Airline reviews

Cons: "Purchased food on board. Dry and unappealing."

Pros: "The food and drinks were so lovely, it felt like I was in first class rather than the cheapest economy seat. Great entertainment selection and comfortable seat that let me sleep well."

Cons: "Over a month ago I requested a seat with extra leg room due to a documented medical condition. My request was not granted and I was in pain most of the flight."

Pros: "Great crew, early arrival"
Cons: "Old screens, snacks getting smaller, too much ice in the drinks"

Cons: "Bag drop agent was not helpful."

Pros: "Nice on board crew."
Cons: "More arm & leg room in basic seating. Tray tables are flimsy and seem worn."

Pros: "The staff was very nice and helpful with prechecking my bag at the gate."

Pros: "Great crew, easy process overall"
Cons: "Make 1st class cheaper and give free wifi!"

Pros: "Seat comfort"
Cons: "Lot of turbulence. Provided videos/entertainment without providing headphones"

Pros: "Everything was good/adequate, nothing was exceptional."

Cons: "The in-flight entertainment in my seat did not work properly so I could not enjoy watching movies or shows. A minor but unfortunate inconvenience."

Pros: "Great crew, snacks, comfortable flight."

Cons: "Can't tell how the flight was because missed connecting flight from LAX to SJC because Westjet from YYZ to LAX had a mechanical issue. They end up replacing a tire which caused a 1.5 hr flight delay"

Cons: "Broken in-seat entertainment system for one of our seats, customs pre-clearance in Dublin took forever, but not the airline's fault."

Pros: "Service"
Cons: "Older aircraft"

Cons: "Not delay the flight for 3+ hours"

Pros: "The cabin crew was efficient and very cooperative. My seven hour flight in economy class could not have gone better. Kudos to Delta for a safe and comfortable ride."
Cons: "A few more audio selections would have been welcome."

Pros: "Very friendly cabin crew. Comfortable and food was good and drinks and water was plentiful. I would highly recommend Delta for transatlantic flights,compared to so called 4* airline Aer Lingus, then Delta are a 6* in comparison"

Pros: "Was gud"

Pros: "Good crew."
Cons: "Very tight spaces. No tv."

Pros: "Comfy seats, quick service."
Cons: "If you are in Zone 3 or 4 you pretty much have to check in your bag back there is no more room. Which I don’t understand and is highly incovienent."

Pros: "Service by the Delta team"
Cons: "Seats not roomy enough"

Cons: "Put me on an Aeromexico plane without a seat. When I went to get seat assignments she gave me very last seat with a “window” she said. There was no window. I was absolutely closterphobic"

Cons: "Not much food offered on a long flight."

Pros: "Seats were pretty comfortable, awesome flight, flight attendants were beyond excellent."
Cons: "Probably the time factor"

Pros: "Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations"
Cons: "The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes."

Pros: "I was traveling alone with my (cranky) infant son and the crew members were kind and accommodating. Though the flight was delayed by almost 2 hours, the crew worked quickly to ready the replacement plane and the pilot made up time and got us to San Jose as quickly and safely as possible."
Cons: "The original plane had mechanical issues, which caused an almost two hour delay while waiting for a replacement plane to arrive. Since I was traveling alone with my young son, after an already long previous flight, it made for a more difficult trip."

Cons: "Sat by the exit seat so the door was a bit more chilly. No food. Small entertainment screens with audio bleed through."

Cons: "It’s was the best flight in my life"

Cons: "Was in seat 16A and got bumped to 12E. If you know Delta aircraft, that's exit row window, for the EC (more legroom) but middle. The problem is that nothing can compete with the exit row for leg room and being crammed between two guys isn't an upgrade either. Plus, due to proximity, got sick. And the flight was delayed leaving - due to the late arrival from ATL (Delta HQ) which had a power outage. And no video entertainment. No meals."

Pros: "On time arrival"
Cons: "Small aircraft. Loud engine noise. Biased treatment for tickets booked on non Delta sites"

Pros: "No vegetarian options in first class.. and go go wouldn5 hook up. Flight was an hour late...but that was ok."

Cons: "Seat, did not get upgraded"

Pros: "Fast and comfortable"
Cons: "No tv but understanding"

Pros: "Crew was curious and quick to think of alternative solutions."
Cons: "The flight was way too hot. They didn't have enough A/C and we were all sweating up a storm on the flight. The flight was also scheduled to leave 15 min early, but we ended up leaving 15 minutes late, it was odd. One of the bathrooms was out of order too."

Cons: "There is just not enough leg room for a flight that long and the seats don't recline enough to be comfortable unless you upgrade and the tickets were already overpriced."

Cons: "Smooth"

Pros: "The flight was very on-time and it reached the destination even earlier than expected."

Pros: "I will know more on my flight back to my destination!"

Cons: "On this occasion I actually enjoyed it all"

Pros: "Flight was smooth and leg room great"

Cons: "No trash bag in my seat for puking or bubblegum"

Pros: "Comfortable plane"
Cons: "Travelled with some guys straight out of the Hangover movies. Going to Vegas for a Bachelor party and ogling and making comments on the flight attendant and other passengers! Nothing delta can do about that, It's part of life..."

Cons: "Seat pitch could've been more. At least let us know via Whatsapp that the plane is delayed, or at which belt the bags would come out. This basic info was lacking."

Cons: "They left my bag off the plane. Ridiculous."

Cons: "Service was poor, seat did not recline, and the food was terrible."

Cons: "I have ordered Wheelchair for my parents which one of my parent didn't get it on Mumbai Airport. When they arrived on Amsterdam Netherlands Airport they were dropped to the gate assigned first and once the gate changed on the fly no body came to help them moving to the new gate assigned which was far away to walk. Nobody even came to tell them that the gate has been changed. It was because of my father's alertness they didn't miss the connecting flight and when my father asked help to members on airport none of them helped my parents and other 4 co passengers which also were on wheel chairs. It was so scary experience for them that they asked me not to book any more flights with Jet Airways. I won't recommend Jet Airways to any of my friends for their parents to travel to USA. I strongly recommend you guys to take a strict action against this. This is so unacceptable."

Pros: "Landing"
Cons: "I’ve traveled a lot internationally and this was the WORST flight I’ve ever had to endure. I felt like I was being tortured and didn’t sleep at all and so slept when getting into Amsterdam rather than being able to explore the city. I was out $200 for the Airbnb (could’ve stayed in the airport cheaper) and $200 for a dinner cruise I slept through. NEVER AGAIN"

Pros: "The staff tried to help me when it was evident we would not arrive on time"
Cons: "The connecting flight is too short of a time. We were late out of LAX and I missed my connection and had to sit in airport for 5 hours. Missed my grandson’s third birthday party. Just made me sad as Travelled from far to try to make it."

Pros: "punctuality of boarding and flight time"
Cons: "attitude of crew in business class: no sense of true hospitality"

Cons: "Approx. 1 hour delay, which was not the airline's fault (construction on runways)"

Cons: "Bit cramped for space"

Pros: "Good flights. Good prices."

Cons: "They stole my money"

Pros: "787 is a great airplane. The 3-3-3 seat configuration leaves enough seat width to be just comfortable in coach."

Pros: "The supplied pack of toothpaste/toothbrush"

Cons: "The Guy who had an accident when boarding causing a delay. Also I didn’t like the wait fir checking as passengers with children went before business class and should be after."

Cons: "Flight was delayed 8 hours. Arriving at Incheon, discovered ground crew were unaware of our arrival to take this connecting flight. However, we were put up overnight in a hotel, which was nice."

Cons: "OLD plane without comfort or entertainment"

Pros: "Arriving more or less on time"

Pros: "Catering is ok"
Cons: "Seats comfort really old school"

Pros: "They were awesome."

Cons: "Food wasn't good, no entertainment or accessory plug ins, and seats were worn out! Not comfortable at all. Great leg room though."

Cons: "Flight delayed, had to take two more flights and was a four hour trip turned into a 12 hour, 4 countries trip"

Cons: "Luggage (being handled by Air France in Basel) was first marked as delayed... nothing of the flight was in the end put on the belt and instead dropped off at Lost and Found. Ridiculous service since this was in no way announced to the people waiting for their suitcase."

Pros: "Overall very nice flight, even comes with free drink and snack"

Cons: "Very slow service. I wanted to by several goods from duty free. But crew served only first 20 rows of aircraft."

Pros: "Good food, good entertainment system, comfortable seating."
Cons: "Only one toilet working in business class. A crew member told me that it was a decision to fly with only one toilet to ensure no delay. There was a disgusting stench of sewerage for the complete flight from Amsterdam to Johannesburg. This was in all likelihood due to the broken toilet on the left side."

Pros: "Boarding was poor. Stood on bus for almost 30 minutes followed by long bus ride to plane. No apology. Crew service average at best."

Pros: "All Crew from check in to departing plane was wonderful! Best customer service of all the airlines I’ve flown with."
Cons: "The entertainment wasn’t working initially."

Cons: "This flight was cancelled"

Pros: "We finally got there."
Cons: "Make water available at Heathrow 5 (2drinking fountains for thousands) and no water or any drink on the plane."

Cons: "The flight was delayed by three hours; not sure how to fix that but it was annoying. For some reason the arm rests in the middle of the seats would not go fully back and I felt like the flight attendants were talking down to me. They also could have been having a bad day too with the flight. :/"

Pros: "Check-in staff was great at LHR - they were able to configure our seating so that the seat was empty between us."

Cons: "Group boarding was chaotic"

Pros: "Polite and helpful crew members."

Cons: "Despite the long layover, they managed to misplace one or bags at Heathrow."

Pros: "The crew on this flight were awesome!! They were friendly, warm, and very accommodating throughout the flight. Legroom was decent and overall flight was comfortable."
Cons: "There could have been more options with the food. Because we are vegetarians we were stuck with pasta and pizza-related food for the 11 hour flight. Quality of food was good however."

Pros: "I liked the crew."
Cons: "The food was terrible. Indian curry/ pasta and pizza. It was so cold in the plane that everybody had to wear something on their heads. The AC was blowing on my head for 11 hours. I have headaches, my sinuses heart and the food made me nauseous. It was impossible to sleep because of the low temperature."

Pros: "Crew did really well in their roles."
Cons: "BA are no different than all operators in the drive to put as many bums in as many seats as possible. News flash. Only so many sardines go in one tin. Make seats more comfortable and more leg room and we would pay the premium for that reputation as a caring, comfortable operator."

Pros: "The service was the best you could ask for"
Cons: "NO WIFI!!!"

Pros: "Good, thanks"
Cons: "not many options in food n juice, I asked for cookies ( basic thing ) , was not available even. No option for Bollywood movies in entertainment as lots of Indian fly in this Delhi - London - San Jose"

Pros: "Longer flights make for more friendly and relaxed crew members!"

Cons: "Boarding was a bit chaotic. It was business and the other high status groups, then everyone else. No boarding groups. For charging almost twice as much for a premium economy ticket, it would be great if we could board before economy at least."

Cons: "delay too long"

Pros: "The crew are always nice, trying to compensate for the lack of service provided by the company. sadly, its not enough anymore."
Cons: "Everything.. Check in was a nightmare, only one representative for over 50 people. and much more horrible behavior from once a great company, today nothing more than an over paid low cost one."

Cons: "No wireless. Seats could be wider."

Pros: "see above"
Cons: "see above"

Pros: "Friendly attendants."

Pros: "The flight crew including the flight attendants."
Cons: "Although the seats had some leg room more than many airlines, the leg room is tight for a ten hour flight. Again I paid money thinking I was purchasing more leg room. I’m not sure what the charge was for???"

Pros: "Everything. Professional staff."
Cons: "Nothing."

Pros: "NA"
Cons: "Lack of legroom"

Pros: "Crew were busy to make us more comfortable during the long trip, always smile. Food is better than I thought."
Cons: "Late departure."

Pros: "The staff were pleasant and did a great job serving passengers in a timely manner."
Cons: "- my headphone jack was broken so I had to ask to move 3 times, and then finally walked up to the back of the plane to ask to be seated somewhere else - This particular flight had an unusually high number of babies. I was seated next to a couple with twin babies and of course they cried every so often. Only a few rows away there were another two babies. - food selection was super heavy on sugar or carbs. Entre choices were pasta with tomato sauce or chicken with cheese ravioli. Almost no one chose the pasta. Please introduce healthier options with actual protein for meat eaters and vegetarians."

Pros: "Easy no hassle trip home"
Cons: "BA will receive a specific letter regarding our out bound experience from San Jose CA, and I would hope to get to speak to a BA representative about our experience as well."

Pros: "The empty seat next to us. Entertainment was good. The chocolate-orange pudding was terrific with coffee!"
Cons: "The uncontrolled screaming of a certain child on the flight. Unable to nap at all! Bad for an 11 hour flight."

Pros: "The food and the on screen entertainment was great"
Cons: "Leg room is an issue for me"

Cons: "Noarding was fast. Food same as a previous flight. Still stuck in the airplane 30 min afyer touch down with no air condition."

Pros: "Plane ldeparted and landed on time. Plane was nicer than expected but not the same quality as Airbus 320"
Cons: "Immigration was severely understaffed for number of people waiting Took an hour to process 50 people. Crew member unhappy by seat swap as had special meal request. Had moved only one seat to the left to help other passenger out."

Pros: "Entertainment System was pretty good. Food served was nice and overall I was pretty impressed with the crew.. Normally most of the European and American airlines crew has a lot of attitude and are not the friendliest of lot but this set of crew was pretty good. Seats were also not too cramped like AA or UA flights."

Pros: "Offfered to boarded early as I was traveling with my Son"

Pros: "The ease of San Jose airport. The nice, new, clean airplane."
Cons: "Food could be better. Also they ran out of most of the choices. We were in business class and for the price you should be able to get your choice. I do see British Airways does offer a pre-flight meal selection and I would use this next time."

Pros: "Efficient and polite crew and excellent entertainmemt!"
Cons: "Nothing!"

Pros: "Nice new airplane (787). On time. Good food. Plenty of fluids served."

Pros: "Routing"

Pros: "Great flight."

Pros: "Nothing"
Cons: "I was a sardine in a tiny tin for 10 hours."

Pros: "Fantastic service and easy process from start to finish."

Cons: "Missed flight due to connection delay"

Cons: "The diabetic meals lacked variety and there was no choice. I was given a chicken dish with potatoes and mushrooms for the first meal and then given another chicken dish with rice for the second . Unlike other passengers I was not offered a choice. Both meal had a high carbohydrate load as they came with a separate bread bun . The first meal had peaches for dessert but my second meal offering had no substitute for the cake given to other passengers. The snack box contained sweet and salty popcorn,salted crisps and malteasers which are to be avoided by diabetics . Overall my dietary needs were poorly serviced by BA on this flight."

Pros: "excellent we got upgraded to premium economy so all was good"

Pros: "I had no trouble keeping myself entertained on the 10-hour flight from London to California. There were tons of movies to choose from, and that's not even counting all the television shows that were available. It's good that there are so many options b/c there is no wifi available for purchase."
Cons: "Not really related to the flight itself, but this was my first time flying British Airways, and they have a policy where you can't pick your seat until 24-hour in advance unless you pay an extra fee to choose early. I thought this was similar to Southwest's early bird check-in where no one really opts to pay for such a feature, but apparently with British Airways, everyone pays to pick a seat early. I checked in to my flight literally one minute after the site opened up and there were only middle seats left. So, if you've never flown BA before and you have a long flight, you might want to pay the extra fee to choose your seat early."

Cons: "I HAVE FLOWN OFTEN ON OTHER AIRLINES & IT WAS THE FIRST TIME TO FIND OUT THAT BRITISH AIRWAYS ONLY ALLOWED ONE FREE CHECKED BAG AND I HAD TO PAY $200 WHEN I ARRIVED AT THE AIRPORT, $100 FOR THE 2ND BAG & $100 BECAUSE IT EXCEEDED 51 LBS"

Pros: "Flight left and arrived ontime and early both departure and arrival."
Cons: "Seats are a bit uncomfortable in economy,"

Cons: "The TV interface was not great and a little slow"

Pros: "My 2-year-old son accidentally pressed the flight attendant button twice in his seat and once in the bathroom, but I didn't get yelled at by the flight attendants. I really appreciated that."
Cons: "One of my pieces of luggage was lost, but it arrived about 4 days later. It came back in perfect condition, which is great."

Cons: "Ramps up to the plane are a challenge for someone with movement problems. They had a mechanical issue that delayed departure for almost an hour for lack of a single screw."

Pros: "Got me to my destination"
Cons: "Attendants were less than welcoming with NO sense of humor. I found an empty whiskey container in the area under the seat in front of me. When I jokingly said that I found it empty and could she refill it for me, the attendant went off on me, telling me that she was too busy and couldn’t take it"

Pros: "The tv and drinks"
Cons: "Being told why we’re delayed and then not being kept on board for so long once we arrived late"

Cons: "In a period of 20 minutes in the hour before boarding there were three gate changes. The last one was a change of terminal and gate. You have been doing this for years and you should know how to do this already."

Cons: "Constant delays, wrongful promises of when/how long delays would take"

Cons: "Delayed"

Pros: "The Seats have a nice width and a nice forward-to-back pitch. They're also brand-new upholstery. Very nice"

Cons: "Nothing"

Pros: "Crew very friendly couldn't be more helpful. Food snacks and drinks good. Very efficient boarding system the best I've encountered."

Pros: "Fast and early"
Cons: "Tv screens kept freezing"

Cons: "At least one of the entertainment systems wasn't working right. Otherwise everything was okay."

Pros: "People actually boarded by group number"
Cons: "Sitting in premium economy still doesn't giive enough room to spread out papers and get work done. Out of four segments I only got upgraded once despite having 16 upgrades in my account."

Pros: "Nothing"
Cons: "Miserable food. Just horrible quality. Truly - and I'm not picky."

Cons: ""Parked" on tarmac for 25 minutes waiting to leave LAX. Arrived half an hour late"

Cons: "The staff, specifically Stephen, need to focus when serving who he served and where he left off! 5 passengers were not served at all until they came around for trash which we did not have! Then were told there were not any full meals left! If you booked that many tickets the amount of meals should match!"

Pros: "Everything! Leg room"
Cons: "The touch screen for entertainment was maddening!"

Cons: "We did not get the seats we purchased but we did get a refund"

Cons: "Planes too old"

Pros: "Staff was kind."

Pros: "Everything went smooth. Staff were professional and friendly"
Cons: "Nothing."

Cons: "Lousy food. Cramped seats, try to make you pay extra for seats to sit together,"

Pros: "I like that it's open seating."

Pros: "On time"
Cons: "No gluten free food available"

Pros: "I had lots of space to my self"

Pros: "Individual screens worked well, food was good."

Cons: "No entertainment systems Chairs were old and uncomfortable"

Pros: "The woman at the counter was helpful and cheerful."
Cons: "The experience was poor due to a flight delay that would have resulted in a missed connection. This resulted in a very negative effect because I won't be able to make an important business meeting."

Cons: "Slight delays in taking off but I understand this was not the airline’s fault."

Cons: "I am claustrophobic and the only opportunity I had to select a seat was when I checked in 24 hrs before the flight. The only aisle seat left was in the back row of the plane. Between the person in front of me fully reclining their seat and my inability to fully recline my own seat (airplane design) and with pepole standing in the aisles waiting for the toilets - I was very uncomfortable for most of the flight. United also had problems with their entertainment system so for an 8 hour long flight, there was much room for improvement."

Pros: "Flight delayed overnight, no compensation from United as no crew available after weather delay"
Cons: "United would not give any compensation for overnight delays as a disabled person very uncomfortable trip"

Pros: "The entertainment can stream a large library of movies to your device"

Cons: "The sit was so croweded"

Pros: "You cannot watch shows or.movis on demand. You can only watch TV movies, commercials and all"
Cons: "We weren't allowed in the Premier Lounge even though we had first class tickets. They said only international passengers."

Pros: "The flight was on time and I had plenty of leg room in Economy Plus."
Cons: "Too many crying babies and children. (Flights need a section for young children and infants.) I can handle a 2 hour flight, but not 7+ hours of constant noise) The chicken curry rice was not cooked all the way and the food was lukewarm."

Pros: "I was impressed by the food. Tasty and plenty of tea and coffee."
Cons: "They made a big deal at the gate about downloading the United App to be able to watch free movies. The WiFi didn’t work at all for me and others near me. I did see a couple of people watching movies, so it’s possible some folks were able to get a good connection. Good thing I had my kindle! Also, my bag and the bags of a few other people didn’t come through after UA22. There was a woman working at the computer at baggage claim #5 (I didn’t get her name) who called and radioed people regarding our missing luggage. It eventually showed up, but we were all getting very nervous because of the long delay. Thanks to that woman, it all turned out fine."

Pros: "Not a lot of positive to say"
Cons: "Ignorant, rude air hostess, two male hostess, double act the pair of them, if they had of been recorded they would be first today. As I said in my headline, if you hate your job that much find one that makes you happy, United need to do secret shopper experiences on their planes, to quality check their hostess, this cowboys are representing your company and its not good."

Pros: "Great selection of movies; on time departure and arrival much appreciated."
Cons: "Food was poor"

Cons: "VeRy long flight that didn’t need to be as long. Small plane. Hard landing and very quick stop where where everyone screamed."

Pros: "On time"
Cons: "Tight seats, boarding process"

Cons: "power plug didn't work"

Pros: "Free World Series viewing"
Cons: "No power outlets at seat"

Cons: "I couldn’t pick my seats online. Having to take that extra step at the airport was a hassle. Also we that way I wasn’t guaranteed to be sitting with my husband."

Pros: "They staff was friendly and they boarded efficiently."
Cons: "The worst part of the flight was the fact that they have redesigned their planes. They have put the seats even closer together and their new seats are horribly uncomfortable. The seats are made out of a hard molded plastic. There is no give and they don’t form to you back at all. Their comfort level I would rank at a zero! I had thought they may not be bad for a domestic flight as mine was international, however, I also had them for a domestic and they were equally uncomfortable. I will be checking off of United on my next flight as I can not sit in a seat this uncomfortable ever again! Try again United!!! #UnitedSeatsUncomfortable, #HorridSeats,"

Cons: "I would like to have a response from United Airline , my email address is pamm. strickland @ gmail.com"

Pros: "Same as above."
Cons: "Same as above."

Pros: "Cheapest flight I could find"
Cons: "No in flight entertainment. My Screen was broken and flight attendants did not fix it so I spent the entire flight in silence"

Pros: "The flight was almost empty so I had 3 seats to myself"

Pros: "Nothing"
Cons: "After the gates closed, an exit light broke and the staff took over an hour to fix it. Flight delayed."

Pros: "The movies were good - glad it was free and nice selection"
Cons: "US Pre-clearance in Dublin was ridiculous. I don't know what else to say about it. They were even holding us going down the escalator to the actual screening part. It was just one crazy queue to another. Will definitely make me think about ever going through Dublin again."

Pros: "Delayed outbound so I got to CA much later than I needed to be."

Pros: "quick boarding"
Cons: "no outlets!"

Cons: "."

Pros: "I thought the in flight entertainment was great, the food was decent, and the seats were comfortable."
Cons: "The whole cabin was way too cold from the beginning and never got warmer. The landing also left a bit to be desired, there was no apparent reason for the rocky landing, and I was left feeling nauseous for over an hour after."

Pros: "Departure on time, arrival early! No problems at all."

Pros: "Boarding was great and the in flight food and beverages were great. The choice of entertainment was awesome."
Cons: "Nothing"

Pros: "Male flight attendant was so genuinely kind to an elderly couple next to me. Female was nice as well. Seat more comfortable than last flight. Flight on time."
Cons: "Cannot connect to wifi. No entertainment. Need stronger signal. No charging spot for electronic device in my seat."

Pros: "Left on time"
Cons: "Crammed unconfortable"

Pros: "Staff was wecoming and friendly"
Cons: "Couldn't even access united's flight map without paying for movies. Seats are very small, large neighbor next to me used my armrest the whole flight and generally spilled into my seat."

Pros: "The crew were nice"
Cons: "Your entertainment sucks everything cost so much. There is NO leg room. Your planes I think are old needs to be updated."

Cons: "The flight was delayed over an hour. Caused me to miss my connection in Newark and delayed getting to Charlotte."

Pros: "Ok"
Cons: "None"

Pros: "Everything was great but my tv monitor was broken"

Pros: "wasn't lufthansa, I purchased a Lufthansa ticket but was really a United flight. very cramped seats. bad food, and service. the person next to me fell asleep and when he woke they had taken the food off his tray table, he then went back to ask for food and they rudely said no. there were tv's so that is a plus. will be more careful booking next time"

Pros: "Flight attendants were very nice. I enjoyed the movies"
Cons: "I could not choose my seat and ended up in a middle seat. Not my preference! The sandwich was on a stale roll with almost no turkey or cheese in it."

Cons: "The only negative was that after waiting to taxi (for almost 10 minutes), we received an announcement that it would be a little longer because they realized that the had yet to re-fuel the plane. That was somewhat alarming."

Cons: "Connecting flight Delayed 8hrs. Missed flight"

Pros: "On time; very attentive flight crew"

Pros: "Online confirmation"
Cons: "My seat assignments were changed and we were at the end of the plane next to the bathroom. I know I didn't put those. I don't like the fact that you have to pay for baggage and there is no food provided other than a drink and some really poor substitute even for peanuts. Southwest at least allows you to have a free baggage. It's not the fault of the pilot but it also is very bumpy. The flight crew was fine and it's just the uncomfortable aspects of having my seat assignment changed and the extra charges for anything that makes it comfortable."

Pros: "the boarding was easy, the crew was nice and attentive and brought plenty of water. WiFi worked much better than other flights."
Cons: "the food was not very good and the seats were not very comfortable"

Pros: "Average experience. Mostly pleasant enough."
Cons: "United changed our flight with No chance to object. Then reassigned us to separate seats. We asked to be moved next to each other. We were repeatedly and rudely dismissed 3 times, at 3 different levels, as if we were in the wrong to ask. If not for the kindness of a fellow passenger we would not have flown together. Very poor hospitality training."

Cons: "Terminals were a bit far a part"

Pros: "Nothing, worst flight I've ever had."
Cons: "Dried throw up on the floor in front of my seat.disgusting. SO MANY FLIES IN THE CABIN!!! Crew seemed like they hated their jobs, were NOT attentive. wasn't cleaned at all. Plane smelled. Charge port didn't work. Tray was extremely dirty. It was the worst flight I have ever had and is making me dread flying United back home."
