too warm."

Pros: "was upgraded"
Cons: "nothing"

Pros: "Nothing"
Cons: "No meal on business, no free internet, no entertainment"

Pros: "smooth flight, good service"
Cons: "hold up to board family with 2 much luggage, overhead bins 2 small"

Pros: "The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United."
Cons: "The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft."

Pros: "Good communication and helpful."
Cons: "Delays"

Pros: "The boarding process went smoothly and was on schedule."
Cons: "Overhead compartment filled up and it was hard funding space for my bag."

Cons: "Massive delays on both flights out of O'Hare... No leg room...."

Cons: "aborted takeoff due to mechanical problem, a bit scary but crew opted for safety and we changed to another plane;thus, long delay but unavoidable."

Cons: "I went on this trip as an veterinary humanitarian out reach. I was also guardian to one high school student so that she might have an experience of such to guild her future. Her flight was missed booked to leave after mine, I attempted to rebook my flight with Luthansia but they would not let me me even partial rebook. I attempted a number of times to rebook the flight but their solution was extreme financial gain for them when more reasonable alternative could have been arranged. They canceled my entire return flight and left me stranded. I had to piece together a return flight on a shoe string budget. Thankfully American Airlines was understanding for it appears Luthansia and United are not."

Pros: "Everything was great on the flight- we even got a snack ( stroopwafel cookie reminiscent of when I lived in Amsterdam ) and a drink. I haven't flown united in a while and was pleasantly surprised."
Cons: "Nothing but my flights were short ( under 1 hours)"

Cons: "Completely missed meeting due to 6 changes made during flight - Ask for a refund of some sort and non was given - not even air-miles or ticket recognition. Customer service from United was almost non existent. Will not be flying with united ever again."

Cons: "Ok"

Pros: "Good"
Cons: "Good"

Cons: "Little more time between flights would be nice"

Cons: "Luggage compartment too small even for a rolling laptop bag"

Cons: "Flight was cancelled. I am still stranded and was given no accommodations so had to pay for a hotel in addition to costing me a full day's wages in missed work. The United staff I spoke with by phone and in person were neither helpful not pleasant. I will go out of my way to never fly United again."

Pros: "Was able to get on an earlier flight"

Pros: "The crew. Short and sweet flight."
Cons: "Small seats. Bad coffee."

Pros: "Good service"
Cons: "Delay in air"

Pros: "I like the seats and the leg space .they were very comfortable ."
Cons: "No comment"

Cons: "The delay. It was approximately a 2 hour delay getting to Arcata."

Pros: "Wifi on flight"

Pros: "All the crew were friendly and accommodating."
Cons: "Waiting so long for the flight to actually take off. Very late !"

Pros: "That the plane arrived on time, which is a miracle in itself."
Cons: "No offer by the Flight Attendant to any passenger if they wanted extra snacks or if they desired to have the entire can of soft drink they requested. Only one A/C was operational, so thank God we cruising at altitude cooled the cabin down."

Pros: "Gate agent was great.... Have me an edit row seat. But my 90 minute flight from St Louis, led to a 40 minute wait for my bag"

Pros: "New (to me) lime sparkling soda And a cookie too! Seemed to be a little more seat and leg room."
Cons: "I only wish your branded credit card did not cost$95.00 after first year."

Pros: "we were 10 minutes early to the gate"
Cons: "super cramped quarters, like touching legs to the next person the whole squirmy flight close... the plane was made for little people."

Pros: "Price was lowest for that date and itinerary."
Cons: "Feels like United is second class compared to other carriers. I purchased this for my Morher-n-Law who rarely flies was traveling by herself. there were 7 gate changes 3 day of. I Was very concerned if she would make it."

Pros: "Rain delayed our take off but most of the time was made up. No complaints!"
Cons: "Forced to check our carry on suitcase even though there was plenty of room above the seats."

Pros: "Newer plane,"

Pros: "They got me on a flight home that night"
Cons: "I had to wait 4 hours in the St. Louis airport and 4 hours in the Dallas airport. Was a very long day!!!! I do not like to fly American Airlines and that was the only flight that was available. The plains are small and cabin pressure always hurts my ears."

Cons: "Late out of Stl. Missed flight out of Chicago"

Pros: "Flight was on time"

Cons: "I wish we would have known ahead of time that we needed our own personal devises to watch a movie. We would have been better prepared. We didn't" have long to download the Intied app and for some it just wouldn't load so they could watch a movie. I also wish there was a better selection of movie to watch."

Pros: "Departed close to on-time. And as a pilot myself any landing you walk away from is a good landing."
Cons: "Boarding nearly last there was no room in the overhead compartments. This aircraft is tiny and with my small bag on the floor my feet rested on top of my bag making it cramped."

Cons: "The only complaint is to have to pay for the TV. I feel it should be part of the service. On the way going to Punta Cana the flight attendant gave it to us for free and that was very nice as it made the trip seem to go by faster. Other then that everything was wonderful."

Pros: "Once we got on board the flight attendant was very nice and accommodating. The flight itself was fine."
Cons: "We had to wait 4 hours to board our flight. The plane was late, then they had to replace the whole navigation system. Then at the last minute told us to go to another gate and when we got there we were told to go back to the original gate. Getting another plane from the get go would have eliminated a lot of the hassle we all experienced."

Pros: "On time. Quick boarding, very efficient."
Cons: "Stewardess was a little grumpy."

Cons: "Delayed over an hour in STL, which caused me to miss my connection to Hartford. United rebooked me on Delta. I had to go from STL to Newark (United) then to Detroit to Hartford (Delta). I was in airports for over 14 hours. I was 7 1/2 hours late leaving compared to my original schedule and arrived at the hotel the next day. I had 5.5 hours of sleep for an interview that I traveled for in Hartfford. Thanks United."

Cons: "Flight cancelled due to mechanical, re-booked on Delta who had to re-book me on Alaska due to mechanical. An 8 hr trip turned to 22hrs."

Pros: "When we got to Chicago we didn't have a plane so we had to wait hours and then walked to another gate .. Wait for another hour and then they said we would not have anything to drink or eat in the flight"

Pros: "The attendant at the boarding counter was very helpful."
Cons: "As we are flying international and had a single itinerary, They didn't allow two checked in baggage's inspite of repeatedly explaining them that we have to take connecting flight which allows two checked in baggage's for each person."

Pros: "The flight attendants were very awesome, fun and professional, and super friendly.... My only negative was this plane didn't offer wifi... If there is going to be an extra charge for the WiFi through United Airlines, then EVERY plane should offer it. Otherwise their should not be a charge."

Cons: "Our original flight got cancelled out of St Louis, not once did the service agent tell me I could rebook my connecting flights myself on my phone. When I found out, I successfully rebooked my partner's flight and my reservation disappeared. Because of this I was on standby (along with 87) other people while my partner had a ticket."

Pros: "Was fast and smooth"
