Pros: "I saved a passengers life"

Cons: "No personal entertainment devices on 737-800."

Cons: "Completely ignored for beverage service"

Cons: "Poor communication Delays -3 hrs"

Cons: "American Airlines was late! There was no indication that the flight was late until it was time to board, then they indicated it would be 25 minutes late, which actually turned into 50 minutes until the plane arrived. It had to be cleaned and prepared for our flight, which then took off over 1 1/2 hours late. Many passengers missed their connecting flights and American Airlines was no help... they directed people to the Miami Airport Crew. American Airlines stated that the plane was late due to air traffic control issues, but in reality the plane hadn't even arrived yet. I felt like I was lied to! Shame on American Airlines! I will never fly with this company by choice!"

Pros: "They were able to arrange for a seat for my daughter who was technically a lap child. The crew were courteous and helpful. The flight arrived early."
Cons: "Nothing."

Pros: "Relatively smooth flight"
Cons: "Seats are built for very small people. My knees were pressed into some hard surfaces for the entire 3+ hour flight. Made it a little painful to walk when we landed. The movie screens (not headrest systems) were all up overhead so you get a neck cramp watching anything. The headrest behind me pressed my shoulders forward and the extendable part would not stay up. The window stopped at about my shoulder so to look out I had to crouch down. AA better stop squeezing us for profits and start delivering a quality service or we'll all find some other airline that puts passengers first."

Pros: "On time"
Cons: "Food horrible especially for first class and entertainment did not work"

Cons: "Unexpected layover in maine. Worst and oldest planes I have ever flown in. Absolutely no entertainment options or Internet from Amsterdam to san francisco!"

Cons: "Flight was delayed, missed my connection and was told I would have to spend the night in Philly."

Cons: "The plane was a very old 767. No tv The food was ok."

Cons: "The captain announced that the flight crew exceeded 9 work hour per day due to the takeoff delay so the passengers were forced to sit and wait in a stuffy stationary aircraft for 2 hours prior to takeoff until a different crew could arrive to service the flight."

Pros: "Much better than the trip to chicago"

Pros: "Again, this flight was on time departing and early arriving. It was nice to be home a few minutes early. Thanks for that."
Cons: "Nothing you can do about this one. I don't like the little planes, so that's on me."

Cons: "delay , i am of the opinion that american airline will be late every time . it took two days to go to kingston jamaica from miami intl on 8-4-16 this should be 1. 30 hrs. that was verry poor and return on 8-28-16 flight was delay , i could understand this but two days is a bit too long . ,this happen to me so i not happy . frankie arboine"

Pros: "Nothing at all."
Cons: "Sat for 45 minutes on the runway in 100- degree heat. Death."

Pros: "Everyone and everything was awesome"
Cons: "With the ongoing situation at hand. Everything was great."

Pros: "The seats were fine and the plane was in good shape."
Cons: "The food is mediocre - everything has meat in it and they use tons of plastic. Also, the plane was late getting to the gate. This wouldn’t have been an issue had the pilot not decided to off board and then re onboard cargo (the commercial stuff they get paid to carry). This took about 20 minutes and then after the winds changed, he decided he could load more passengers. So despite having the doors locked and getting ready to leave the gate, they opened the doors up again and boarded more people for the next 40 minutes. So they chose to make a delayed flight even more delayed (on Christmas Eve). So we inevitably missed our connection in sydney and had to pay a change fee since it’s a different airline. Thanks for the Christmas gift United - you always know how to disappoint your passengers."

Cons: "WiFi was not working"

Cons: "Told I would need to check my bag at the gate, only to find plenty of overhead bin space once all passengers boarded"

Cons: "The remote in the arm rest is the worst part of the aircraft. You can never rest your arm because you will always hit the remote changing the channel or turning the screen on."

Pros: "This plane is 4 seats across ... no middle seats"
Cons: "Overhead bins are tight even for standard suitcases."

Pros: "The boarding was quick and my seat was roomy and comfortable."
Cons: "The flight was delayed due to a ground stop. That was not the annoying part. At Ronald Reagan airport we were at gate 12, flight changed to gate 16 and then changed back to gate 12. A bit confusing."

Pros: "Delayed by 2 hours"

Pros: "I got super lucky and had three seats to myself, it's a long flight just over 12hrs and good sleep is precious. The entertainment options were excellent and I watched some great first run movies. Food was quite good with options, beverage service standard. Restrooms were readily accessible and "clean.""
Cons: "We left SFO an hour late waiting for a handful of late passengers - good for them though, eh? The rest of the passengers on plane were packed in like sardines. Seemed to me that too much space on plane dedicated to the premium 'cabins' for the uber rich, but they were interesting to look at."

Cons: "We were asked to be at the airport 8hrs ahead of time, so we arrived 3am. United desk workers arrived at 4am."

Pros: "I like that I was added to the upgrade list. I used to loathe flying with United because the staff and crew were simply terrible. They were rude, unhelpful and could care less about what you needed. However, since that unfortunate incident of dragging that poor man off the plane a while back, you all have been trying very hard to get your butts in gear and do better and I see it. Keep improving the training is employees and I’ll be proud to fly with you all again."
Cons: "However the list is so long and not realistic that anyone will ever actually get upgraded. Im usually number 40 or higher and there are often maybe 4-6 actual upgrade seats. Guess it’s just a way to let everyone one where they stand so I gets it snktball awful."

Pros: "Lots of entertainment options for kids."
Cons: "Older plane, ageing bathrooms etc. Chairs not too comforatable and legroom limited. Staff ok, not particularly helpful or child-friendly. No headsets for kids. Adult earbuds do not work in little ears!"

Pros: "Safe trip. On time. Or at least reasonably so"

Pros: "All the flights were on time and the pilots terrific. They came on with information and advise. I especially liked the pilot on the travel from Hartford to Denver. he was humorous but very polite and congenial."

Pros: "Most of my flights this time had more legroom than I’ve been seeing lately. Very pleasant flight and nice not to be so cramped. The flight also left from the same terminal in Denver as my previous flight. With a 1 hour connection that was wonderful. Keep that up, United! The crew also came by regularly with offers of water. Much appreciated."
Cons: "Naturally no food except pretzels."

Cons: "No entertainment options"

Pros: "quick overall flight"
Cons: "No food options other than purchased snacks on an 8-9 hour flight"

Pros: "Crew were helpful. They got the plane boarded early for an early takeoff. It was easy getting from landing gate to my next takeoff gate."
Cons: "The boarding was a little quicker and more controlled."

Pros: "The crew from the ticket agents all the way up were great. The app for iPhone is great."
Cons: "I paid for 30 minutes of WiFi to download the United app on my iPad. I wanted to watch the movies/tv shows that were available to passengers. The WiFi was spotty and slow so I wasn’t able to load the app. Needless to say I was disappointed. I also was disappointed with the seating. I am an average size person and I felt very cramped in my seat. My shoulders and neck are killing me after a 2 hour flight. I know that I chose the economy seating but I don’t remember the seats being quite so narrow or the leg room being non existent."

Cons: "Continuously moving departure time back."

Pros: "Flights to be on time"

Cons: "Not a fan of the snack"

Pros: "Flight was on time. The united employees were really nice."
Cons: "I recently had knee surgery. So, I booked isle seats for my trip. However, I was placed in window seat on regional jets. It was pretty uncomfortable."

Pros: "The flight was on time. And it landed on time!"
Cons: "I received a " see agent" instead of a seat. When I asked about it at the gate, the woman said , I'll call you up" .?? Well no one called me up and when there were less than 10 people to board, I went up again. This time the gentleman handed me my new boarding pass. This was not cool!!!"

Pros: "Fun crew"

Cons: "They (united airlines) put my wife's luggage in the wrong flight and we are still waiting for it to arrive. It's already been 8 hrs since we landed and every time we call them, they're telling us it's scanned in a different city. Now she is without clothes and her necessities."

Pros: "I didn't like anything"
Cons: "They say I miss check in by 1min. There was no more flights to NY. I told them to connect me to Bradley in Connecticut, they say no they can only get me flights on. My original destination. In which they don't have any. They send me all the way to Newark. So i had to find my way to NY then to CT. The TSA officers that work at this airline are awful. Overall experience was horrible. I would give it zero stars if I can."

Pros: "Seat had room"
Cons: "Could not lay back"

Cons: "It was a very small plane."

Pros: "Too many delays to be able to take the flight."

Pros: "Hot, 3hrs delayed. /should have notified us about the delay sooner so we didn't waste the day"
Cons: "Very hot plane"

Cons: "No food. Horrible service"

Cons: "Lines, delays, at least the agent I called while in line was helpful."

Pros: "was finally able to get the upgrade"

Pros: "Flight arrived about 20 min early. Crew kept us updated on turbulence. Crew followed up for additional drinks/refills."
Cons: "Audio jack not working, so couldn't enjoy in-flight entertainment."

Pros: "No issues or delays"
Cons: "Nothing"

Pros: "Nothing"
Cons: "Almost everything"

Pros: "I have absolutely nothing to say good about this airport"
Cons: "We were canceled (our flight in Newark) were herded around like cattle and then left to fend for ourselves .. With no apologies .. We got jumbled around to three different flights until we found one that would fit they try to get us on one flight and boarded in like 45 minutes and there was no way were going to make it manageable us around again , it was awful.."

Pros: "Early"

Pros: "United transfer me to Alaska Airlines because there was delay that would impacted my layover.. So they gave me non stop with Alaska. I'm pleased with their service!"
Cons: "Nothing"

Pros: "Flight crew very friendly"
Cons: "Flight delay"

Pros: "Good flight attendants."
Cons: "Nothing"

Pros: "Flight cancelled"
Cons: "Flight cancelled. Had to wait 30 minutes to speak to United service rep to rebook to Boston. No other Manchester flights. Forced to check carry ons. There were 10 terminals for service reps and only five reps. Line was very long and reps were in no hurry to assist. Not a pleasant experience. They should pay us a cancellation fee like they charge us when we cancel. Incurred additional expense getting to Manchester, NH. Not happy with United."

Pros: "The flight attendants were great, and the in cabin experience went smoothly."
Cons: "It took over half an hour, for the plane to depart from the runway. In addition, the gate was changed three times without overhead announcements from O'Hare."

Pros: "Easily the best flight of our entire trip. Airplanes was nicer so the others couldn't help that but the crew was outstanding on this flight. All of them were amazing! Kindness is what the world needs and all three were wonderful. The comfort was also the best on this plane. This was the first time flying with United."
Cons: "Problem was after the flight. My luggage was lost. This was the first trip with United so I'm not sure about the future. This was the first time my luggage has ever been misplaced."

Pros: "I wish all airlines were like Lufthansa. Lufthansa still cares about the passengers, while others only care about profit."

Cons: "The fact that the tv is on constantly without the option to turn it off is annoying. The viewing length to passenger is too short to really enjoy (Probably not your fault). PLEASE permit us to turn it off. The constant repeating of the Dish commercials while in dead air space is so annoying I will never consider Dish as a provider.! Please play more than one entertaining video than repeating the one about alligators (crocodiles?)."

Pros: "Flight was on time."
Cons: "Plane was freezing cold. Even with numerous empty seats I was assigned a seat in the last row next to the laboratory and not permitted to change. Flight attendant had a poor attitude and was generally not helpful."

Cons: "Great"

Pros: "On time and friendly"
