Cons: "Arriving on time to make connection although I am not sure 1 hour 30 minutes was long enough to make our next flight. The baggage took a very long time."

Cons: "I ordered kosher food and again American Airlines didn’t get me any"

Pros: "Crew was friendly and nice."

Cons: "Time"

Cons: "Seat space"

Pros: "The seats are hard and unconfortable for a long trip"

Cons: "Delayed three hours with no communication or compensation. Poor customer service"

Cons: "Better communication about handicap persons. I called twice and notified two people about my mom and her wheelchair but no one tells the gate to put a ramp up to the regional jet on the tarmac. Three ring circus as usual ."

Pros: "Arrived early. Friendly pilot."
Cons: "Attendant did not offer snack choice."

Pros: "Service was good"
Cons: "Nothing"

Pros: "The crew"
Cons: "The food"

Pros: "Nice leg room in exit row"
Cons: "My travel companion and I encountered the most unfriendly and non respondent flight crew of all time."

Cons: "6 hour mechanical delay"

Pros: "Good smooth flight and quick"
Cons: "I left my iPad in the seat pocket and they said they didn’t find it!"

Cons: "I’m not sure how this flight was as I missed it due to a delay from YYZ to ORD"

Pros: "My connecting flight from london arrived late and the crew made sure i made it onto the flight to stl even though I barely made it to the gate on time."

Pros: "Clean, Friendly flight attendant"
Cons: "I don’t understand how a brief meaning less than 30 minutes thunderstorm can cause a five hour delay. Every time I take the route from DCA to STL American is always really late"

Pros: "crew was pleasant"

Pros: "My flight was fine - I paid for a Premium Seat, which also allowed me a premium boarding position, which I highly recommend for anyone flying. The seat was comfortable, the staff was very friendly and I really liked the in-flight entertainment."
Cons: "At the DFW security post for my gate, there was NO TSA-pre. That service stops at 7pm. I would think at a major airport like DFW where American Airlines has a hub, they would make sure to staff that longer. Just getting to keep my shoes on, while having to drag all my electronics and liquids out, take my coat and belt off, etc. is not acceptable. AA should put the pressure on DFW to treat their customers better!"

Pros: "The dinner was good"
Cons: "All the flight attendants were hanging out in the back. Socializing like we were invisible. They seemed to prioritize one another over the passengers. It felt a little odd."

Pros: "Flight was pleasant and all the crew members were courteous."

Cons: "Flight was delayed almost two hours due to crew staffing issues."

Pros: "Flight crew very friendly."
Cons: "Everything was as expected. 1 star on entertainment as there was none. Would have liked to have been able to get 3 seats together without extra charges."

Cons: "It was nice. And boarding was good too."

Pros: "This flight is the normal nonstop from Mia to StL. The seating is tight but not completely uncomfortable."
Cons: "I just had knee replacement 4 1/2 months ago. It was difficult to fully extend my leg under the seat in front of me because the space between rows has shrunk to include more seating."

Cons: "the fly got delayed for more than 3 hours."

Cons: "There was just an announcement that the refreshments will be served shortly but there were no refreshments. Take off and landing was horrible. Flight was shaking way more than usual."

Pros: "It was easy to travel"

Pros: "Good food"
Cons: "Online check in for one of our two passengers was impossible. Simply never worked. At airport check in desk, manual data entry errors during airport check in caused issues during customs at the end of the flight. Also we were not seated together initially even tho reservations were made months in advance. Airline online check in was pushing us to pay extra for seats together."

Pros: "Easy and customer service at lax was awesome and very helpful!!!"
Cons: "The 45 minute bag time that's it may or may not be able to go 45 mins within boarding ."

Pros: "This was the same crew and pilot from the flight I took to LAX. His landing was so smooth, I woke up pleasantly upon landing!"

Pros: "Great staff."
Cons: "The hour delay due to maintenance and fueling."

Pros: "Why would a jet this size wobble all the way across the Atlantic! The pretzels were even stale, and they served a "pizza" that was a stale mini loaf with sauce and a little mozzarella. People were starving when breakfast was served. The thermostat fluctuated from horribly hot to freeing - for 14 hrs. The crew slammed things down on table trays, grumped, were giving harsh orders to patrons rather than gently directing them. These ladies do not enjoy their job. I am done with Delta. We were also an hour late taking off due to a door on a cargo hold not closing. I was embarrassed that our Aussie friends experienced this as their first American flight."
Cons: "Food, attitude of flight attendants, comfort of cabin. Pilot took charge of thermostat issue and kept us informed in a friendly manner regarding the status of our take off and flight progress."

Pros: "On time"
Cons: "Boarding numbers"

Pros: "My neighbor."
Cons: "We sat on the tarmac for over an hour for no apparent reason."

Cons: "I nearly missed my flight because I did not have a seat for a flight that I bought a ticket for at full price. Which, would lead one to believe that I would have a seat on said flight. However, coming to the gate an hour before boarding the personnel working gate the said he was having computer difficulties and could not get me a seat and it would be 10 min. I continued to return till boarding to find out I had no seat and I was on standby. Upon going to customer service they replied the airline oversold tickets and every airline does this as if to make this practice ok. Well being in sales myself and if I were to sell x amount of product to one customer ( or several) I better make sure I have it all there to deliver. People rely on you schedule wise. It nearly shot a meeting I had to make in the foot. Very disappointed with the airline and the way things were handled."

Pros: "Speedy boarding"
Cons: "Unmotivated crew, uncomfortable seats."

Cons: "American Airlines delayed my flight over 16 hours. Very unhappy."

Cons: "Boarding was chaotic, with people sitting in wrong seats and walking the wrong way down the plane. Crew were not especially friendly. I know it was at the tail end of a long Sunday, but it wasn't impressive."

Pros: "Entertainment, 110 plugins for devices, internet."
Cons: "only free meal option was cinnamon cookies."

Pros: "The ginger ale."
Cons: "This was my return trip with more delays due to maintenance issues of the aircraft. 10/17/16 flight 1585 was the outgoing flight delayed five hours on my departing trip. I waited at the baggage carousel 15 minutes for my bag after over an hour delay due to switching aircrafts. With a flight arriving this late in the evening with the low volume of bags checked (due to checked luggage charges), this should not be the case. Five minutes to gulp down ginger ale."

Pros: "All flights were on time Greatly enjoyed the trip"

Pros: "On time, arrived early."
Cons: "Seats too close in front of you."

Pros: "Flight was on time. Plane was clean. Staff very professional."

Cons: "Attempted to make my connection which was in another terminal. Could not get onboard as they shut the doors. My rerouted flight was in a different terminal. Overall a very disappointing travel experience."

Pros: "It took off on time and life was good."

Pros: "The plane has improved greatly with their comfort and leg space"
Cons: "With checking my luggage my bag fee was waived a total of seven times this trip because I'm a military wife to see my husband overseas who is serving a year in Saudi Arabi except this past time on October 2nd at DCA airport. Spoke with the Supervisor Ralph who stated it was against policy. How stringent is this policy if it was waived seven times previously? Policy needs to be reviewed with entire staff. I will no longer use American Airlines because their military convenience and policies no longer seem to favor the military. My husband also after speaking with him will also no longer use your airline including all his members he overseas when they return after their year tour."

Pros: "The people"
Cons: "The seats are too small I'm 6'1 and that's not that tall"

Pros: "Right in time and crew very responsable."
Cons: "The audio for film's didn't function in many places of the plain."

"Awful and terrible flight attendants with very poor skills and service and no empathy for the passengers"

Pros: "On time/early."
Cons: "Menu items in Polaris."

Pros: "Smooth flight"

Pros: "Good"
Cons: "Good"

Pros: "The flight departed early and arrived early, good flight attendant service"
Cons: "Long wait on the cold jetbridge for our carryon baggage, tight quarters on the plane"

Pros: "I had absolutely no complaints about this trip"

Cons: "Electrical service was spotty"

Cons: "Custom agents were rude."

Cons: "Luggage took >1hr. Flew w Copa - always got bad seats when on United flights"

Pros: "Flight attendant was friendly and plane ride was smooth."
Cons: "Flight got delayed twice (3+hours total) then we had to wait another 40 minutes for the plane to get there, deplane, and get cleaned up and restocked."

Cons: "flight was over two hours late because of a late incoming plane. That may be for good reason, but we weren't told until less than one hour before takeoff. It doesn't make sense that the airline just found out one hour before takeoff that the flight was two hours behind. We should have been told sooner about the delay, while we had other choices of alternate flights."

Pros: "In flight staff was fantastic"
Cons: "Boarding was awful. I didn't have a seat when I checked in, then was told I could take American flight with a partial credit. Then they gave me a seat last minute. I didn't approx ya r"

Pros: "That the flight was earlier then Expected"
Cons: "Bag fee"

Pros: "Flight was ok"
Cons: "It was late"

Pros: "Nothing to like when an agent tells you that 8 seats open on plane .but already full!"
Cons: "See above!"

Cons: "Flight was 3 1/2 hours delayed. Missed my original connection. Missed the second connection because (as the attendants told us) they were unable to get ANY flight information to inform the passengers of where their connecting flight was. They were also pretty snotty and acted like it was our fault that we might miss a flight. I'm now sitting in Houston for the final flight of the day."

Pros: "Ease of checking in by phone & printing out board passes."
Cons: "That the ride was so rough. Pilot apologized & said it was just a bad nite. It was a smaller plane so that maybe made the turbulence feel worse too."

Pros: "We got my wife on a plane home in under four hours."
Cons: "United decided to bump some of their glorified bus drivers ahead of me on standby so I had to wait a full four hours in O'Hare listening to some doichebag from LA try to entertain folks at the Goose Island bar with his stories about selling franchises."

Pros: "The snacks were great"
Cons: "Clearly a new flight crew. They needed some more practice with efficiency and reading the statements they are required to make. Previous flight was over an hour late arriving at the airport meaning that our flight was just as late departing for our flight. First we were told the flight was 20 minutes late, then 8 minutes late, then 40 minutes late, then 55 minutes late... Every time they told us the incoming flight was about to land."

Pros: "It was fast & we didn't die we're the only good things"
Cons: "The Flight attendant was rude and mean , the plane was small and old .. But most of all he flight attendant ruined the flight for everyone. I even heard people saying she was mean as they were getting off the flight. I think her career as a flight attendant has ran its course (she was pretty old also)"

Pros: "Flight was delayed..boarding for St Louis was one of the worse flights I have ever seen..crew was rude..asked for a juice and she was mad because I didn't finish it..very uncomfortable flight..small plane."
Cons: "Got home"

Pros: "Great crew"
Cons: "No room on board for carry on luggage and when gate checking luggage it resulted in further delaying me to make my connecting flight"

Pros: "I really liked that the flight attendants came through to offer drinks and pick up trash several times and not just once, even after the turbulence that we had. I really liked the alternative wafers instead of the traditional trail mix or peanuts."
Cons: "I have no complaints with my flight, but I would sincerely appreciate if United offered some kind of neck pillow or a thin rolled up blanket for extra comfort on longer flights (5+ hours). These minor comforts are forgotten when packing my own bags when worrying about everything else."

Cons: "It's 2.5 hours past our scheduled departure time and we're still sitting at the gate"

Pros: "Still not in stl"
Cons: "Still not in stl"

Pros: "United really could have done better informing us of delay, then cancellation. I knew it was likely to be delayed due to weather, and kept checking the status. It wasn't listed as delayed until nearly boarding time, although it seems pretty clear they knew well before that. But SFO was a star. The new decor is sophisticated and comfortable. Bathrooms were like at a swanky night club! Comfy chairs and charging outlets every where. The biggest hit was the Exploratorium installation, which kept my and plenty of other kids entertained!"
Cons: "Wayfinding signage from BART is confusing. BART connection is a pain. The machines in the station only take $1 and $5 bills-- no 20s or credit cards! And no one at BART cares if you are running late for a flight."

Pros: "Food was just ok. Fly twice with delta international and was spoiled,"
Cons: "Crew no customer service, the boarding lines international & domestic were a jungle. Even boarding pass line to check in lugguage had 200 people in it and only one flight out. No fast Kioskos and many people standing around 6 to be exact not helping and just standing so people don't go into another airlines lines. Useless"

Cons: "Girl at gate was rude!!! After missing connecting because of Uniteds negligence, my brand new luggage first time used, zipper to main compartment was ripped half way out!! My clothes and stuff hanging out as its coming out baggage claim!!!!!! This was a nightmare"

Pros: "UAL customer service horrible. Would not pay for a hotel room we needed due to UAL canceling our flight. Customer service reps few & far between UAL bus at Terminal C gate 71 at 10p 9/30/2016 had rude employees refusing to acknowledge is or help rather they listened to music on their cell phones. FIRE THEM."

Cons: "The snacks are too small."

Cons: "STINGY DRINK SERVINGS TINY SNACK BAGS"

Pros: "Nothing"
Cons: "Flight got camcelled made me late to duty station"

Pros: "Staff was friendly"
Cons: "Delayed for 2 hrs after my 4 hr layover"

Cons: "Some other carriers offer wifi inflight service free of charge. I tried connecting to wifi in flight with no success several times."

Pros: "Leg room in seats better than on some airlines. Staff friendly."
Cons: "Both flights were delayed. One hour going and two hours on return."

Cons: "Our flight got canceled due to airport issues at our destination. United canceled the flight but had no alternative flights to get us home. Flights the next day were full. Took over an hour with the service desk to reroute tickets to cancel them and to get bags back then took two hours at baggage claim to get the bags back. Customer service was basically useless. After all that, we didn't get any of our money back! I will be avoiding United airlines. Flight cancelation was not their fault but the way they handled the rest of it was embarrassing."

Pros: "The young lady who was the flight attendant was very nice and tried to make a very bad situation somewhat bearable. There were a number of children on the flight that she was very attentive to. I hope united treats their employees better than they treat their passengers."
Cons: "The flight was delayed for 4 hours. We were told to proceed to the United terminal in spite of the delay. There seemed to be no effort to inform or assist us. There was very little to do in this terminal but wait to see if our flight would eventually come. There were other United passengers in the terminal who were also waiting for overly delayed flights. eventually, we had a plane that was extremely small, cramped and uncomfortable. United seems to consistently oversell its seats and then tried to get people to give up their seats. Very poorly managed airline with bad customer service. Sadly, I have to say that I have never had an acceptable experience on a united flight. Will NOT take another United flight."

Pros: "Same as above. Did notice the woman staffing the counter at boarding having extreme patience with people's problems and non problems. She was great and deserves a raise. Denver gate B 85 between 1:00 and 3:00 6/15/16."

Pros: "I liked that they waited for me because my flight was late getting in to San Francisco."

Pros: "Nothing"
Cons: "The service. The flight attendants were rude"

Pros: "No much"
Cons: "Take forever to load. No entertainment. Hard, uncomfortable seats, no food. Kept talking about "premiere plus" benefits. Why does it cost $80 to have not bad service?"

Pros: "flight was on time"
Cons: "airport gate lady would't let me run to the bathroom and quickly return for my checked carry-on for "security reasons." Then I heard about 4-5 people being paged to come pick up their checked carry-on luggage."

Cons: "lost our bag, crying babies, uncomfortable plane"

Pros: "The flight was very pleasurable. Smooth takeoff."

Pros: "I was comfortable and I didn't die."
Cons: "N/A"

Pros: "Had to wait standby but got on the flight. Was very happy about that!!"

Cons: "System was screwed up, boarding was a nightmare."

Cons: "The service was good, but I found a hard object in my chicken dinner like someone lost a molar. I couldn't finish the supper."

Pros: "Courteous crew."
Cons: "Old cramped plane (EMB 135/145). Was dingy, dirty and smelled bad, no wi-fi or entertainment options. Very loud ride even though I was near the front far from the engines."

Pros: "Nothing"
Cons: "Delayed 2 hours because they had to change tires they didn't decide that until everyone was already on the plane then had to deboard counter people were very rude this airline is always delayed for something probably the worst airline ever"
