Pros: "Friendly crew"

Pros: "The crew was amazing! The seat was comfortable."
Cons: "Used the self check in kiosk to begin! That was awesome! But after that I still had to stand in line to check in my bags. That part of the process took a bit longer than expected."

Pros: "Son got wings, so was happy."
Cons: "No entertainment."

Cons: "It was all good ✈️"

Pros: "The crew was so nice and funny!"
Cons: "The food could be better, but I understand ultimately what it is: mass produced. The pretzel bread is good. The chocolate chip cookie is great. The ice cream is great. The lemon and something cheesecake dessert was too lemony for me, but my mother would have loved it."

Cons: "The coffee could’ve tasted better."

Pros: "Nothing special"
Cons: "That was the most uncomfortable and cramped seat I had ever had on a plane flight. Even sitting on the pillow did not help."

Pros: "I like that I arrived at my destination safely."
Cons: "My allergies were bothering me due to the airlines allowing animals to travel as passengers, in this case a rabbit. I am very allergic to animals. My breathing was compromised."

Pros: "The flight crew was as positive as possible."
Cons: "It was very late"

Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."

Cons: "The flight was 2 hours delayed.. this cause a lot of inconvienece.."

Pros: "Nice crew"
Cons: "Late flight due to ground hold EWR. Two screaming kids immediately behind me."

Pros: "Delta was OK"
Cons: "Lack of attention by the fly stuard in Virgin Australia Virgin had a 45´delay"

Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."

Pros: "Comfortable seat for a short trip."

Cons: "Flight was delayed out of St. Louis causing several of us to miss our connecting flight from Salt Lake City to Portland. Delta was of very little help in assisting us in making a connecting flight. They could have at least helped with travel arrangements and provided us with a little food, a pillow and a blanket as we waited in their terminal for the next flight on their airline which was a several hour wait. I understand these things happen but the passengers didn't cause the problem and Delta needs to take care of people better if they expect to earn repeat business."

Pros: "Timeliness, easy trip"

Pros: "The crew was nice."
Cons: "This was an older, smaller plane and it had more leg room. Appears I’ll have to start checking Delta to see what birds flying the leg."

Pros: "Delta gate agents kept everyone well informed and updated as to new boarding time/procedure"
Cons: "Flight was delayed by 4 hours and reason was not explained or obvious"

Pros: "Nothing."
Cons: "This is the second flight in a row in which Delta has either cancelled or rescheduled my flight at the last minute. Last time I was stranded in the Atlanta airport overnight waiting literally all night for them to return my luggage (which never came, and then was late even to my final destination). I will not be using Delta in the future."

Cons: "Ac not working at last 30 minutes of flight."

Pros: "Nothing"
Cons: "We lost our whole vacation and had to pay for the plans fare twice because My last name was spelled wrong on our tickets and we were unable to use them because my passport didn’t match the name on the ticket. We had to rebook everything pay almost twice as much for the plane fare, our Lodi g cost more and our trip was delayed for two weeks. Vyama is blaming us for spelling our name wrong and claimes that it’s our fault this happened because everything is automated. There saying they don’t touch anything that we enter into the booking but somehow everything they claim we entered is now in all capital letters and the space between our first name and middle name is now gone and all run together. The coustomer service number gets you to someone in India. I have tried to get this addressed four times now at first they tried to place the responsibility on the airlines now us and they have hung up on me twice. Kayak has been worthless, they also just pass the responsibility on to someone else. We will never use them again ant I intend to make sure that this mess is put out in social media to hopefully keep others from having their travel plans ruined by their flawed system."

Cons: "They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware"

Cons: "Seats diddn't recline - often ignored by flight crew."

Pros: "In flight movies"
Cons: "The flight was 3 hours late taking off which made us miss our connection to chicago so we are stuck in Atlanta tonight with unplanned expenses we were not planning on!"

Pros: "We made it it was short 1 hour 11 min"
Cons: "I had a long lay over it was more then 12 hours"

Pros: "Friendliness, spirit, organization of crew."
Cons: "The obvious- no leg room, no food"

Pros: "Very friendly crew"
Cons: "Seatbelts very short given ample seat size"

Pros: "Everything from the check-in to the landing was great. We were well informed about what was going on with out luggage (we were on a regional flight) and the assortment of free snacks were superb! I guess I'll be a returning customer"
Cons: "I was expecting some form of entertainment (radio, overhead monitor, etc) on the CRJ700. But it really don't take away from the experience since T-Mobile partnered with the Wi-Fi service and I received a free hour of Wi-Fi!"

Pros: "The entertainment"
Cons: "We didn't get our seat assignment until we got to the gate. Attendant said it was because tickets bought too close to take off don't get to pick seats, but we bought our tickets about three weeks before. Also, my boyfriend and I sat in a full row while the row in front of us only had one person. It would've made more sense to put that person in one of our seats and us in that row to give four people more space instead of just one."

Cons: "My flight got to New York so late!!!! I missed my international flight."

Cons: "Not great communication from gate or staff on board. Failed to provide adequate water. No ice on super warm flight. Just bad experience overall."

Cons: "Nothing."

Pros: "Newer plane! Comfortable"
Cons: "Nothing just great"

Cons: "Not enough water on the flight and we landed in a parking lot and shuttled back to the airport."

Cons: "turbulance"

Pros: "All went well"
Cons: "Nothing"

Pros: "I was cleared for standby! Flight attendant at the stl gate is always friendly and willing to help! I love her!"
Cons: "I waited almost 6 hours on the phone the night before the flight to get on standby! Almost didn't get the flight! Was charged $50 only to not get on my next flight because it was over booked! Flight attendant was very rude!"

Pros: "I liked that I was able to get able to get an earlier flight!"
Cons: "I don't like that I had to pay $50 extra dollars for standby on both legs of my flight! I am a very loyal delta customer and these past times flying I feel like my favorite airline is turning into the bad airlines delay everytime, problems with the plane fare prices too high! I'm starting to think about taking my business elsewhere!"

Pros: "10 minutes early departure"
Cons: "There isn't enough seats in the gate area and sitting on the runway for 10 extra minutes we could have been early"

Pros: "It was great and very roomy I felt like a movie STAR!!!"
Cons: "N.A"

"Status notifications"

Pros: "American Airlines ancient crew could not be bothered"

Cons: "Don’t delay all your flights American Airlines. They are never on time."

Pros: "Kind staff. Nice, newer aircraft"
Cons: "Copilot was changed/ not on time and delayed the flight by half an hour. Also, sat beside a man who was far too large to be in a single seat with hygiene issues he clearly was unaware of. Made the 3 hr flight very uncomfortable."

Cons: "Nothing, great job"

Pros: "It was quick, on time."
Cons: "Beverage service did not exist."

Pros: "The flight was on time."
Cons: "The seats are absolutely horrible. I feel crammed like a sardine in the plane. Seriously, can we adjust the seat widths and distance to the seat in front and make them a couple inches bigger?"

Pros: "The seat was cormfortable and the entertainment was dope!"
Cons: "Communication. The pilot did not say when he was landing and considering it was a rough landing it would have been helpful to say. He said we shall be landing like 40minutes before Then quiet"

Cons: "Potentially of hiccups and things outside of AA control. Better, more comfortable seats would be nice."

Pros: "The access to a movie while flying was great to help pass the time."
Cons: "All good"

Pros: "great entertainment"

Cons: "There was no movies in flight while returning back"

Pros: "Wi-Fi and USB ports worked great. Seat was comfortable after 11 upgrade. On time."
Cons: "Having to pay extra for a aisle seat"

Pros: "The only good thing about the flight was the crew."
Cons: "I’m surprised there weren't chickens and goats flying with us. The seats were worn out and ratty. There was no where to charge a phone or electronics. No in seat tv screen so was forced to watch the tiny overhead screen of terrible tv shows and mediocre movies. I prepaid for a seat a head of time which was given to someone else. Also quite a bit of heavy turbulence the entire flight. Not ideal for an 8 hr flight. I’m lucky I brought an external charger and some xanax. Never again"

Pros: "The American airline is a wonderful experience especially during a stressful time to travel. Everyone was helpful. Especially the pilots. They help me order my Uber."
Cons: "The hostess was a little short but she was working alone, Thank you for sitting in front of plane."

Pros: "Worst flight crew in business class ....super lazy"

Pros: "Newer plane, wifi worked well, coffee good, not sure if it was on time, but it didn't matter to me. Friendly crew. Smooth flight."

Cons: "No backseat TV or usb charging outlets"

Cons: "Flight was delayed 4+ hours due to weather. Gate agents did not communicate well, were rude and not helpful."

Pros: "Entire flight crew was friendly and helpful!"

Pros: "I really liked crew, fast boarding"
Cons: "Old airplane, very noisy , no tv screans on seats, boring movies on tv and horrible ear sets, could not hear anything. very dissapointed experience."

Pros: "I decided to travel First Class from Houston TX and that was the greatest choice I ever made. IAH requires travelers to arrive 2-3 hrs early due to traffic or weather conditions. I checked in at 2 pm and waited for my 5 pm boarding call. First class was amazing! I stored my belongings without any issues. I sipped wine and dined on pasta and watched the movie Father Figures with Owen Wilson and Ed Helms. The stewardess was polite and friendly. The food was enjoyable and the passengers were friendly. The bathroom as also immaculate, I was impressed."
Cons: "No complaints!"

Pros: "The entertainment system was nice. The cabin crew was nice."
Cons: "Airlines have gon back to the days of packing as many seats as possible into these planes. I not a big guy but not huge. I’m just over 6 feet. When I sat down it was impossible for me to sit without my knees jammed against the seat in front of me. I ended up switching with my daughter to the seat across the isle which had slightly more leg room. Overall the seating was very uncomfortable."

Cons: "Our flight was delayed and I missed my connecting flight, causing me to be much further delayed coming home. Spent all today miserably tired at work. I also sat in front of a very obnoxious man who was very loud and no body was telling him anything about video chatting on his speaker phone during take off."

Pros: "The whole crew was amazing! The food was actually decent and nicely warmed. Everyone was really friendly and the on-flight movie selection was great."
Cons: "Truly an awesome flight. I can't think of anything that they could have done"

Pros: "Food was good, crew was friendly."
Cons: "The 90 minute delay before take off."

Pros: "Arrived ahead of schedule."
Cons: "Some crew were not very welcoming (smile)."

Pros: "The flight was good, as well as the attentive staff"
Cons: "Kayak messed up royally by saying this flight was an Iberian. We went to the Iberian terminal as the email I received said the flight was an Iberian. After waiting on line for twenty minutes we were informed that this changed to an American Airlines/ British airways flight. We had to AirTran to the next terminal and almost missed the flight. Kayak needs to keep their customers better informed."

Pros: "I haven't flown AA in a while, I was impressed with the entertainment and food!!! They had a variety of movies. Also, the food was simply but delicious! Cheese and fruit!"

Pros: "Comfortable seats, attentive staff"
Cons: "More non dairy food obtions"

Cons: "Crew not that friendly towards everyone."

Pros: "How nice the crew were through it all was great! Flight to D.C. was smolth too."
Cons: "Because of the fire in the Tower, all flights in the DMV area were cancelled that evening. I was unable to go to work the following day having to request off sick."

Cons: "The touch screens were less than responsive. They weren't very touch sensitive."

Pros: "Nothing in particular. They got me there."
Cons: "The usual stuff. Uncomfortable. Worse than riding a bus."

Pros: "Flight was quick, seamless, on-time, and comfortable. WiFi available. Arrived 10 minutes early. Recommend the shuttle because if you don't get one flight, they'll get you on the next. These days, the shuttle is more dependable than Amtrak."
Cons: "Would appreciate a USB port or an outlet."

Pros: "First class flight attendant was awesome!!"

Pros: "Everything about the flight itself was excellent"
Cons: "Could mother on an online boarding pass from BA (ticked on) or AA ( flight operator)"

Pros: "2 flight attendents reset the unit but to no avail."
Cons: "We could not resolve it."

Pros: "American Airlines has alot more commodities than most"
Cons: "Alaska sold passengers to American"

Pros: "on-time"
Cons: "crowded, tight even in better seat, no wifi entertainment"

Pros: "This time every thing excellent"

"Easy flight & quiet!"

"Boarding gate door was closed on connecting passengers and we missed this flight"

"Everyone was very helpfull with bording."

"Bad information from Kayak. unhelpful and confusing."

Pros: "Grew was amazing."

Pros: "Excellent experience & return flight on airbus plane was fantastic, reduced flight time by 1 hour. Great trip, thank you United Airlines"
Cons: "All great"

Pros: "Flight was quick and easy"
Cons: "Seats are small. Luckily the flight is short bit for anything longer than one hour I do not recommend this aircraft"

Pros: "Price line is better not thief like you yu take my money for nothing my husband not traveling your given me fake tickets . bring my money back on my account. am gonna take to court yu fukin beach.yubstolen my money"

Cons: "Multiple people on flight not wearing masks"

Cons: "No bad, easy"

Pros: "The boarding process was good. Departed on time and arrived on time."
Cons: "No social distancing of passengers on the plane yet there are empty rows of seats."

Pros: "One passenger was removed from the plane after 3 times he was warned about removing his mask before takeoff. Due to Covid19, United was boarding by row, from the rear to the front."
Cons: "When I made the original bookings, United was not allowing the middle site of the row to be used. Unfortunately, the plane was almost packed. 8 seats in the rear were empty."

Cons: "United Airlines in our experience runs late putting a lot of pressure on any ongoing connections . Not clean . Staff not friendly . Only sometimes helpful."

Pros: "Nothing, to be honest."
Cons: "Terrible boarding process (boarding groups one and two together for the first time, so even though we were group two priority, we did not get on until the middle of three and no overhead bin space left). There was no snack/beverage service. We did get a tiny bag of pretzels and were supposed to get either water or juice, but we never saw a beverage. Also, my seat's entertainment did not work. The worst was the HORRIBLE TINY ECON SEATS!!! Unless you are a child or a small woman/man, I would avoid this flight if at all possible. I have never been so uncomfortable on a flight, and I fly a dozen times a year for the last 25 years."

Pros: "I liked everything was excellent"
Cons: "There was a 10 minutes delay"

Pros: "Nothing!"
Cons: "Kayak sent me a message that our connecting flight out of O'Hare was boarding at gate B5. However, checking the monitors in the terminal showed the correct gate was B21, which is on the opposite end of the terminal. I don't know why Kayak had the wrong information on this. We barely made our connecting flight because our starting flight was over 30 minutes late, which was United's fault. This made rushing to the correct gate for our connecting flight all the more stressful. No time to stop at the bathrooms or pick up something to eat. Both United and Kayak let me down on getting back to Hartford. We arrived at the end of boarding with no room left for our bags in the overheads so we had to check them and pick them up at the carousel. A totally BAD flight experience."

Pros: "TV and movie choices should be according to 2018 instead of1980. Also TV should be from running Era"

Pros: "My trip started off with airplane problems from the beginning. From my flight being delayed multiple times by air china to the overly packed united to the confusion of the non updated confirmation numbers or the e-ticket number. Even on the day I left upon arriving to the airport my confirmation number they had just given me after all the prior problems still didn't work. Air china had mediocre food with okay entertainment except my headset jack on the TV was broke and I couldn't watch anything. On the last air china flight from Bejing to Bangkok. I couldn't even charge my phone, watch any entertainment and basically was just stuck with no WiFi. Justfly wouldn't compensate for the changes on their end and said I myself would have to ask the airlines for compensation which the.the airlines directed me no where for compensation or even to upgrade my seat. Now I'm finally in Thailand but I'm scared of my return."
Cons: "Everything was really not great. Air china had mediocre food that some of it wasn't bad but other was so so."

Pros: "Nothing"
Cons: "Pilot admitted error. They did not even know what was going on. 3 hours late due to last min maintenance after the plane had been on the ground since last night. No supervisor came even though we asked the captain to contact one. We were ignored. Total clusterfuck. Pilot was courteous and professional but front desk was Frazzled and incompetent. We were hugely inconvenienced and missed our obligations with no offer of compensation. Then when we finally get on the plane they kick us off!!!!!!!!!! Now they are saying a 630 departure for a 2 pm flight. This is beyond acceptable and I am about to call the local news and am sending them video of your gross incompetence. I want to be contacted at 815-527-1935 immediately. My time is valuable and no part of this delay is acceptable. I want full flight vouchers for this debacle"

Pros: "Captain and crew were brilliant, kept passengers informed throughout as to the delays, as a result all passengers were patient and understanding. Not much more could have been done to improve the experience as the snow and conditions at Dublin airport were out of their hands."

Pros: "My husband and i we want to seat next to each other"
Cons: "1) Chicago O'Hare Airport Airline staff very rude. 2) from Los Angeles to Chicago my husband and i are not sitting to each other. My husband is upset. 3) from Chicago to Los Angeles my husband and i are not sitting to each other. It happened again. Very disappointing. We think the airline doing this intentionally."

Pros: "The price was unreal so I had to jump on this, I was able to get on and off with my backpack no problem. The flights were good, captains were very communicative about times, expectations and when turbulence was present."
Cons: "The check in had to be done in person because of the need to check my bag size, I felt a little insulted that I would have to be checked on my honesty. When I got to the check in it was like watching a special forces team measuring and prodding peoples bags to get them in to the little box even when the shapes were the reason they couldn't fit, not the size of the bags. I literally watched someone fit their bag and the attendant take it out and make it misshaped for the box and show how it didn't slide in. I had no issues with my luggage, but that sucked to watch happen to others. The food and drinks came about 10 minutes before the plane landed."

Pros: "The crew The entertainment options The power options The drinks"
Cons: "10 minutes earlier and the food would have been better. Then again, 10 minutes earlier and wouldn’t have made flight."

Pros: "Crew help and service"
Cons: "Lending was bumpy. , Internet was not Working and no entertainment chenal as well"

Pros: "They got my vegetarian food order right"
Cons: "Old airplanes both there and back, we had a choice of a few movies on a TV that we couldn't access on demand so you had to start half way through, and the quality was appalling. We were supposedly promised we could stream onto our devices via wifi but this didn't happen"

Pros: "The flight crew was attentive and polite."
Cons: "Though not the fault of the crew or airlines, we were delayed almost 90 minutes because a parent took their toddler into the lavatory while at the gate and they messed it up and plugged the toilet with paper towels and/or pampers. This was after I had a 8-1/2 hour flight from Copenhagen, Denmark. Also, the seat space and amenities are so inferior to international flights. The narrowness of the seat and closeness of the rows makes it hard to be comfortable. After being treated to two meals on the international flight, one small two-inch bag of snack mix is almost pointless."

Pros: "It got us from a to b but not much more to be said!"
Cons: "The idea of the entertainment system broadcast to your hand held device is fine - it didn't work for me though."

Pros: "Helpful finding next flight worried can my son it UN traveled and is in a standby I pray he gets on this flight I am really worried. If he does he will arrive at 11:45 pm if not .... I have no clue he is so young and scARED TRACING ACROSS THE Whole country. For mistakes beyond his control saying prayers."
Cons: "I was tied to go tailgate 10 like my paper said they switched flights to gate 15 missed flight had to wait 7 extra hours flying Into Chicago and have a priority stand by pass from Chicago to Knoxville. I need to be on this flight so bad. If I dont make it i have no clue what i will Do. I need to keep my stress down and just prY i get on this flight which would have me i. Knox about 11:30 pm if not i have no clue what to do.the United Team we have talked to have been nice they just can't confirm my Chigaco flight to Knoxvile and i have 31 min. Once plane lands to get to other boarder term and Al."

Cons: "Such a downgrade from other airlines! Awful! They board backwards. Usually the back seats board on the plane after the special needs people. Makes more sense, people are out of the way. My water was poured into a cup from a big water battle. I like how Jetblue gives me a personal water bottle and a variety of snack option. I was given a "snack mix" on this flight which was not good. I hated this flight and there were NO televisions, or usb ports to charge phones. Never again. They didn't even have enough room for carry on bags for everyone. Thank god I packed light and didn't need to use that option. Good to know United Airlines has crappy everything."

Pros: "I liked that we arrived on time and that the entertainment actually worked properly."
Cons: "I didn't like the fact that my husband and i had one option only and that was Indian vegan vegetarian dish. We were told that's all there was left. We gave back our tray. I don't mind going without food for a flight but my husband had surgery die to diverticulitis and can only eat certain food. The flight attendant said that she was going to check if there is anything left in first class but it took for ever and I become impatient as the light were turned off and people were getting ready to sleep. So I switch on the light and another flight attendant came by. I explained the situation but she came back with the same Indian vegetarian dish we turned away. After more frustration and explanation the Stewart came with the. Hi Ken version. I gave my husband my share and he was able to finally take his medication and eat the chicken with the bread. I only ate the ice cream and had a glass of wine. Later on the first flight attendant who served us the meal came with a couple of oranges and a bag of chips. Saying she got this from first class. I kept the oranges and gave her back the chips. Floghing with United is very disappointing to put it mildly."

Pros: "There was a good entertainment system with a lot of new options."
Cons: "My itinerary said I fly on Brussels Airlines on a specific flight number. I went to the international terminal to discover it is not there. I then asked multiple aiport staff members if they heard of Brussels Airlines and they said they did not. One person said it may be terminal 1, so I went there based on very little information and with hopes it would be there. I got to terminal 1 to discover there is no Brussels Airlines. I walked to Lufthansa because my return flight is through them, but it was not there either. At this point I have 45 min to make it through security and board, and no one can tell me where Brussels Airlines is. The good news is the flight was delayed, and I got an email from United Airlines with the flight status. This is the first time I was contacted by United and there was a completly different flight number than the itinerary. United should be more clear on the airline and terminal information for international flights!"

Pros: "Nothing!!! It was handled in a terrible way"
Cons: "The way they didn't care"

Pros: "From what I encountered at the crack of dawn this morning... The staff handled somnolent, irratable passengers in a full capacity 757, with nothing but unwaivering efforts and kindness. (shrieking baby temper-tantrums, service dogs, and people allergic to service dogs included) Even while dealing with the most self-entitled, disappointingly inconsiderate individuals, the flight attendants kept their composure and remained understanding, professional and accomadating. As for that rude, pompous pig of a woman up in front.. try and remember we're all human here and you should attempt to treat others like so. I can't imagine the staff being particularly fond of the idea of spending an hour delay with your continuous, huffy bitching in their ear. (as if they have any control over the situation"
Cons: "Me and my boyfriend's seats were separated on both flights.. apparently it was in the fine print.. I don't know :/ kind of sleasey, kind of lame. Be transparent. Luckily, met a great guy who had no issues switching! :)"

Cons: "We reserved wheelchair assistance prior to the flight. We had to wait an extended amount of time to actually get the wheelchair assistance with 5 kids 7 and under. Due to the wait we almost missed our flight, we were literally the last to board the plane. We were hoping to grab some breakfast for the kids as we had a long flight and did not have time to do so because of this delay. This is why we called ahead to reserve the wheelchair. The people checking in did not seem to care about the delay and only told us to be patient. Sad, unfortunate experience with accessibility issues."

Pros: "Crew. Aircraft selection."

Cons: "several people assigned to the same seats, mine included. lots of last minute moving around."

Pros: "Some of the people I dealt with were nice. All of the flight attendants and pilots were nice."
Cons: "United only had one person working to check people in, and due to a lady with 8+ bags that the only agent had to take 20+ minutes with (while the line stacked up behind us), we ended up missing the first leg of our flight. Told us our bags would be checked all the way through, and they weren't. Checked bag got lost on the way back (again, due to misinformation from United on whether our bag would be checked all the way through), and when we got them back they had obviously been rooted through, with no note left by TSA. I fly often, and this was one of the worst flying experiences of my life."

Pros: "I didn't like much. The employees were great and that's about it!"
Cons: "I've only flown with United for four flights. And of those four flights they have been delayed for three of them. To be specific about this flight, straight off the bat the flight was late due to a late arriving plane.. Understandable. Then to top it off they had no pilot. So then the 1.5 hour delay has now turned into a four hour wait. But I'm still waiting for the flight so the wait could be even longer yet. The airline should consider refunding everyone's money on this flight. An hour delay is one thing, but four hours is uncalled for. Never flying with United again."

Cons: "Delay and then having to change gates - at O"Hare that means walking and walking some more !! After being insulted during check in. The RUDE woman (poor English) with assisted boarding then the RUDE man that changed my name and my luggage he chose to send to Dayton OH -never been there in my life and he "dug" thru my luggage - as if he was searching for MONEY or GOLD -he pulled out a protein drink and I asked him to hand that to me so I could drink it as I am a diabetic - he shouted at me "I THROW AWAY'. During the two hour delay I could have used it !! Poor service I will fly American from now on !!!!!!!!!!!"

Pros: "Crew staff went out of his way to find something for my aisle to snack on when the person next to me asked if there was any snacks on the plane. The plane had to be changed for another plane due to a mechanical issue on the first plane, and the new plane had not been stocked with food after it's previous flight, yet the crew member was able to scrounge up some snacks for us! Also got complimentary directtv - nice, but doesn't make up for not getting home in time yet again."
Cons: "United sucks. I have flown it maybe 10-12 times in the past 2.5 years, mostly back and forth between Chicago and Boston. I have had only 3 round trip flights go without a hitch. Every other trip was delayed. This time 4 hours on my return flight to Boston due to a plane switch, boarding of a new plane to discover a mechanical issue, deboarding, waiting for a new plane, then boarding and sitting on the ground for another 40 min before we were able to take off. I was delayed 1.5 hours on the way to Chicago due to another plane swap (no joke). Still doesn't top but my worst 5 hour delay in Chicago on the way back to Boston because the captain didn't show up. United is atrocious and is my last choice or any airline. Only fly when I'm absolutely forced to now due to no other reasonable choices. They are below delta, JetBlue, American, southwest, and embarrassingly, spirit as well. Terrible."

Cons: "We were connecting to this flight after flying in from Rome. Initially we were scheduled for an 8:30pm flight, but after landing early asked if we could change to an earlier flight. They graciously bumped us up to a 7:30pm flight, which trimmed our 4-hour layover down to 3pm. Cut to 6:15pm...we find out that the flight is not delayed AN HOUR due to a "late inbound flight." Long story short, the 7:30pm flight ended up departed later than the 8:30pm flight we were originally scheduled on so we didn't get to LA until after we were originally supposed to!!"

Cons: "While happy to have pilots concerned about my safety, it was frustrating to suffer thru 2 different mechanical delays. The first one was a missing rivet - which turned out to be so bad they had to put Us in a different plane. Then, that plane developed some mechanical/software issues as we were taxing. My 3-hour flight turned into a +5.5 HR endeavor. When you are on 2 broken planes in a row with the same airline you start to to wonder about how well they are maintaining their equipment. I feel like I deserve more than a "sorry" for the use of my extra time, but no credit or flight certificate was forthcoming."

Pros: "It left on time and arrived earlt"
Cons: "I was seated in a window seat and another woman my size about 110 pounds was seated in the aisle however there was a 400+ pound man sitting in a middle seat which made it very difficult for me especially to even sit back because it was touching me the whole time when you have somebody of that size You should make sure they are on and I'll because then the find attendance would have some difficulty getting through instead of your passengers being inconvenienced either that or force people of that size to take two seats"

Pros: "First of all, the crew was amazing. I had just been traveling for about 20 hours and I had a seat towards the back of the economy section. After traveling that long, I was getting antsy to be at my destination, and I asked the gate agent if she could bump me to a row towards the front of economy- thankfully the plane wasn't full, and she was able to! It's the little things like that, that are what make me fly United. Also, the cabin crew on the flight was great! Of course, the economy section of the plane wasn't an ideal amount of space, but come on- it was an hour flight, and they did a good job of trying to spread people out so that the rows weren't packed."
Cons: "Boarding took a little longer because the plane was being cleaned. I believe they said the overnight flight got in a little late and they still had to clean the plane. We boarded late, but still got to our destination early. Negative turned into a positive- you can't beat that!"

Pros: "Quick flight."
Cons: "Flight was delayed for 40 minutes because of "paperwork" according to the pilot. We boarded the plane on time however had to sit on it during the delay. We were not informed of what was going on until we had already been waiting for 30 minutes. When they informed us of the delay they offered everyone free direct TV in flight to make up for the delay. Once we finally took off they announced that the direct TV was not actually working. The flight attendant making the announcements was not sincere and rather unprofessional. Luckily the pilot flew fast so we ended up arriving only 10 minutes late."

Pros: "We received a free video service for the flight"
Cons: "First of all the flight was booked for a plane which was too large to land in Providence. So either way we were going to have a longer day and extra leg.....which I only paid for ONE plane change. After running to the gate because my first flight was late taking off, this flight was delayed due to engine issues. The agent had us standing in line for 1 1/2 hours while she tried to figure out what was going on. So instead of taking off at 5:40 pm, we took off at 9 pm and still had to catch a bus from Boston to Providence...HORRIBLE Flight = Long Day/Night"

Pros: "The fact that you serve a small complimentary drink and snack on such a short flight was extremely appreciated. It seems most airlines either won't serve on a short flight or charge you extra. Also, I absolutely love the new seats on the planes you guys have been using for quite a while now. They're much more sleek/minimalist so they don't take up as much room. As a disabled person, the bulky seats still employed by many planes on other airlines are incredibly hard on me getting in and out of the seat isles. The crew was very efficient and kind. I also appreciate the thank you to military personnel that they announced at the end of the flight."
Cons: "My gate was moved a few minutes prior to scheduled boarding. It was a minor inconvenience. Flight was a bit late getting out, but still arrived at designated time. Complimentary Wifi would be pretty nice, but not expected."

Cons: "Lack of communication. Kept us belted down for s very long time. Lacked food service, lacked water service till the very end of the lock down. Then we were given the option to leave the plane as the doors were to be disarmed. But if we did the plane could get clearence and leave with no warning. I missed my connecting transportation, had to scrape my weekend plans, currently searching for a place to stay tonight while they locate my bag. I am cold and left my jacket in my bag. The United counter people are blaming it on the weather. I am sure everything was delayed by the laxadaysical baggage loader. The one person ( or lack of help loading the bags on the plane completely altered my travel plans. I requested assistance for hotel only to be told they are full when in fact several are vacant on the Internet. I should of videotaped the baggage loading in Canada, it would of went viral."

Pros: "The crew on United was very helpful on my July 2 flight"
Cons: "You sold me a ticket on Lufthansa. When I got to Charles De Gaulle airport in Paris I waited 45 minutes in line to check in with Lufthansa. When I got to the counter they said they had no record of my reservation. When I showed them the Lufthansa reservation they told me it actually was for a United flight, even though it clearly said Lufthansa . I had to wait another 45 minutes in the United line to retrieve my boarding pass, then about another hour to go through passport control and security. I barely made my flight. I will never make a reservation through Kayak again. I am deleting your app."

Pros: "Punctuality"
Cons: "Food. It is a very long time and there no food enough"
