Pros: "Leg room"
Cons: "The onboard crew was rude and one guy actually grabbed me which to me is unprofessional. All because I had a poster tube that wasn't in my bag they wanted it in my bag. Then I asked for a seat change due to my size hard for ne to be in the middle and the lady was snooty about it."

Cons: "I bought WiFi for my iPhone on the flight and could barely use it because it kept kicking me off and was super slow."

Cons: "I think boarding from rear would facilitate faster boarding And eliminate people blocking Aisle ( standing in aisle and digging In their carryons preventing people From finding their seats further down the aisle. Also people with a connecting flight Pressed for time on their next flight Departure...Should be allowed to deplane first..so they don't miss their next flight."

Pros: "Nothing"
Cons: "Foot room. Baggage room. Entertainment. Service"

Pros: "Flight attendants were amazing. Definitely some of the best I've ever encountered."
Cons: "Crew at the desk were rude. They also enacted policies that I'd never seen before about gate checking, and implied I was crazy when I noted how unusual it was. I literally came off a previous AA flight with the previous policy and they said I was confusing them with AE."

Cons: "As always, the crew was friendly, professional and accommodating."

Pros: "Fast boarding and unloading."
Cons: "Flight leaving on time."

Pros: "The snacks."
Cons: "This was the worst flight I've ever been on. Delayed 7 hours. Made it to deicing pad only to be told we needed to turn back to the gate due to technical issues. Kept being told 15 more minutes until departure."

Pros: "Th flight was a few minutes late boarding but we landed on time. It was a nice smooth flight!"

Pros: "The staff were polite and the pilot kept us on time. The flight wasn’t over booked and I was able to have an extra seat between myself and the other passenger in my row."
Cons: "That due to the Kayak purchase I had to wait until the last group to board."

Pros: "It was on time. I liked the head rests on the seats."

Pros: "Nothing"
Cons: "Many things Food Services Entertainment"

Cons: "There was a lot of announcements on the very early flight trying to get people to signup for a credit card...too early for all those unimportant announcements :("

Cons: "Disgusting attitude from the flight attendant. She laughed at me when i told her i was transgender"

Pros: "Perfect"

Pros: "Lots of legroom in the exit row"

Pros: "The professionalism of the crew and the cleanliness was excellent!"
Cons: "The seats weren’t very comfortable!"

Pros: "All good"

Pros: "The seats were comfortable, the entertainment selections in the screen on the seat back were great, loved that there was more than one outlet for plugging in devices to charge, the sunset/sunrise lighting effect was really near"
Cons: "I honestly cannot come up with something that I did not lie"

Cons: "The boarding passes I printed out at home could not be scanned at the airport. This also happened last time I flew. There are words printed thru the optical."

Cons: "Airbus seems to have completely minimalized all legroom for persons over 6 feet."

Pros: "Friendly, efficient"

Pros: "Nothing"
Cons: "The Flight was inconveniently delayed and all they offered us were some cheap snacks and soda. I was completely annoyed by the whole situation."

Pros: "The mobile updates were helpful and timely."
Cons: "The overhead space was smaller on this plane and as I learned on my trip to DTW my weekender carry-on would not fit with my shoes in it. Because of this, I pulled my shoes out and put them in a collapsible bag that fit under the seat in front of me along with my small personal bag as I had done on my previous flight. However, the gate agent would not allow me to board the plane and would not listen to my explainations at all as I tried to keep the boarding process moving along. She kept repeating "you have 3 bags" and made me steep out of line and check my carry-on (which I would then have to pick up at baggage claim). When I asked why I couldn't get out on the jetway like she had done for other passengers she said, " I only did that for airline employees" (quick happened to be a flight attendant from Spirit). My overall experience on both flights to and from Detroit was that the gate agents and flight attendants were the most unhelpful and rude airline employees I have delt with and I will stick to my preferred carrier, Delta, for my future flights back and forth to Detroit. They certainly make me feel like a valued customer when I fly them, which I did not feel with American."

Pros: "Boarding"
Cons: "Wait for Baggage and 20+ mins getting to gate after we landed"

Pros: "Sears are comfortable and the entertainment is great as well."
Cons: "Not much to dislike."

Pros: "Comfort"
Cons: "Nothing at all"

Pros: ". ."

Pros: "Flight was quick- onboard entertainment (streaming videos to your device) was cool...but the back of the plane is pretty bumpy and there was a lot of turbulance."

Pros: "All flights were on time. American Airlines personal is extremely friendly"

Pros: "Everything was on time"
Cons: "Not enough room between seats"

Pros: "The least service I have seen among all the airlines I have traveled so far"

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: "It's pretty rare I can sleep on a plane, but I actually got some rest; very grateful for that."
Cons: "At 6'7", basic coach on a 737 is painful on the knees. I realize I can exit row for an upcharge, but that's kind of messed up, isn't it?"

Pros: "Friendly staff"
Cons: "They lost my luggage and that was horrible but they delivered it to my hotel which was nice."

Pros: "Seats were comfortable, the plane was clean, and all flights left and landed as scheduled. Actually, they landed and unloaded is early! Would recommend if you don't mind paying extra $25 to check a bag."
Cons: "That no checked bags are included in the flight costs. They didn't hide this or surprise me, but just a dislike."

Pros: "Getting bumped to First Class"

Pros: "The plane was clean, a/c worked well. Stewardesses offered food and drinks several times. Pilot repeatedly came over the intercom with updates on the flight."
Cons: "There was an annoying rattling noize coming from above my seat near the roof and wall."

Pros: "Loved that he was upfront with all of us that it would be a bumpy flight after about 20 minutes, which he was correct and very accurate."
Cons: "I thought his delivery sounded a little more "worrisome" than it needed to be. I thought that he could have expressed the same sentiment, while sounding more confident in his ability and more soothing for folks like me who despise turbulence:)"

Cons: "Little planes need an interior restoration to make them look better."

Pros: "The flight crew was friendly and smiling."
Cons: "The seat in economy was incredibly uncomfortable. Seat had a slight forward incline which made a finding a relaxing position impossible."

Pros: "The flight attendants were nice enough and the snacks/beverages were average/as expected."
Cons: "This flight was delayed for more than 2.5 hours and the communication was poor. The gate agents weren’t helpful. The airport didn’t have enough outlets. Or chairs. My flight out to this location was also delayed by over three hours. At least they tried to make us feel better by telling us what was going on. The staff at the airport were rude and unhelpful and United airlines is unreliable."

Pros: "Yes"

Pros: "Seat good, boarding good"
Cons: "It was terribly cold, was not even offered snacks, the one steward was chomping on his gum very unprofessional on checking in"

Cons: "I didn’t even make this flight!"

Pros: "Crew was friendly and helpful. Inter Seat spacing was not convenient."
Cons: "Ensuring seat in front of me was fixed to ensure it doesn’t over recline"

Pros: "Crew were friendly. The entertainment system they have was excellent. Plus gave out free ear buds, cheap ones I’m sure but still free."
Cons: "The leg room on this flight was very tight. I’m a short person and it was still very tight and uncomfortable."

Cons: "It took 45 minutes for the luggage to arrive at the carousel, and they sent it to the wrong carousel. Not sure if it was at the other one the whole time, or just took that long."

Pros: "Nice flight. Easy check-in and boarding, friendly staff"

Cons: "We flew dtw to Frankfort we"

Pros: "That we didn’t get harassed"
Cons: "Lack of entertainment if you didn’t bring a device. Even if you did needed an app for it and the United WiFi was incredibly limited and slow Staff could be friendlier instead of impersonal"

Pros: "All I got was a $20 food voucher for a 9 hour delay and missed meeting."
Cons: "All I got was a $20 food voucher for a 9 hour delay and missed meeting."

Cons: "We were delayed in Detroit due to deicing the plane. We landed in Houston late. They let us and a few other couples off the plane first so we could make our connection. We sprinted off the plane and arrived to the gate two minutes after they closed the door; plane was still there and they would not let us on. United knew we were coming and they closed the door anyway. The next flight out to Liberia, Costa Rica wasn’t for two more days. They ended up rebooking us on a flight to Panama which had a connection to San Jose, Costa Rica. Much farther of a drive from that airport. Very disappointed in how United handled this situation, we were told if it was a bigger group they would have held the plane for us. I will never fly United again but I know it has nothing to do with Kayak. Kayak has always been great and is my go to for booking plane tickets."

Cons: "Cancel my flight I had to buy my own hotel room"

Cons: "We were supposed to leave but had to wait on the runway. And I was a little cold , and the air was stale. Other than that it was great."

Pros: "Great trip only 1 stop no layover"
Cons: "Comfort of seats loading and unloading plane"

Pros: "Good"
Cons: "Nothing"

Pros: "Nothing"
Cons: "We wasted six hours at the airport to find out we would not get to our first destination in time to catch our jointing flights. Then they had to rebook us the next day and our luggage it was sent to Chicago . It was not a good experience at all just very frustrated and we missed a day of vacation"

Pros: "The touch down was smooth."
Cons: "Revise your website to state accurately of the luggage allowance. I watched the people in distress because their carry on was a little too bulky."

Pros: "Smooth and friendly efficient crew."

Pros: "Nothing I won't be flying united again!"
Cons: "The lady at the gate when boarding was not friendly and was not willing to help us get seats together. I was traveling with my mother, husband and two infant children. And it was like pulling teeth to get any information out of her. She did not even tell us we could board early to get situated on plane! I also called earlier that morning and spoke with a man on he phone at united who told me he put us all in the same row. That was a lie bc when we checked in at the gate to get our seats the lady said no one was sitting next to each other! That lady was rude and short tempered! Awful experience will never fly again!!"

Pros: "On time, comfortable but crowded"

Pros: "Nothing"
Cons: "Almost didn't get a seat."

Pros: "It's annoying that you pay for seat upgrades and they stick ya in group5 boarding. It's just reminds people that they want to charge you for every little thing they can these days!"

Pros: "Everything was smooth from boarding to deplaning. On-time departures and arrivals."
Cons: "Wish seats reclined and electrical outlets present for charging."

Cons: "4 hour delay"

Pros: "Efficient, professional and speedy service"

Cons: "It was so late it left me in the lurch and ruined my week"

Cons: "There was only one person rescheduling and we got a faster reroute get plan on the phone. It was all pretty awful and we did not get to our destination until many hours after scheduled. Not at all a good trip."

Pros: "The staff were excellent ! Great attitudes, great personalities,very informative staff and pilot!!"
Cons: "Both flights were delayed!"

Pros: "Relaxing"

Pros: "I liked how we were kepted informed of the delay."
Cons: "The delay but weather was bad so it is understandable."

Cons: "Seats are a bit cramped"

Pros: "Ontime"
Cons: "At least one check-in baggage should be free for the price."

Cons: "No cash food and beverage"

Pros: "Everything"
Cons: "Notthing"

Pros: "The crew was always striving to make sure the flight was as comfortable as possible. They have me a couple perks for being in the military and that made my flight very enjoyable. I will definitely start flying with United more often"
Cons: "No bad comments on my behalph"

Pros: "The flight was not fully booked so there were plenty of empty seats for everyone on to spread out."
Cons: "The flight was minorly delayed for de-iceing, but not more than maybe 30 mins or so. Not even worth saying what I didn't like about the flight when its necessary!"

Pros: "Everything went smooth and on time."
Cons: "Plane was small and the space felt a little tight but was not too bad."

Pros: "Seating was comfortable."
Cons: "The plane departure wa two hours late leaving causing missed connections. There were two United employees at the counter and one left. They were to help us change connections so te line was long and VERY slow. Half of us didn't get the connections changed. We de larded in Houston with connections that were unreasonable. United employees rude and not helpful. I had to fly to San Francisco then to Ontario making a long terrible day."

Pros: "Everything was perfect, from the boarding process to the seats, things went well."
Cons: "Nothing."

Pros: "They could not land in harlingen because of fog so they took us to Laredo (3hr drive away) where we sat on the tarmac for about 40 minutes. Then told us we were going to mcallen (35 min drive to harlingen). Then told us United refused to provide transportation from mcallen to harlingen so they couldn't take us there. They announced we were going back to Houston to wait on the next flight tomorrow, and that they would not pay for hotel or meals because of a weather cancellation. Everyone on the flight wanted to go to mcallen even if they wouldn't provide transportation but they refused. So the majority deplaned in laredo and paid for rental cars, getting home about 6 hours after scheduled arrival. Only perk was that the flight attendants were really really great."

Cons: "The customer service was horrible and I was stranded for two additional days."

Pros: "Not a damn thing."
Cons: "My flight was held back 2 hours because "a flight attendant called off". So I missed my connecting flight "I touched down as the connecting flight was supposed to take off". I was put on a standby list for a flight leaving later that night and I didn't get it. I was told I had to wait until 7am the next morning to get on a flight. After asking, I was given a hotel, cab, and 2 food vouchers. The taxi took me to the hotel united chose. I got there and there were no vacancies. I had to pay for my own taxi to a different hotel that luckily took my voucher for the other hotel. after all this mess I only got 2 hours sleep. The 7am flight waited for its connecting flights. This delay cost me a third of my trip and money on my first night at my hotel."
