Cons: "Seat space"

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

Pros: "Would’ve loved if the flight from Louisville to Charlotte weren’t delayed 2 hours for mechanical reasons!"
Cons: "The flight could’ve waited for us instead of leaving on time for Allentown!"

Cons: "Person in front of me had seat reclined from take off to landing. Nobody checked. Nobody told him it had to be upright during takeoff and landing. I believe that is a safety issue. Isn’t that why the flight attendants are there?"

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: "Crew friendly and accommodating, even on short flight"
Cons: "Good - no complaints."

Cons: "Beverages"

Cons: "6 hour mechanical delay"

Cons: "First flight delayed 45 min, then cancelled. 2nd flight 3 hrs later."

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: "Great pilot. Outstanding control over the plane. Arrived an hour and a half before originally forecasted three days prior."

Cons: "Made us wait over 2 hours on the tarmac before take off inside the airplane."

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: "The crew were friendly and did their job effectively"
Cons: "Lack of seat space Planes seemed old Minimal overhead storage room—carry on fits all other airlines overhead but struggled to get bag in compartment Also, no help from crew with this Seats recline nearly into lap of person behind"

Cons: "After being delayed without any explanation, I was told that I would not have my purchased 1st Class seat. To add to that I received no service In economy."

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

Pros: "My flight wasn't completely full, so I had a row to myself. The pilot was excellent; takeoff and landing were very smooth."
Cons: "I had to gate check my luggage because of the small plane size. Had I had a shorter layover this could have caused an issue for me."

Pros: "It was easy to travel"

Cons: "Too many delays. Having to de-board after boarding."

Cons: "Plane was not board on time. Delayed taking off."

Pros: "The middle seat was empty I had an aisle seat. That was wonderful."
Cons: "No wifi screens for books or movies but I had my iPhone."

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."

Pros: "Everything was fine except it was inexplicably late!"
Cons: "It was over 30mins late for no reason!"

Cons: "Seemed to be an unnecessary delay in departing a half hour late"

Pros: "Courteous crew, easy experience smooth "get in and get out" process"
Cons: "Flight was late due to weather but that's beyond anyone's control obviously"

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."

Cons: "Forced to check my carry on. Took 30min for the bags to come out on the carousel. Which is why i never check my bag."

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

Pros: "We boarded fast and the flight was smooth. The crew was very friendly."
Cons: "The sears were a little uncomfortable. They went terrible but my back started to go out on my 2 hour plans ride."

Pros: "very friendly staff"

Pros: "Nothing to expect from Domestic fight."

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: "Plane was ancient"

Pros: "Good"

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

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

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."

Cons: "The delay!!!"

Pros: "The trip experience was very nice. Although we left later than before we made up time in the air and was able to arrive ahead of schedule. The crew was one person but was very courteous and professional."

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

Pros: "Nothing"
Cons: "Cancelled the flight two hours before departure. Weren't apologetic."

Cons: "Had to pay for entertainment. This was my 50th flight this year and first time any airline has no free entertainment. Probably will boycott united on future flights"

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: "I overslept my flight and United was able to find the next available flight into Denver which helped me tremendously. The guy on the phone was very pleasant and helped so much."
Cons: "Boarding was disorganized and hard to understand. Flight was delayed because of paperwork that wasn't signed, which caused me to miss my connecting flight."

Pros: "There is no food essentially. No entertainment unless you have your own electronic hand-held device."
Cons: "See above."

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."

Cons: "The plane wasn't very clean. And I might have liked another option besides a weird trail mix for a snack."

Cons: "It was freezing on the plane."

Cons: "Seats are too close."

Pros: "The Embraer ERJ-170 has comfortable seats!"

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)"

Cons: "More leg room"

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: "The plane was unboarded due to mechanical problem but a new plane was found and within an hour we were back on board. Appreciate the quick turnaround."

Pros: "Nothing. It's just ok."
Cons: "Nothing, just ok."

Pros: "The seats were comfortable and spacious place were awesome :) The snack was very good, the best I had so far while flying. Service was great :)"
Cons: "I didn't like that because I was 4th group to get in the plane, all the space above my seat was full and I had to go put my carry-on quite further down. It didn't cause me any problem because my connection flight had a long layover, but if had not been, I could have been late."

Cons: "The snacks are too small."

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

Pros: "newer plane. more personal space per seat"

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 amenities are fabulous. The flight was very comfortable."

Pros: "Nothing"
Cons: "Held up at check in because of understaffing. Long TSA line. When we finally got to gate wouldn't let us board. Then agent was extremely rude about putting us on a different flight. Have always flown Delta and am sorry I ever strayed. It will never happen again."

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: "service was great"

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: "There was no air circulating on the plane the entire flight. The plane was over 90 degrees when we got on. Everyone on the flight asked for the air to be on and we were told it was. No air was coming out of the vents. Horrible flight."

Pros: "Nothing. I am stranded in an airport. Delayed nearly 14 hours. American airlines fixed the issue since united could not. Never again."
Cons: "Everything. I am stranded in an airport. My original flight was at 10:05pm. My new flight is at 11:45am. American airlines stepped up and helped me get a flight out earlier. I am now on a one stop flight instead of non stop, even though I paid for direct. Not very happy and will not use untied again."

Pros: "Nothing."
Cons: "Everything."

Cons: "Cramped space."

Pros: "Nothing"
Cons: "Flight was 3 hrs late leaving Louisville and there was no acknowledgement of that or apology from the United staff."

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"
